Fiber Molded Parts for Every Need

What is Molded Fiber Packaging?

Fibre casting, also known as moulded pulp, is a sustainable material produced using a wet pressing process. This involves sucking an aqueous fibre pulp made from recycled paper or cellulose into a mould and then drying it. The result is robust, recyclable and biodegradable moulded fibre parts that are used as individual fibre shapes in a wide variety of moulded fibre packaging.

How is fibre casting or a fibre moulded part manufactured?

In fiber casting production, paper or pulp fibers are formed into stable, precisely fitting packaging components.

  • 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. Negative pressure (vacuum) causes the fibers to settle on the surface of the mold. This creates a wet raw mold (preform).
  • Pressing: During deep drawing, the wet mold 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.

What fiber casting processes are there?

There are three proven manufacturing processes that differ in terms of precision, wall thickness, and area of application:

1. Standard molded fiber casting 

  • Thick-walled (up to 11 mm) with high shock absorption
  • Ideal for robust products such as motors, household appliances, white goods
  • Most cost-effective option
  • Soft surface, less suitable for visually demanding products 

2. Post-press fiber casting 

  • Dried parts are re-shaped under pressure
  • Higher contour accuracy for automated handling
  • Less shock absorption, but more precise fit
  • Approx. 30% higher material consumption 

3. Precision fiber casting 

  • Very thin-walled parts (from 1 mm)
  • High shape accuracy and clear edges
  • Simultaneous pressing and drying in heated mold
  • Suitable for small, sensitive parts in high quantities (e.g., blister packaging)

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.

Sustainability & Recycling of Fiber-molded Inlays & Trays

Recycled paper & natural fibers

Fiberboard packaging is made from recycled material, aka waste paper, or natural fibers. This makes it resource-efficient and sustainable.

100% biodegradable

Fiber-reinforced molded parts decompose completely without releasing any harmful substances. The packaging can be easily disposed of via the paper recycling system.

Fresh fiber possible

Only recycled fibers are used for protective packaging for fiber molded parts. For special applications, white virgin fiber or a mixture of virgin and recycled fibers can be used.

Optional additives

If necessary, additives such as corrosion protection can be added to optimally adapt the packaging to specific products or transport conditions.
