Packaging capabilities - How does it work?

Molded fiber is a classic packaging medium that continues to be used in new and innovative ways. It is economical and environmentally friendly. It has the ability to protect products and to promote their integrity, freshness and appearance.

Production process

The term ‘molded fiber' describes the production process where up to 100% recycled paper is dissolved in water to form a homogeneous fiber mixture. This mixture is pumped into a vat containing a large revolving drum. Precision designed packaging moulds are mounted onto the drum. The liquid pulp is sucked into the moulds by means of a vacuum and water is simultaneously extracted. The wet packaging is then pressed and dried, all in a continuous forming and drying process. Egg cartons subsequently are after-pressed and printed or labelled. Machines used for this process work with a closed water system, in which the water is cleaned and used again.
By changing the shape and size of the tools, different packaging solutions can easily be produced.

• The conveyor belt¹ leads the recycled paper to the pulper².
• Water from the water tank³ and recycled paper are processed into pulp and pumped into the 4% pulp tank⁴
• The pulp is pumped through an automatic cleaning system⁵ and consistency regulator into the 1% pulp tank^6.
• The pulp is pumped into the moulding machine⁷ where products are formed on moulds using vacuum. The hot air hood⁸ reduces the water contents of the products.
• he moulded products are blown off on carriers, guided by the intermediate frame⁹. The carriers take the products through a multi-layer oven¹⁰. After drying, the products are deposited on a finished product conveyor.
• Circulated air is reheated in the airheater¹¹. Exhaust air is reused to heat up the process water in the heat exchanger¹².
