PulPac has just announced the filing of an additional patent application, further refining its pioneering cellulose forming technology for competitive fiber-based packaging and single-use products. 

The new patent application comprises a hybrid tool that uses the pressing force to work in mould parts both in a pressing direction and in a lateral direction. The hybrid tool efficiently uses one pressing stroke for manufacturing a product having a general form in the pressing direction and a special feature such as for example undercut in the lateral direction. This is especially advantageous when manufacturing products like lids and other applications where e.g. stacking and denesting features are important. The hybrid tool also brings possibility of enhanced surface quality and improved tool life.

About Dry Molded Fiber
Dry Molded Fiber, invented and patented by PulPac, is a manufacturing technology designed for the circular economy – using renewable pulp and cellulose resources to produce low cost, high performance, fiber-based packaging, and single-use products. Dry Molded Fiber gives up to 80-90% lower CO2 footprint at similar cost as plastic. It is up to ten times as efficient as conventional fiber molding invented over 100 years ago. The dry process also saves massive amounts of valuable water resources. In addition, energy savings are significant - as the molded products need no drying.
