Nowadays, PE stretch film is the most widely used in the logistics industry. It is a convenient and environmentally friendly packaging material. The use of PE stretch film is very common. It can also be used in food packaging, protection of products in transportation, storage, and processing. , Avoid damage during use. So what materials are made of PE stretch film?

 

1. PE stretch film is made by co-extrusion of polypropylene particles to form a sheet, and then stretched in two deflection directions. Because of the orientation of the stretched molecules, the transparency of polyethylene decreases with the addition of crystallinity. Under a certain degree of crystallinity, the transparency increases as the molecular weight increases. High-density polyethylene has a melting point scale of 132-135°C, while low-density polyethylene has a lower melting point (112°C) and a wide range.

 

2. PE stretch film is made of polyethylene terephthalate as raw material, which is made into thick sheet by extrusion method, and then stretched film material made by biaxial stretching. It is a colorless, transparent, glossy stretch film with excellent mechanical functions, high rigidity, hardness and toughness, friction resistance, puncture resistance, and low temperature and low temperature resistance. It has excellent chemical resistance, oil resistance, air tightness and nasal spray protection. It is one of the commonly used barrier composite stretch film substrates.

 

3. PE stretch film materials are mixed with high-quality tackifiers, heated, squeezed, cast, and then cooled by chill rolls. It has the advantages of glass, food, strong toughness, heat resistance, pressure resistance, cold resistance, tear resistance, high viscosity, thin thickness, and high elasticity. It can save materials, save rest, save time when used, and is widely used in glass. , Food, paper, building materials, logistics, chemicals, plastic materials, etc.

 

PE stretch film is a kind of translucent, shiny and soft texture stretch film. It has excellent chemical fluctuation, heat sealability, water resistance and moisture resistance. It is rare that it is transparent and has the characteristics of pe stretch film. It has strong stretching function, elasticity, environmental protection, non-toxicity and no pollution to the environment.
