PP is the abbreviation of polypropylene plastic, and PP recycled material is also polypropylene recycled material. Regeneration also refers to recycling, which is a general term after the second thermoplastic treatment relative to new raw materials. After the general plastic is used once, it can be used as a raw material again after being thermally extruded and granulated by a recycling machine. The recycled and extruded polypropylene material is called PP recycled material.
