What is pe stretch film material

The main material of PE stretch film is PE, which is recycled first grade material, still can be blown film, used for non-food and pharmaceutical packaging, PE stretch film does not produce moisture in the process nor does it stick to the sealing bar, easy maintenance and operation, high toughness, smoothness and anti-rubbing make it suitable for high-speed production line automatic packaging.

PE stretch film is made of thick sheet by extrusion method, and then made of stretch film material by biaxial stretching. It is a colorless, transparent, glossy stretch film with excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, friction resistance, high and low temperature resistance. Chemical resistance, oil resistance, air tightness and good fragrance retention, is one of the commonly used permeability barrier composite stretch film substrates.

Pe stretch film is made from polypropylene particles by co-extrusion to form a sheet, and then by stretching in both directions, due to stretching molecular orientation, the transparency of polyethylene increases with crystallinity and decreases under a certain degree of crystallinity, transparency increases with molecular weight. The melting point of high-density polyethylene ranges from 132-135oC, while the melting point of low-density polyethylene is lower (112oC) and wider.

PE stretch film material with adhesion enhancer, then by heating, extrusion, cast, PE stretch film by cooling roller cooling and become. It has the advantages of strong toughness, high elasticity, anti-tear, high viscosity, thin thickness, cold resistance, heat resistance, pressure resistance, etc. It can save materials, labor and time when used.
