At present, PE stretch film is widely used in the logistics industry and is a convenient and environmentally friendly packaging material. PE stretch film has a wide range of uses, and can also be used for damage protection and purification during food packaging, maintenance, transportation, storage, processing and application.
pe stretch film production materials:
1. The pe stretched film is made by co-extruding polypropylene particles into a sheet, which is then stretched in the longitudinal and transverse directions. The transparency of polyethylene decreases with increasing crystallinity. Under a certain degree of crystallinity, transparency increases with increasing molecular weight. The melting point of high-density polyethylene is 132-135°C, while the melting point of low-density polyethylene is lower (112°C) and the scale is wider.
2. PE stretched film is a kind of stretched film made of polyethylene terephthalate as raw material, made into thick sheet by extrusion method, and then biaxially stretched. It is a colorless, bright and glossy stretch film with excellent mechanical functions, high rigidity, high hardness, high toughness, friction resistance, puncture resistance and low temperature resistance. It has excellent chemical resistance, oil resistance, air tightness and nasal spray protection, and is one of the commonly used barrier composite stretch film substrates.
3. PE stretch film material is added with high-quality tackifier, heated, extruded, cast, and then cooled by chill roll. It has the advantages of glass, food, toughness, heat resistance, pressure resistance, cold resistance, tear resistance, high viscosity, thin thickness, and high elasticity. It can save materials, rest and time when used, and is widely used in glass, food, paper, building materials, logistics, chemicals, plastic materials, etc.
PE stretch film is a semi-transparent, shiny, soft stretch film with excellent chemical volatility, heat sealability, water resistance and moisture resistance, and rare is transparent. PE stretch film is characterized by strong stretching function, good elasticity, environmental protection, and harmless to the environment.
