PP Blister Sheet Molding Characteristics

PP sheet is made of polypropylene resin as the main raw material, adding various process color masterbatches, toughening agents and brightening agents, and is made by mixing, plasticizing extrusion, three-roll calendering, cooling, traction, and winding.

PP sheet has the characteristics of non-toxic, tasteless, 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-skid sheet is smooth and beautiful, which is very popular among users. PP sheet is also suitable for packaging of highly cold-resistant frozen foods, such as ice cream boxes, dumpling boxes, glutinous rice balls boxes, etc. PP blister has: environmental protection, beautiful appearance, silk screen printing, ke printing, hot stamping, high temperature resistance, low temperature resistance, high transparency, flexion resistance, products that meet food testing standards (or not required), and can be microwaved.

Disadvantages of PP Sheet: low dimensional accuracy, insufficient rigidity, poor weather resistance, easy to produce "copper damage", it has post-shrinkage phenomenon, after demolding, it is easy to age, become brittle, and easy to deform.
