PulPac declares 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 mold parts both in a pressing direction and 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 unique feature such as an 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 essential. The hybrid tool also brings the possibility of enhanced surface quality and improved tool life.
“Innovation is a core function at PulPac. It is at our heart how we drive change for a sustainable future with our clients. This patent application is a good example of 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 a low cost.
