Germany Develops New Foam Paper Packaging Materials

The PSP company in Bremen, Germany, has developed a foam paper production process. The replacement of foam with packaging materials made from foam paper can effectively reduce environmental pollution.
The PSP company's shredded paper uses raw newspaper scraps and fabrics as raw materials. The production process is to first cut the recycled old newspapers and newspapers into pieces, then grind them into fibrous pulp, mix them with the fabric in a ratio of 2:1, and mix the pulp materials into an extruder and press them into cylindrical particles. During the extrusion process, the raw material is foamed by the action of water vapor to form a foam paper. Using foam paper pellets as raw materials, different shapes of packaging materials can be produced as required.
Compared with foam plastics, foam paper has a relatively simple production process and can be molded at one time, eliminating the need for multiple foaming and cooling processes. Bubble foam does not require chemical additives, only water vapor. Both the production and use of foam paper have environmentally beneficial properties. It can be handled like ordinary waste. Used foam paper can also be recycled and reprocessed. From the economic point of view, producing the same amount of packaging materials, foam paper is 10% cheaper than foam.
Foam paper has great application prospects. It can not only be used as packaging material, but also can open insulating materials and building materials.
