PulPac has announced further patent grants for its cellulose forming technology that makes it possible to replace single-use plastics with fiber-based alternatives. The company's most general patent, that already has been granted in big parts of the world, is now also granted in Colombia. A new patent comprising hole punching of dry molded fiber (DMF) products also has been granted in Sweden.
The Colombia patent fortifies PulPac’s global ownership of the core technology of DMF. The patent relates to a method, apparatus and product where air-formed cellulose is pressed in a forming mold within given temperature and pressure intervals and has already been granted on important markets such as China, Europe, USA, Japan and Russia.
