Foam paper packaging material

The PSP company in Bremen, Germany, has developed a process for the production of foam paper. The replacement of foam with packaging materials made from foam paper can effectively reduce environmental pollution. The replacement of foam plastics by packaging materials produced by PSP can effectively reduce environmental pollution. PSP's foam paper uses old newspaper scraps and flour as raw materials. Its production process is to first cut the recycled old newspapers and newspapers into pieces, then grind them into fibrous pulp, and mix them with flour in a ratio of 2:1. The mixed pulp material is injected into the extruder into cylindrical particles. In the extrusion process, raw materials are subjected to steam as raw materials, and different shapes of packaging materials can be produced as required. Its production process is relatively simple, it can be molded at one time, eliminating multiple foaming and cooling processes, requiring no foam additives and requiring only steam. The production and use of foamed paper are all beneficial to the environment, and can be recycled and reprocessed. The production cost is 10% lower. (Hu Hongwu)
