Moulded Pulp Packaging for Sustainable and Protective Solutions

What is Moulded Pulp Packaging?

Moulded Pulp Packaging, also named moulded pulp or moulded fiber, is a packaging material, typically made from recycled paperboard and /or newsprint. It is used for protective packaging or for food service trays and beverage carriers. Other typical uses are end caps, trays, plates, bowls, and clamshell containers.

Benefits of Moulded Fiber Packaging

  • Provide product protection in shipments
  • Customer convenience
  • Economic packaging
  • Environmental benefits.
  • Certified IMFA members provide molded fiber packaging design services and prototypes with cost estimates based on customer requirements.
  • Molded fiber products, manufactured with waste paper or other natural fibers (which are essentially cellulose), are recyclable along with other waste paper and are biodegradable and compostable where facilities are available.
  • Both fiber & water are recycled and reused in manufacturing, resulting in almost zero waste.
  • There are no toxic or hazardous waste materials expelled into the environment
  • Packaging of non-fragile, heavier items, as well as plant, floral, and nursery pots and containers.

Types of Molded Fiber Products

Type 1- Thick wall- Manufactured using a single mold with product wall thickness from about 5mm to 10mm (3/16 to3/8 inches). One surface is relatively smooth, while the other is rough.
Type 2- Transfer molded- Manufactured using one forming mold and one transfer mold with product wall thickness from 3mm to 5mm (1/8 to 3/16 inches).
Type3- Thermoformed (Thin wall)- Manufactured using multiple heated molds with product wall thickness of about 2mm to 4mm (3/32 to 5/32). Surfaces are smooth, and forms are well-detailed with minimal draft angles. Products are dried in the mold, and no oven curing is needed. Due to the hot mold pressing process, the walls are somewhat denser, and thermoformed plastic material is used.
Type 4- Processed Molded Fiber Products– This type refers to molded fiber products that require some type of secondary or special treatment other than simply being molded and cured.
Hot or after-pressed – die cut or perforated- printed- colored- special mold.
Special slurry formulations, embossments, special design features, and special additives.

What designs are possible with molded pulp?

Molded pulp can be designed into trays, clamshells, inserts, and custom shapes for protective, retail, and industrial packaging applications.

Molded pulp packaging is best suited for medium to high production volumes, where tooling costs are justified, and unit cost becomes economical.

Dust can be present in molded pulp packaging, but it is minimal in high-quality production and can be controlled with proper finishing and processing.

Moulded pulp packaging offers good weight-bearing strength for light to medium loads, depending on design, thickness, and structure.

Yes, molded pulp packaging is well-suited for cushioning applications, providing effective shock absorption and protection for fragile items.
Molded pulp packaging offers cost advantages through low material cost, reduced waste, efficient production at scale, and lower shipping costs due to its lightweight design.
Order quantities typically depend on tooling and production, but moulded pulp packaging is most economical at medium to high volumes.

Yes, moulded pulp packaging is commonly used to produce both egg trays and wine bottle protective packs.

Tooling costs for moulded pulp packaging vary based on design complexity and size, but they are typically a one-time investment for custom moulds.
