Develops a new process for foam packaging paper

PSP, a German company, recently developed a new process for the production of foam paper. The packaging materials produced by it can replace foam.
The foam paper uses old books scrap paper and flour as raw materials. The old newspapers are first cut into shreds, then ground into fibrous pulp, and mixed with flour in a ratio of 2-1. The mixed pulp stock Into the extrusion press into cylindrical particles. During the extrusion process, the raw material is subjected to steam as a foam paper. Using this type of foamed paper pellet as raw material, various shapes of plastic packaging can be produced according to different needs. Foam paper can be molded once, without chemical additives, and can be recycled after use.
