4 Types of Molded Pulp Every Brand Should Understand Before 2026

In 2024, the packing business reached a crossroad. Molded pulp packaging in the world market was valued at 5.1 billion dollars and forecasts indicate that the value is going to grow in the next decade. Large technology firms took radical steps to drop plastic materials.

By the end of 2024, Apple had cleared 100 per cent of packaging plastic, and Samsung had released Galaxy S24 with all-recycled moulded pulp trays. These were not single-handed actions. Studies show that 77 percent of consumers in the United Kingdom currently expect businesses to provide environmentally friendly packaging, and almost half of the consumers are willing to pay high prices to businesses that have packaged their products responsibly.

Companies are under increasing pressure from regulatory authorities across the globe. At present, 91 percent of all packaging wastes are discarded either in landfills or in nature. This fact is the reason behind the transition towards biodegradable solutions such as the use of molded pulp packages.

What Actually is Molded Pulp Packaging?

Recycled paper, cardboard, or natural fibers are used to create protective packaging by molded pulp through the use of water. It begins with the mixing of water and raw materials in order to form fiber slurry. This mixture is forced through mesh molds by the vacuum forming until the correct thickness is achieved.

Examples of materials used are sugarcane bagasse, bamboo fiber, wheat straw and recycled corrugated cardboard. The surfaces are usually coarse on one side and medium smooth on the other side. Production involves three dimensional forms with rounded edges as opposed to knife edges.

Under prime composting conditions, it is natural that products break down within 90-180 days to biodegrade. The fact that it is recyclable implies that once used, molded pulp will fit perfectly in the already established paper recycling systems.

Breaking Down the 4 Types of Molded Pulp Manufacturing

The International Molded Fiber Association identifies four distinct categories based on manufacturing processes. Each type serves specific applications with unique characteristics. Understanding these differences helps brands select appropriate packaging solutions.

Wall thickness varies significantly between types, ranging from 0.7mm for premium finishes to 6.0mm for heavy-duty protection. Surface quality, production speed, and cost factors differ across all four classifications. Smart selection depends on matching product requirements with packaging capabilities.

Type 1 Thick-Walled Delivers Industrial Strength

Thick-walled molded pulp uses relatively inexpensive single-pass molds with mixed recovered paper and kraft paper slurries. Wall thickness reaches 2.5mm to 6.0mm, providing robust cushioning for heavy products. One surface appears moderately smooth while the opposite side stays very rough.

Manufacturing costs stay low because production relies on basic equipment and recycled materials. The rough texture limits use in consumer-facing applications. However, strength and affordability make this type ideal for shipping furniture components, automotive parts, and industrial equipment.

Major applications include corner protectors, edge guards, and pallet supports. Companies prioritize function over appearance for these protective elements.

Type 2 Transfer Molded Dominates Current Markets

Transfer molded represents the dominant segment in the global molded pulp industry. The process uses vacuum forming and transfer molds with extremely fine wire mesh shaped like the exposed surface. Wall thickness ranges between 1.5mm and 3.0mm.

Very high-capacity, high-speed transfer molding equipment produces drink trays, cup carriers, wine shippers, egg cartons, egg trays, and fruit containers. The fibrous slurries frequently contain high percentages of recycled newspaper, creating relatively smooth surfaces on both sides with good accuracy.

Production speed makes transfer molded pulp cost-effective for moderate to high-volume applications. Electronics companies package cellular phones and household items using this type. The proven track record spans over 100 years protecting fragile eggs during transport.

Type 3 Thermoformed Represents Premium Quality

Thermoformed molded pulp uses cure-in-the-mold technology producing well-defined, smooth-surfaced products. Wall thickness measures just 0.7mm to 1.2mm. After forming, heated molds capture and densify the product while still wet.

Products eject from heated molds in finished state as opposed to being dried in heated ovens. Both surfaces emerge remarkably smooth with appearance resembling plastic materials. This premium finish appeals to luxury brands requiring refined aesthetics.

Apple’s Beats Studio Pro headphones use thermoformed molded pulp made from bagasse and bamboo fiber. The Vision Pro features molded pulp inserts supporting the company’s plastic elimination goals. The thermoformed fiber segment projects significant revenue growth with a 6.1% annual increase through coming years.

Cosmetic brands, wine producers, and electronics manufacturers choose wet pressing molded pulp for products where presentation matters. Custom colors achieve 95% Pantone matching accuracy while maintaining environmental responsibility.

Type 4 Processed Adds Custom Finishing Options

Processed molded pulp undergoes secondary processing different from or in addition to basic production procedures. This applies to any of the first three types. Secondary treatments include coating, printing, hot-pressing, die-cutting, trimming, or adding special slurry additives for custom colors.

Coating applications improve water resistance for specific food service needs. Hot pressing creates smoother surfaces when required. Digital printing and embossing add branding elements directly onto packaging surfaces. Color additives produce custom shades matching brand guidelines.

The flexibility expands application possibilities significantly beyond standard offerings. Brands requiring specific aesthetic qualities or functional properties benefit from processed variations. Custom molded pulp packaging solutions help companies differentiate products while maintaining sustainability commitments.
