PET/PE is compounded by laminating PE PET/PE film lamination is a common packaging material production process. By laminating PET film and PE film, packaging materials with excellent performance can be obtained. Below we will introduce in detail the process and characteristics of PET/PE laminating lamination. PET, full name polyethylene terephthalate, is a high-performance plastic widely used in the packaging industry. It has excellent transparency, mechanical properties and high temperature resistance, as well as good chemical stability and antioxidant properties. PE, full name polyethylene, is a low-density polymer with good softness and ductility, as well as good low-temperature resistance and corrosion resistance. PET/PE film lamination combines the characteristics of these two materials, making the composite film have the respective advantages of PET and PE.
