The United States Patent and Trademark Office has granted PulPac three new US patents, two of which concern the divisional applications from PulPac’s original applications filed in 2016/2017, where one is related to the basic process of Dry Molded Fiber, and the second is related specifically to bottle forming. The third patent concerns the layering of the cellulose web in the Dry Molded Fiber process.
“The patent related to bottle forming is especially interesting,” says Ove Larsson, Chief Innovation Officer. “We have a few viable solutions for this. One involves turning the cellulose web into a cylindric shape and then forming the bottle. Another important aspect is to form the bottles in a “seamless” continuous process. And we have filed an application for that. We seek to harness the possibilities of using rolls and a ‘forming shoulder’ to fold the web, turning it into a cylinder.”
