Focus on Circulation and Efficiency, Functional PET Film Unlocks New Scenarios in Display, New Energy and Other Fields

PET FILM Product Details

PET FILM (Polyethylene Terephthalate Film) is polymerized from PTA (Purified Terephthalic Acid) and EG (Ethylene Glycol) under the action of heating, catalysts and stabilizers. It is made through multiple precision processes such as raw material drying, melt extrusion, casting, stretching and winding. As a functional film material with comprehensive performance and wide application, it is known as the "universal substrate for packaging and electronic industry". With its excellent comprehensive performance, it has penetrated into many core fields such as display, new energy, packaging and transportation. With the advancement of technology, the product is moving towards high-end, functional and green development, meeting the increasingly diversified and strict application requirements of various industries.
The core advantages of PET FILM lie in its excellent mechanical properties, chemical stability and processability. It has high tensile strength, good toughness and wear resistance, and is not easy to break or deform during use. At the same time, it has good resistance to water, oil, acid and alkali, and can maintain stable performance in various harsh environments. In addition, PET FILM is easy to process, and can be further processed through coating, printing, laminating and other processes to realize multi-functional integration, which greatly expands its application scope.
