PP sheet is made of polypropylene resin as the main raw material, adding various process color masterbatch, toughening agent and brightening agent. It is made by mixing, plasticizing extrusion, three-roll calendering, cooling, drawing and winding. . PP sheet has the characteristics of non-toxic, odorless, hygienic, high mechanical strength and good barrier properties, and can be used for packaging in industries such as industry, agriculture and fruit. The surface of the tray made of PP anti-slip sheet is smooth and beautiful, and is well received by users. PP sheet is also suitable for the packaging of high-resistant cold foods, such as ice cream boxes, dumpling boxes, dumpling boxes and so on.
PP plastic has: environmental protection, beautiful, silk screen printing, Ke Yin, bronzing, high temperature resistance, low temperature resistance, high transparency, resistance to flexion, product compliance with food testing standards (also not required), microwave.
Disadvantages of PP: low dimensional accuracy, insufficient rigidity, poor weather resistance, easy to produce "copper damage", it has a post-shrinkage phenomenon, after demolding, easy to age, become brittle, easy to deform.
