The structural parts of the EPP foam polypropylene material came into being. Polypropylene resin has the characteristics of light quality, rich material origin, high functional price ratio, excellent heat resistance, chemical corrosion resistance, and easy recovery. It is the fastest -growing general thermoplastic resin in the world. The industry's discussion and development of polypropylene bubbles has also become a hot spot in recent years.

At present, EPP is a green packaging material for developed countries and is used as a green packaging material replacing the foam polystyrene. ) Taking PP as the primary material, foaming technology is made of physical foaming technology. The first is used for mold sintering and forming a variety of shapes and standards for use on different occasions.
