Recycled paper pulp is the most used molded pulp material in the world, and egg packaging is the reason. Made from 100% post-consumer recovered paper, its fibers have already been through several use cycles, which leaves them short at 0.8 to 1.5 mm. Short fiber is usually described as a weakness. In molded pulp it is an advantage: it flows into mold detail, drains predictably on the forming screen, and produces the most dimensionally consistent parts at the lowest cost in the range.
The characteristic gray-brown color comes from mixed recovered stock rather than from any pigment, and it varies with the incoming waste stream. For the applications this material suits, that variation is irrelevant. For anything appearance-critical, it is the reason to choose a different base.
The honest limitation is strength. Each repulping cycle shortens fibers and reduces bonding, so recycled pulp sits at the lower end of the strength range. Parts compensate through geometry rather than through fiber: ribs, cones, and curves carry load that a flat wall cannot, which is why a well-designed recycled part outperforms a poorly designed virgin one.
Egg packaging. Cartons and trays are the single largest molded pulp application worldwide and this is the material behind almost all of it. Detail reproduction, dimensional consistency, moisture regulation, and cost all align with what egg packaging needs. See boîtes à œufs en pâte moulée et molded pulp egg trays.
High volume protective inserts. Where a part ships in millions and is discarded at receiving, cost per unit governs and this material wins on it.
Parts with complex internal geometry. Counterintuitively, the cheapest fiber reproduces intricate features best, because short fibers conform where long ones bridge.
Buyers reporting post-consumer recycled content. A 100% PCR claim is simple to substantiate and increasingly appears as a procurement requirement rather than a preference.
Where recycled pulp is the wrong call: direct food contact, which needs pâte blanchie; load-critical structural parts, which need papier kraft compostable; and anything needing a pale or precisely reproduced color, which needs pâte blanchie as a base. For color work generally, see pâte colorée.
The nearest alternative is papier ondulé, which draws from recovered board specifically rather than mixed paper. OCC gives more strength and a browner tone; mixed recycled gives finer detail.

Les produits en pâte moulée remplacent le plastique et la mousse et offrent des options recyclables et biodégradables. Des formes, des couleurs et des surfaces écologiques personnalisées sont disponibles. Nous fournissons des emballages abordables et durables grâce à un service de prototypage et de fabrication en interne.
Les plateaux de pulpe de papier pour le pressage à sec, fabriqués à partir de matériaux recyclés 100%, offrent une alternative écologique et rentable au plastique. Ils sont amortissants, résistants à la température et empilables, ce qui permet de gagner jusqu'à 20% d'espace.
Bonitopak propose de la pâte à papier moulée en six couleurs, dont le blanc, le naturel et le noir, avec une précision chromatique de 95%. Des méthodes écologiques garantissent un blanchiment sûr. Le naturel et le blanc conviennent le mieux aux aliments ; les autres conviennent à l'emballage des plateaux.
