Packaging capabilities - How does it work?
Moulded fibre 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.
The term ‘moulded fibre' describes the production process where up to 100% recycled paper is dissolved in water to form a homogeneous fibre 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 tank6.
- 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.
