Preguntas frecuentes sobre las 6 bandejas para huevos

  • How far in advance should I order for a seasonal deadline?

    Más de lo que la mayoría de los compradores esperan, y el motivo radica en el proceso de aprobación, más que en la producción. La aprobación del tono de un color personalizado, la revisión de las pruebas de impresión de una tirada y el transporte marítimo son pasos que tienen lugar antes de la fecha en la que necesitas tener las cajas en tus manos. Los pedidos de temporada que fracasan lo hacen casi siempre debido al ciclo de aprobación, más que a la fabricación.

  • Do these cartons meet food contact requirements?

    Los huevos se encuentran dentro de su propia cáscara, por lo que, en la mayoría de las jurisdicciones, los cartones de huevos se consideran envases de contacto secundario con los alimentos, y no de contacto directo. Los requisitos siguen variando según el mercado, especialmente en la UE, por lo que los compradores deben confirmar cuáles son las normas aplicables en el lugar donde venden. Facilitamos declaraciones de materiales previa solicitud para que su equipo de cumplimiento normativo pueda evaluarlas en función de la normativa local.

  • Can I order more than one cell count in a single shipment?

    Sí, y la mayoría de los compradores lo hacen. Los pedidos mixtos se presupuestan por línea y se agrupan en un único contenedor, lo que suele resultar más económico que los envíos por separado. Lo que cambia es la planificación de la producción, ya que cada molde se procesa por separado, por lo que un pedido mixto puede tener un plazo de entrega ligeramente más largo que uno de un solo formato con el mismo volumen total.

  • What is the difference between a molded pulp egg carton and a molded fiber one?

    Nada relevante. Ambos términos describen el mismo proceso y el mismo material, y los compradores los utilizan indistintamente según la región y el sector. La fibra moldeada es más habitual en el sector electrónico y en los embalajes industriales, mientras que la pulpa moldeada se utiliza más en los sectores alimentario y agrícola. Ambos términos se refieren a la fibra que se extrae sobre un molde al vacío y se prensa para darle forma.

  • What happens if a carton specification does not work once we test it?

     Tell us what failed and how. Most fit problems trace to cell depth against an egg size we were not told about, and that is correctable. We would rather sample, have you test with your actual eggs and your actual handling, and adjust before a production run than ship a container of cartons that do not fit.

Caja de cartón moldeado para una docena de huevos

  • Can one mold cover both brown and white eggs?

    Sí. El color de la cáscara no influye en el ajuste del huevo en la caja. Lo que sí influye es la clase de tamaño del huevo. Una caja diseñada para huevos grandes admite tanto huevos grandes de cáscara marrón como de cáscara blanca de la misma forma, ya que la norma de clasificación se basa en el peso y no en el color de la cáscara.

  • Do you supply cartons pre-labeled with grade shields?

    Imprimimos el material gráfico que nos facilites, incluidos los distintivos de calidad y los códigos de planta. No generamos ni verificamos el contenido normativo, ya que la asignación de calidades y los códigos de planta te los facilitan a ti y varían según la jurisdicción. Facilítanos archivos listos para imprimir y los reproduciremos exactamente tal y como están.

  • What causes the hinge to crack on a pulp carton?

    Casi siempre se aplica una presión insuficiente en la línea de bisagra, donde la fibra es más fina por diseño. Un conformado correcto deja suficiente densidad de fibra para permitir aperturas repetidas. Si las cajas se agrietan al abrirlas por primera vez, es que la presión del molde o la consistencia de la pasta de papel no eran las adecuadas. Se trata de un problema de control de la producción, más que de una limitación del material.

  • How much does the printed version cost above blank?

    La impresión flexográfica conlleva un coste de plancha por color, además de un pequeño coste unitario que se reduce a medida que aumenta el volumen de tirada. Por debajo de un determinado volumen, el relieve resulta más económico, ya que el coste está incluido en el molde y no se repite. El punto de equilibrio depende del número de colores que se necesiten. Te ofrecemos presupuestos para ambas opciones, para que puedas ver el umbral de rentabilidad en función de tu volumen anual.

  • Can a dozen egg carton run on an automatic packing line?

    El formato 2×6 suele ser compatible, ya que la mayoría de las líneas se han diseñado en función de él. Lo que importa es la tolerancia en el ancho de entrada y la rigidez de la bisagra de la tapa, ya que las cerradoras automáticas aplican fuerza en un punto fijo. Envíanos la marca y el modelo de tu línea y te confirmaremos la compatibilidad antes de que te comprometas con el utillaje, o te proporcionaremos cajas de muestra para que realices una prueba.

Caja de 18 huevos de pulpa moldeada

  • Is this carton accepted in curbside recycling?

    It depends on the municipality rather than the product. Molded pulp egg cartons are made from short recycled fibers that have already been through several cycles, so some paper streams accept them and others direct them to compost. The carton composts in a home pile regardless. We advise printing a disposal instruction that matches your primary market.

  • How do you test top load strength?

    Compression testing on a filled carton under progressive load until deformation, reported as the load at first structural failure. The figure only means something alongside the test method, the conditioning humidity, and whether the carton was tested filled or empty. We report all four, and we recommend asking any supplier for the same.

  • Can you produce this format with a flat top instead of a domed lid?

     A flat top gives a better print surface and stacks marginally tighter, but it needs the reinforcing rib to be deeper to compensate for the lost arch strength. We tool flat top eighteen counts as a custom mold rather than stock, so allow additional lead time.

  • Why does the eighteen count cost more per egg to package than a dozen?

    It uses more material per egg than you might expect, because the reinforcing structure adds fiber that a twelve count does not need. It also prints at a higher cost per unit and nests slightly less efficiently. The packaging cost per egg is usually modest but it is not lower than a dozen, which surprises buyers who assume bulk always wins.

  • Will an 18 egg carton fit a standard refrigerator door shelf?

    In most US refrigerators, yes, which is a large part of why the format sells. The carton runs about 305 mm long and 155 mm wide, which clears typical door bin dimensions. Compact and apartment sized refrigerators are the exception, and buyers targeting urban markets sometimes prefer two dozens for that reason.

Caja de 4 huevos de pulpa moldeada

  • Are these suitable for shipping fertile hatching eggs?

    Many breeders use them for exactly that, inside an outer box. The deep cell immobilizes the egg, which matters more for hatch rate than cushioning does, since it is movement and rotation that damages the air cell. We do not make hatch rate claims, since outcomes depend on handling and transit time well beyond the packaging.

  • Do four counts nest as tightly as larger cartons?

    Tighter, proportionally. The compact footprint and simple 2×2 geometry give a very clean nesting profile with no interrupting features. On a per egg basis, four counts occupy more container volume than a dozen because you ship three times as many cartons for the same eggs, so the freight advantage runs the other way.

  • Can I order four counts in a color that is not one of your six stock shades?

    Yes. Custom pigment matching runs at a higher minimum than stock colors because the pulp slurry has to be batched specifically. Send a Pantone reference or a physical sample and we will produce a match sample before the full run. Expect a slight variation between pulp and a printed reference, since pigment behaves differently in fiber than in ink.

  • Why is the cell deeper than on your dozen carton?

    Because four count buyers are usually packing larger eggs. Duck, jumbo, and heritage breed eggs all need more depth than a commercial large chicken egg. We cut the four count to the larger specification so it fits the products that actually ship in fours, rather than optimizing it for an egg size that rarely uses this format.

  • Is a 4 egg carton strong enough to ship on its own?

    Not as a standalone parcel. It handles compression well but it has no drop protection at the corners, and parcel networks drop packages routinely. Use it as the inner carrier inside a rigid outer box with void fill. In that configuration it performs better than foam inserts and costs less.

  • What is the shelf life of a quail egg, and does the carton affect it?

    Unwashed quail eggs stored cool typically hold quality longer than chicken eggs relative to their size, because the shell membrane is dense. The carton does not extend or shorten that. What pulp does contribute is moisture regulation, since fiber neither traps condensation against the shell nor dries it out the way a sealed plastic pack can.

  • Do you supply quail cartons with a clear window?

    Windowed cartons require a plastic film insert, which breaks the single material construction and prevents the carton from composting as one unit. Buyers who want the eggs visible usually specify an open top tray inside a printed sleeve instead, which keeps everything fiber based.

  • Can quail cartons be printed, given how small the panel is?

    Yes, but keep it to one element. A twelve cell quail lid gives around 90 square centimeters, enough for a brand mark and a short line of text. Embossing tends to work better than print at this scale because it does not need registration accuracy on a small curved panel.

  • How many quail eggs equal a chicken egg for recipe purposes?

    Roughly four to five quail eggs match one large chicken egg by volume, since a quail egg runs 10 to 14 grams against about 57 grams. This is why twelve and twenty-four are common retail counts rather than six. It is worth stating on the pack, because shoppers new to quail eggs consistently ask.

  • Will these cartons fit Bobwhite and Button quail eggs as well as Coturnix?

    Coturnix and Bobwhite both sit correctly, since their eggs fall within a similar size band. Button quail eggs are noticeably smaller at around 20 mm and sit loose in a standard quail cell. If you run Button quail exclusively, we recommend custom tooling rather than accepting a loose fit.

Chicken Egg Carton

  • Do you supply cartons that work on Moba or Diamond grading equipment?

    We supply to dimensional specification, and buyers running Moba, Diamond, or Sanovo equipment provide us the required carton tolerances from their machine documentation. We then produce and sample against those figures. We do not certify against specific equipment brands, since certification sits with the machine operator’s own trial.

  • How does molded pulp compare to foam on egg breakage rates?

    Both perform well in transit, and neither has a decisive edge on breakage when correctly specified. The differences that matter commercially are elsewhere: pulp composts and foam does not, pulp nests for lower inbound freight, and an increasing number of retailers and jurisdictions restrict foam. We do not produce foam, so we would rather state that plainly than argue a performance gap that the data does not support.

  • Can I use the same carton for washed and unwashed eggs?

    The carton does not differ. What differs is handling and storage, since washed eggs have lost the natural cuticle and need refrigeration, while unwashed eggs can be held at room temperature in many jurisdictions. Pulp handles both because it regulates moisture rather than sealing it in.

  • Does a pullet egg need a different carton?

    Pullet eggs from young hens fall into the peewee and small grades, roughly 35 to 43 grams, and they sit low in a standard bed. They are safe there, but they look sparse in the carton, which matters for retail presentation. Producers selling pullet eggs as a distinct product often use a shallower dedicated mold so the pack looks full.

  • What egg grade should I specify if my flock lays inconsistently?

    Specify to your largest regular egg, not your average. A smaller egg in a deeper cell is protected. A larger egg in a shallow cell takes lid pressure and cracks. Most mixed flocks are best served by the deep bed, which covers extra large and jumbo while still holding large eggs securely enough for transport.

Cajas de huevos de pulpa moldeada de colores

  • ¿Puedo recibir una carta de colores antes de hacer el pedido?

    Sí, y lo recomendamos. Las representaciones en pantalla del color del papel de pulpa no son fiables, ya que la textura de la fibra influye en el tono que se percibe. Enviamos muestras físicas de color de los seis tonos disponibles y, para los trabajos a medida, elaboramos una muestra moldeada con la geometría real del cartón, ya que una muestra plana y una superficie moldeada se perciben de forma diferente.

  • ¿Se transfiere el pigmento a las cáscaras de los huevos?

    No. El pigmento está integrado en la estructura de la fibra, no se encuentra suelto en la superficie, y la pulpa seca no transfiere el color en condiciones normales de manipulación. Una caja que manche los huevos indicaría que se trata de un producto con un recubrimiento superficial de escasa adherencia, lo cual constituye uno de los argumentos prácticos a favor de la coloración en fase húmeda.

  • ¿Por qué los cartones de colores son más caros que los naturales?

    Tres razones. El propio pigmento supone un coste adicional de material. Los cambios de color en la sección húmeda obligan a purgar el sistema entre un tono y otro, lo que supone tiempo de inactividad. Además, las tiradas de color no pueden adaptarse a las variaciones en la fibra entrante como lo hace la producción de hilo natural, por lo que se rechazan más lotes por diferencias de tono. Los colores en stock son más baratos que los personalizados porque los producimos de forma continua y evitamos la mayor parte de los cambios de configuración.

  • ¿Podéis igualar exactamente el color de mi marca?

    Podemos acercarnos bastante y elaboramos una muestra física antes de iniciar la tirada completa para que puedas aprobarla o realizar ajustes. No es posible lograr una coincidencia exacta con una referencia Pantone impresa en fibra pigmentada, ya que la pulpa dispersa la luz de forma diferente a como lo hace el papel estucado. Las marcas con un estándar de color estricto suelen aprobar un equivalente de pulpa designado en lugar de insistir en la referencia de tinta.

  • ¿Se decoloran las cajas de cartón de colores con la luz del sol?

    Poco a poco, y sobre todo en un puesto de productos agrícolas más que en una vitrina refrigerada. Los pigmentos de la pulpa son menos resistentes a la luz que las tintas de impresión, ya que la paleta de colores se limita a compuestos biodegradables. Las cajas de cartón expuestas a la luz solar directa durante semanas se aclararán, sobre todo en la gama de los azules y morados. Las vitrinas refrigeradas de las tiendas y los puestos cubiertos de los mercados no suponen ningún problema.

Cajas de huevos de pulpa moldeada de color rosa

  • How long does a custom pink shade take to approve?

    Sample production runs to a physical formed sample, which is what you should approve rather than a flat chip. Building the shade, forming samples, and shipping them for approval takes time before production can begin. We recommend starting the approval cycle well ahead of a seasonal deadline, since October and Easter campaigns fail on timing far more often than on color.

  • What egg shell color looks best in a pink carton?

    Brown and blue-green shells give the strongest result, since both contrast against pink. White eggs in a blush carton can look washed out because the tonal values sit close together. Producers running white eggs usually specify mid pink or deeper for that reason.

  • Can pink cartons be used for a compostable claim?

    Yes, on the same basis as our natural cartons. The pigment is selected for compostable packaging use and is present in very small quantity by mass, with no coating or film involved. As with any compostability claim, the wording should match the certification actually held and the disposal infrastructure in your market.

  • Does pink cost more than your other stock colors?

    Slightly, and the reason is rejection rate rather than pigment cost. Because pink is a light tint over a variable gray base, more batches fall outside the shade tolerance and get diverted. Darker colors absorb base variation and run cleaner. The difference is modest but it is real, and any supplier quoting all colors identically is probably not shade checking.

  • How much shade variation should I expect between orders?

    With a retained physical standard on file, variation is small enough that cartons from different runs look the same on a shelf side by side. Without one, expect noticeable drift, since incoming recycled fiber varies seasonally and pink shows that variation more than any other shade. Approving and retaining a standard at first production is the single most useful thing a pink buyer can do.

Cajas octogonales para huevos de pulpa moldeada

  • Can you produce shapes other than eight sided?

    Hexagonal and square footprints are both producible, and we have tooled round formats for specific gift applications. Facet count changes the internal cell layout, so each shape needs its own cell arrangement worked out at design stage rather than being a variation on the octagon mold.

  • Does the octagonal shape protect eggs better than a rectangle?

    On corner impacts, modestly, because eight corners share load that four would concentrate. On compression and stacking, the two are comparable, since load path in both cases runs through the internal cone structure rather than the outer wall. The shape is chosen for presentation, and the impact benefit is a secondary advantage rather than the reason to specify it.

  • What is the practical minimum order for a custom octagon shape?

     Higher than for a rectangular carton, because the tooling is more complex and the mold cost has to be recovered. Buyers testing the format should start on one of our existing octagon molds, which carries no tooling charge, and move to a bespoke facet count or dimension once the line is proven.

  • Can an octagon carton run through automatic packing equipment?

    Generally not. Automatic lines are built around rectangular infeed geometry and expect a consistent leading edge. Octagon cartons are hand packed in almost every operation we supply. That fits their use case, since premium and gift volumes are usually low enough that hand packing is not a constraint.

  • Do octagon cartons stack on a pallet as securely as rectangular ones?

    They stack, but the pallet pattern is less efficient because octagons leave void space between units. The stack itself is stable, since each carton sits flat on the one below and the eight corners spread the load. What you lose is cube utilization, so allow for fewer units per pallet than a rectangular equivalent of the same cell count.

Cajas de huevos vintage de pulpa moldeada

  • ¿Se romperá la bisagra profunda si los clientes reutilizan la caja de cartón?

    Si se abre repetidamente a lo largo de varias semanas, con el tiempo sí. El pliegue único y profundo concentra la flexión en una sola línea, lo cual es la contrapartida de que la tapa quede completamente plana. Las bisagras modernas con múltiples pliegues duran más a lo largo de los ciclos de reutilización. Si tus clientes devuelven habitualmente las cajas de cartón para rellenarlas, el perfil moderno es la opción más práctica.

  • ¿Caben las cajas antiguas en los estantes de las puertas de los frigoríficos modernos?

    El modelo de doce celdas tiene una altura ligeramente inferior a la de una caja de cartón abovedada moderna, con unos 68 mm frente a los 75 mm, por lo que encaja perfectamente en el mismo espacio que una moderna. La longitud es la misma. Los compradores que cambian de perfil no suelen tener que modificar nada en las fases posteriores del proceso.

  • ¿Puedo imprimir una ilustración a todo color en la tapa?

    Sí, y la razón es el panel plano. La impresión flexográfica multicolor mantiene el registro en una superficie plana de una forma que no es posible en una superficie abombada. Hay que tener en cuenta que la textura de la pasta de papel suaviza los detalles finos independientemente de la calidad de impresión, por lo que las ilustraciones con trazos marcados se reproducen mejor que las imágenes fotográficas.

  • ¿Se apila la tapa plana tan bien como una tapa abombada?

    De hecho, es incluso mejor. Una superficie plana se apoya directamente sobre la base de la caja de cartón situada encima, sin ningún contorno contra el que deslizarse, por lo que las pilas se mantienen rectas. Lo que pierde la parte superior plana es la resistencia al arqueamiento que proporciona una cúpula, lo cual compensamos con una estructura de nervaduras situada debajo del panel. El rendimiento neto frente a la carga superior es comparable.

  • ¿Las cajas vintage son realmente antiguas o son reproducciones?

    Se fabrican ex novo siguiendo un perfil histórico. Las cajas de cartón auténticamente antiguas no son aptas para el contacto con alimentos, ya que los envases de fibra absorben cualquier sustancia con la que se hayan almacenado y carecen de un historial de materiales trazable. Nuestras cajas de cartón vintage se fabrican a partir de la misma pulpa reciclada que el resto de la gama, utilizando moldes diseñados para reproducir la geometría de la parte superior plana.

  • Can I use duck cartons for chicken eggs to simplify my stock?

    You can, and the eggs will be safe, since a smaller egg in a deeper cell is protected rather than at risk. What you lose is presentation, because chicken eggs sit low and the carton reads as underfilled. Producers running both birds usually find the appearance penalty outweighs the simplicity of one SKU.

  • Do duck eggs need more ventilation than chicken eggs in packaging?

    No, and pulp handles both identically. Duck eggs have a slightly less porous shell than chicken, which is part of why they keep marginally longer unwashed. What matters is that the packaging neither traps condensation nor dries the shell, and fiber does neither because it regulates moisture rather than sealing it.

  • How do I know whether my Muscovy eggs will fit before ordering?

    Send us a few eggs, or send accurate measurements of your largest regular egg at both length and maximum girth. Length alone is not enough, since girth is what decides whether the egg seats or perches. We seat samples in a production carton and give you a direct answer rather than an estimate.

  • Are duck egg cartons more expensive than chicken?

    Per carton, yes, because deeper and wider cells use more fiber and the larger footprint nests slightly less efficiently per container. Per egg sold, the difference is small against duck egg pricing. Buyers comparing the two on carton cost alone are measuring against the wrong denominator.

  • Will a duck carton work for shipping hatching eggs?

     Inside an outer box with void fill, yes, and the deep cell is an advantage because it immobilizes the egg. Movement and rotation damage the air cell, which kills hatch rate well before the shell is at risk. We make no hatch rate claims, since outcomes depend on transit time and handling far beyond the packaging.

  • Can I get blank cartons with a flat top for easier labeling?

    Yes, and it is worth specifying if labeling is the plan. A flat top gives a genuinely flat label area rather than a slightly domed one, which improves both application accuracy and adhesion at the label edges. The flat top profile is covered on the cajas de huevos vintage de pulpa moldeada página.

  • Is a blank carton lower quality than a printed one?

    No. It comes off the same mold, at the same fiber density, with the same top load performance. The only difference is that no print pass was applied. Buyers sometimes assume blank means seconds or overruns, and that is a different product category entirely which we do not sell.

  • Can I order blank cartons in small quantities for a trial?

    Blank carries our lowest minimum because there is no tooling or plate cost to recover. It is the right product for a first order while you test a format. We would rather supply a small blank run and have you come back than push a printed minimum onto a buyer who is still deciding.

  • What label adhesive works best on molded pulp?

     General purpose permanent acrylic adhesives on uncoated paper face stock perform well. Avoid removable adhesives, which never develop sufficient bond on a porous surface, and avoid film face stocks, which lift at the edges. Your label supplier will know these as standard options; the substrate to specify is uncoated paper.

  • Will your company name appear anywhere on a blank carton?

     No. Blank means blank, including no supplier identification, no mold numbers visible on the outer faces, and nothing on the base. Distributors reselling under their own name need that to be absolute, and we treat it as such rather than leaving a small mark somewhere.

Cajas de huevos moradas

  • Is lavender a good choice for an Easter range?

    It is one of the standard four alongside pink, pale blue, and yellow, and buyers usually order the set together. Order them from one pigment campaign where volumes allow, so the four shades read as a coordinated family rather than as four separately matched colors.

  • Does purple cost more than your other stock colors?

    Slightly, for the same reason pink does. Two pigment components have to be balanced against a variable base, so more batches fall outside shade tolerance and get diverted. Stock purple costs less than a custom matched shade, since we run it continuously and avoid most of the changeover.

  • Can you produce a true violet rather than a blue-purple?

    We can move the balance toward the red end within the limits of compostable-rated pigments, and we send a formed sample so you can judge it physically. A highly saturated violet is outside what the available palette reaches, since the pigments that achieve it are not rated for compostable packaging. We will tell you plainly where a target shade sits outside our range.

  • How different will my reorder look from my first order?

    With a retained physical standard on file, close enough that cartons from different runs look the same side by side. Without one, purple drifts more visibly than most shades because the eye detects hue shifts sharply in this range. Approving and retaining a standard at first production is the single most useful step for a purple buyer.

  • Why is purple less common in egg packaging than other colors?

    Mostly inherited habit rather than any technical barrier. Egg packaging colors settled around natural, white, and green decades ago and the category has not moved much since. Purple is harder to hold consistently than mid-range shades, which discourages large converters running high volume, but for a specialty producer that difficulty is exactly what keeps the color uncontested.

Cajas de huevos ecológicas

  • ¿Está disponible el color verde en el perfil «flat top» vintage?

    Sí, y el color salvia, en concreto, es una de las combinaciones que utilizamos con más frecuencia. Este tono apagado se adapta mejor al estilo de la época que un verde brillante, ya que las cajas de mediados de siglo se fabricaban en tonos de fibras naturales, en lugar de en colores saturados.

  • ¿Podéis reproducir el tono de verde que utiliza una marca concreta?

    Ajustamos el color a una referencia Pantone o a una muestra física con la mayor precisión que permita la fibra pigmentada, y enviamos una muestra conformada para su aprobación antes de la producción. En la pulpa no es posible lograr una coincidencia exacta del color de la tinta. Si la referencia es una caja de cartón de la competencia en lugar de una muestra impresa estándar, envíanos la caja física y la igualaremos directamente con ella.

  • ¿Se desgastará el verde más rápido que otros tonos?

     Queda mejor que el azul y peor que el negro. Los pigmentos verdes homologados para su uso en productos compostables tienen una resistencia a la luz moderada, por lo que el tono «bosque» se mantiene bien y el tono «salvia» es el que se decolora antes cuando se expone de forma prolongada a la luz solar directa. En el sector minorista refrigerado, ninguno de los tonos de la gama se ve afectado.

  • ¿Qué variedad de verde eligen la mayoría de los productores ecológicos?

     Verde medio, porque es el tono que transmite con mayor claridad el mensaje de la categoría. Los productores que se posicionan por encima de la categoría en cuanto a calidad, más que en cuanto a método, suelen optar por el verde salvia o el verde bosque, que transmiten una imagen de gama alta más que de ecológico.

  • ¿Contribuye una caja de cartón verde a la certificación ecológica?

    No. La certificación se concede en función de las prácticas de producción y se somete a una auditoría independiente, por lo que el color del envase no influye en ella. Lo que hace el color verde es transmitir más rápidamente en el lineal una afirmación que ya posees. La marca de certificación en sí misma debe seguir figurando en el envase, de acuerdo con las normas de tu organismo certificador.

Cajas de huevos azules

  • Does blue cost more than natural pulp?

    Yes, as all pigmented shades do, and the difference comes from pigment cost plus the line flush required when changing color. Blue sits in the middle of our color range on price, above black on pigment cost per unit of coverage and below custom matched shades.

  • Is navy just black with less pigment?

    No, they use different pigment systems entirely. Navy reads as a dark blue under daylight and shows its blue cast clearly against a true black carton placed beside it. Buyers who want near-black performance with a hint of color choose navy deliberately rather than as a compromise.

  • Can you match a specific Pantone blue?

    We produce a close match and supply a formed physical sample for approval. Exact matching to a printed Pantone reference is not physically achievable in pigmented fiber, since pulp scatters light differently from coated paper. Brands with a strict standard approve a designated pulp equivalent rather than insisting on the ink reference.

  • How much fading should I expect at an outdoor market?

    Visible lightening after sustained direct sun across weeks, with pale sky showing it first and navy showing it last. Cartons used and sold within days never see enough exposure to matter. The problem is stock sitting in sun between market days, which is solved by covering the pile rather than by changing shade.

  • Which blue should I choose if my hens lay blue eggs?

    Pale sky, for a tonal match, or move away from blue entirely for contrast. Avoid mid blue and navy, which are strong enough to flatten a pale blue shell so the eggs stop registering as the distinctive thing they are. Order a sample and seat your actual eggs in it before committing.

Cajas de huevos negras

  • Will black pigment rub off onto eggshells?

    No. The pigment is bound within the fiber rather than applied to the surface, so there is nothing loose to transfer. Transfer onto eggs would indicate a surface coated carton with poor adhesion, which is one of the practical reasons we color at the wet end rather than coating afterward.

  • Does black cost more than your other stock colors?

    Slightly, because the pigment loading is higher by mass than for a light tint. That is partly offset by a lower rejection rate, since black does not fail shade checks the way pink and pastels do. Net difference against other stock colors is small.

  • Can you print a photograph in white on black?

    No, and not because of the color. Fiber texture breaks up continuous tone regardless of substrate, so photographic reproduction fails on pulp generally. A bold single color illustration in white on black reproduces well. A halftone image does not.

  • Will a black carton fade in sunlight?

    Less than any other shade we produce. Black pigment has more lightfastness headroom than light tints, because fading is a proportional loss and there is far more pigment present to lose. Cartons held in strong sun for months will dull toward charcoal, but the effect is slower and less visible than on pastels.

  • Does a black carton compost as readily as a natural one?

    Yes. The pigment is a very small fraction by mass and is selected for compostable packaging use, with no coating or film involved. Buyers sometimes assume heavy pigmentation means heavy additives, but the loading required to reach black in fiber is still minor against the mass of the fiber itself.

  • Do you make a combined carton for mixed specialty eggs?

    No, and we would advise against one. A carton with cells of several sizes wastes space on every cell that is not filled, and it only works if a producer reliably has one of each bird on hand at packing time, which almost nobody does. Separate cartons per bird is the practical answer.

  • Why do goose cartons cost more per egg than chicken cartons?

    Fiber quantity and freight. A goose cell uses several times the material of a chicken cell, and the larger footprint means far fewer cartons per container. Against goose egg pricing, which is substantially above chicken, the packaging cost per egg sold remains proportionate.

  • Are turkey eggs actually sold for eating?

    Rarely at commercial scale, and the economics explain why. A turkey hen lays far fewer eggs than a laying hen and the bird is worth more as meat, so the eggs are usually set for hatching rather than sold. Most of our turkey carton demand comes from breeders shipping fertile eggs.

  • How do I pack a flock that lays goose and chicken eggs together?

    Separately, and there is no way around it. The size gap is too large for any single mold to bridge without failing one bird or the other. Producers running both keep two carton lines, which is normal in mixed specialty operations and costs less than the breakage from compromising.

  • Can a bantam egg use a quail carton instead?

    No, and the mismatch runs the other way from what people expect. A bantam egg at 25 to 35 grams is two to three times the weight of a quail egg, so it will not seat in a quail cell at all. Bantam needs its own geometry, sitting between quail and standard chicken.
