A 12 egg carton holds one dozen eggs, and ours comes in two layouts. The long 2 x 6 format measures 300 x 105 x 75 mm (11.8 x 4.1 x 3.0 inches), and the compact 3 x 4 format measures 205 x 150 x 75 mm (8.1 x 5.9 x 3.0 inches). Both weigh 48 to 58 g, take standard to jumbo chicken eggs, and close with a locking front tab.<\/p>\n

The dozen is the standard retail pack, so small choices add up fast. A layout that does not fit your grading line costs hours. A lid that cannot hold your label text costs a reprint. This guide covers layout, size, egg fit, line compatibility, label rules, printing, color and testing, with real specs from the cartons we make in Dongguan, China.<\/p>\n

What Is a 12 Egg Carton and Which Layout Should You Choose?<\/h2>\n

A 12 egg carton is a molded pulp pack with twelve cells in one of two grids. Pick the 2 x 6 long format if you pack on a grading line, because most lines were built around it. Pick the 3 x 4 compact format if shelf depth is cheap and shelf width is tight. The table shows both.<\/p>\n\n\n\n\n\n\n\n\n\n\n

Both are formed from post-consumer recycled paper pulp by wet pressing, and both come in natural pulp, six stock colors or a custom match. The flat top style is also available in 12 cells. You can see the full spec on our 12 egg carton<\/a> page.<\/p>\n

The height is the same in both at 75 mm, so the choice comes down to footprint. The 3 x 4 is nearly square, which suits some display trays and gift boxes.<\/p>\n

How Big Is a 12 Egg Carton?<\/h2>\n

The long 2 x 6 carton is 300 mm by 105 mm by 75 mm, which is 11.8 by 4.1 by 3.0 inches. It is the same width and height as our half dozen, which is 175 x 105 x 75 mm, so a dozen is about 1.7 times the length of a half dozen. If you run both sizes, the matching width and height keep your cases and shelf bays easy to plan.<\/p>\n

Measure your own space before you order. The 3.0 inch height decides whether the carton closes in a tight refrigerator bay, and the length decides how many fit across a case. Our guide on egg carton sizes and counts<\/a> explains how a 4, 6, 12 and 18 compare.<\/p>\n

How Much Does a Filled Dozen Weigh?<\/h2>\n

A filled dozen of Large eggs holds at least 24 ounces of egg, which is 1.5 pounds, and the carton adds 48 to 58 g, about 2 ounces. Jumbo eggs bring the minimum to 30 ounces, or 1.9 pounds. These are USDA minimum net weights per dozen, so real eggs can weigh more.<\/p>\n

Twelve filled dozens in a box carry about 18 pounds of Large eggs, and the cartons at the bottom take that load. Our dozen uses a rib structure so the stacking load runs through the carton frame and not through the eggs. Check that on a sample by stacking filled cartons.<\/p>\n

Which Egg Sizes Fit a 12 Egg Carton?<\/h2>\n

Our 12 egg carton fits standard to jumbo chicken eggs. Fit depends on egg size class, not shell color. A carton molded for Large eggs holds brown and white Large eggs the same way, because the USDA grades eggs by weight and not by shell color.<\/p>\n

So you can use one mold across a mixed flock. What changes the fit is the spread of weights inside a size class. A flock sold as Large includes eggs from the 24 ounce per dozen floor up to just below the Extra Large floor. Test the heaviest and roundest eggs you pack, not only the average ones.<\/p>\n

Duck, goose and turkey eggs are bigger and shaped differently, so they need a test or a custom mold. Quail eggs need their own carton. We make a quail carton in 12, 18 and 24 cells.<\/p>\n

Will a 12 Egg Carton Run on a Grading Line?<\/h2>\n

The 2 x 6 format usually runs on an automatic or semi-automatic packing line, since most lines were built around it. What matters is the infeed width tolerance and the stiffness of the lid hinge, because machine closers apply force at a fixed point. We do not guess. Send us your line make and model and we will confirm compatibility before you commit to tooling, or we supply sample cartons for a trial run.<\/p>\n

Do the trial before the order, not after. A carton that closes by hand can still jam a machine closer, and a stopped line costs more than any saving on the carton. Run a few hundred samples at normal speed and watch for jams, crushed corners and lids that spring open.<\/p>\n

What Label Rules Apply to a 12 Egg Carton?<\/h2>\n

A dozen carton lid has to carry a lot of text, and some of it has a minimum type size. The USDA Agricultural Marketing Service lists the elements for USDA grademarked shell eggs<\/a>, including the grade shield, the egg size, the packer line, the safe handling box and the net content.<\/p>\n

From that guide, the egg size goes on the front panel in at least 1\/4 inch type, and the packer name and address in at least 1\/16 inch type. The safe handling instructions sit in a hairline box in at least 1\/16 inch type, and the word eggs must be bold and at least half the size of the largest print on the panel. Net content goes in the bottom 30 percent of the panel, in at least 3\/16 inch type for a 12 or 18 egg carton. Sellers who are not USDA grademarked follow state rules instead.<\/p>\n

States add more. Wisconsin, for one, asks for a date of pack, a sell by date no more than 30 days from pack and a use by date no more than 45 days from pack. It also says a reused carton must have every unrelated marking removed. Confirm yours with your state department of agriculture before you print. We print the artwork you give us, including grade shields and plant codes, but we do not create or check regulatory content, because those items are issued to you and differ by state. Our guide on egg carton labels and stamps<\/a> shows what most sellers print.<\/p>\n

How Do You Fit All That Text on the Lid?<\/h2>\n

Plan the required text first, then fit your brand around it. Our dozen has a full width lid panel that takes grade labels, nutrition text and brand marks without crowding. Keep the legal text in a fixed block that never moves between runs, and leave your brand to one mark and a short line. If the required text fills most of the panel, move extras to a sticker or choose the flat top style, which has a larger print surface. Lay a full size proof against a formed sample before you approve a run, because a flat proof and a pulp surface read differently.<\/p>\n

Should You Print the Carton or Use a Blank One?<\/h2>\n

Choose blank if your volume is low or your label changes often, and choose printed if your artwork is stable and your volume is steady. We supply both. Printing costs more up front but saves the labor of stamping or labeling every lid.<\/p>\n

Flexographic print adds a plate charge for each color, then a small cost per unit that falls as the run grows. Below a certain volume, embossing is cheaper, because the cost is built into the mold and does not repeat. The crossover depends on how many colors you need, so we quote both and you can compare them against your yearly volume. Debossing presses a mark into the lid and reads as quiet and premium. Pulp texture softens fine detail, so bold type and simple line art reproduce better than small text or photographs.<\/p>\n

Which Colors Come in a 12 Egg Carton?<\/h2>\n

A 12 egg carton comes in natural pulp, six stock colors and custom matched shades, with the pigment blended into the pulp so there is no surface coating. Pink, blue and green come in 12 cells, in pale, mid and deep shades. Color separates your lines on a shelf, and it helps staff tell a dozen from a half dozen or an 18 count in a mixed cooler.<\/p>\n

If you need a brand shade, we match to a Pantone reference or a physical sample as closely as pigmented fiber allows. An exact ink match is not possible in pulp. We send a formed sample for approval before production. You can compare the stock shades on our colored egg cartons<\/a> page.<\/p>\n

Standard Fold or Flat Top in 12 Cells?<\/h2>\n

Pick the standard top fold for a better hinge and a locking tab, and pick the flat top for a retro look and the largest print panel. The standard dozen is 300 x 105 x 75 mm. The flat top 12 cell is 300 x 108 x 68 mm, which is 7 mm shallower, so it stops at extra large eggs. The trade is hinge life, because a single deep fold cracks sooner than a multi crease hinge if customers reuse the carton. Our vintage egg cartons<\/a> page lists that spec.<\/p>\n

If you also sell a smaller pack, read how the 6 egg carton<\/a> compares, since the half dozen shares the same width and height.<\/p>\n

Why Do Hinges Crack on a Pulp Carton, and How Do You Check?<\/h2>\n

A cracked hinge is almost always a forming problem, not a limit of the material. The hinge line is where the fiber is thinnest by design, and under pressing leaves it too weak. If a carton cracks on the first open, the mold pressure or the pulp consistency was off. Test the hinge on every sample by opening and closing it a few dozen times, including once after the carton has been chilled, since your customers will do that.<\/p>\n

How Do You Test a 12 Egg Carton Before You Order?<\/h2>\n

Run a short test on a formed sample with your own eggs, in the conditions where you pack and sell. A carton passes when every egg sits on its cell floor and the lid closes with no pressure on a shell.<\/p>\n

    \n
  1. Seat your heaviest and roundest eggs and close the lid.<\/li>\n
  2. Check that the front tab locks with no force.<\/li>\n
  3. Stack three filled cartons and look for lid bulge.<\/li>\n
  4. Run a handful through your packing line, if you have one.<\/li>\n
  5. Open and close the hinge a few dozen times, including once after chilling.<\/li>\n
  6. Check that your required label text fits at the type sizes your rules ask for.<\/li>\n<\/ol>\n

    Keep the approved sample as your standard for reorders.<\/p>\n

    How Do You Order 12 Egg Cartons From BonitoPak?<\/h2>\n

    Send your layout, color and artwork idea to leo@bonitopak.com, and say whether you want a stock carton or a custom mold. Stock molds carry a lower minimum than custom tooling, and we confirm the exact minimum with each quote. You can order more than one cell count in one shipment. Mixed loads are quoted per line and shipped in one container, and each mold runs on its own, so a mixed order can take slightly longer.<\/p>\n

    Seasonal deadlines fail on approval time, not on manufacturing, so allow time for shade approval, artwork proofing and sea freight before you need cartons in hand. Egg cartons are generally treated as secondary rather than direct food contact packaging, but requirements vary by market, and we supply material declarations on request. Our product page describes the cartons as biodegradable and home compostable, so ask for the supporting documents before you print any such claim on your own pack. You can see the rest of the range on the BonitoPak homepage<\/a>.<\/p>\n

    Frequently Asked Questions<\/h2>\n

    Q: How many eggs does a 12 egg carton hold?<\/strong><\/p>\n

    A: Twelve eggs, which is one dozen. Ours comes as a 2 x 6 long format or a 3 x 4 compact format, and both fit standard to jumbo chicken eggs.<\/p>\n

    Q: What are the dimensions of a 12 egg carton?<\/strong><\/p>\n

    A: The 2 x 6 is 300 x 105 x 75 mm, or 11.8 x 4.1 x 3.0 inches. The 3 x 4 is 205 x 150 x 75 mm. Both weigh 48 to 58 g. Ask for a drawing before you plan case sizes.<\/p>\n

    Q: Can one carton mold hold brown and white eggs?<\/strong><\/p>\n

    A: Yes. Shell color does not change cell fit. Egg size class does, because eggs are graded by weight. A carton molded for Large eggs holds brown and white Large eggs the same way.<\/p>\n

    Q: Can a pulp 12 egg carton run on an automatic packing line?<\/strong><\/p>\n

    A: The 2 x 6 format usually can. Infeed width and hinge stiffness decide it. Send your line make and model, and we confirm compatibility or supply sample cartons for a trial run.<\/p>\n

    Q: Do you print grade shields on the carton?<\/strong><\/p>\n

    A: We print the artwork you supply, including grade shields and plant codes. We do not create or verify regulatory content, because grade and plant codes are issued to you and vary by state.<\/p>\n

    Q: Is a printed carton much dearer than a blank one?<\/strong><\/p>\n

    A: Printing adds a plate charge per color and a small cost per unit that falls with run length. Embossing can be cheaper at low volume. We quote both so you can compare them against your yearly volume.<\/p>\n
