PP sheet is made of polypropylene resin as the main raw material, added with various process color masterbatches, toughening agents and brighteners, and is made by mixing, plasticizing extrusion, three-roll calendering, cooling, traction and winding. . PP sheet has the characteristics of non-toxic, odorless, hygienic, high mechanical strength and good barrier properties. It can be used for packaging in industry, agriculture, fruit and other industries. The surface of the tray made of PP non-slip sheet is smooth and beautiful, which is welcomed by users.
