What is Fiber Casting or Fiber Pulp?

Molded fiber is a material based on paper or cellulose fibers.

Fiber casting—also known as “molded pulp”—is a sustainable material produced using a wet pressing process. In this process, an aqueous fiber pulp made from recycled paper or cellulose is sucked into a mold and then dried.

The result is robust, recyclable, and biodegradable molded fiber parts that are used as individual fiber molds in a wide variety of molded fiber packaging – for example, as shock-absorbing, eco-friendly packaging solutions for electronics, cosmetics, food, or shipping products.

Fun fact: Egg packaging is one of the oldest applications for molded fiber packaging. Classic egg carton production uses the wet pressing process, as is common in fiber molding.

How does Fiber Casting Work?

Fiber casting production involves the following steps:

Pulp preparation

Waste paper or pulp is dissolved with water to form a fiber slurry (pulp). This is cleaned and, if necessary, mixed with additives (e.g., starch for stability).

Shaping

A mold with fine holes (usually made of metal, similar to a sieve) is immersed in the pulp. Vacuum pressure causes the fibers to settle on the surface of the mold, creating a wet preform.

Pressing

In plastic thermoforming, the wet preform is pressed between heated mold halves to compact it and create a smoother surface.

Drying

The still wet fiber molded parts are dried thermally or by pressing – either with hot air, infrared, UV, or contact heat.

Post-processing

The finished fiber molded packaging can optionally be trimmed, punched, printed, or impregnated, depending on the desired end product. 

Advantages & Properties of Fiber Molded Packaging

Fiber-reinforced packaging offers a number of advantages:

Fiber-reinforced trays for transport and logistics

A typical application for fiber-molded packaging is trays for transport and logistics processes—for example, for the secure storage and fixation of parts, electronic components, or medical samples. Fiber-molded trays are stackable, shock-absorbing, and can be used in both manual and automated processes.

Fiber-reinforced packaging for medical products

Fiber-molded packaging is also used in the medical sector, for example as disposable trays for surgical instruments, dental products, or diagnostic kits. Depending on the manufacturing process, these can even be sterilized, thus meeting the highest hygiene requirements—while at the same time being easily disposed of via the paper recycling system.

Fiber-reinforced molded parts as shipping packaging

Fiber castings are used in shipping packaging—for example, as protective inlays for machine parts, automotive components, or sensitive industrial electronics.

Fiber-reinforced inlays for high-quality consumer goods packaging

Another important area of application is fiber-molded inlays for packaging high-quality consumer goods. In electronics, cosmetics, and household appliance industries, attractive fiber-molded inlays are increasingly replacing conventional plastic parts. Fiber-molded packaging not only reliably protects the product, but also emphasizes the brand's commitment to sustainability.
