PulPac files patent for tool that improves functionality for dry molded fiber

PulPac has 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.
“Innovation is a core function at PulPac. It is at our heart and how we drive change for a sustainable future together with our clients. This patent application is a good example on how we continuously can refine and make Dry Molded Fiber even more effective or adapt it to specific demands or product applications” says Peter Ekwall, IP Manager at PulPac

Dry Molded Fiber is a fiber forming technology that can replace single-use plastic with sustainable fiber-based alternatives at low cost.
