4.5um copper plated PET film has excellent mechanical properties

Time：2023-02-18Number：1032

From a global perspective, the main production areas of PET film are Japan, South Korea, Taiwan, etc., while China is becoming the world's largest electronic terminal product and device processing and manufacturing base, as well as the country and region with the highest demand for this product. Japan, South Korea, and other countries have been conducting research on PET films for a long time and have mastered the complete set of core technologies for product production, almost monopolizing the global high-end market. However, domestic enterprises have relatively insufficient capabilities in researching and producing high-end PET films, and currently rely mainly on imports for high-end products.
pet filmIt is a packaging film with comprehensive performance. It has good transparency and luster; Has good air tightness and fragrance retention; Moderate moisture resistance, with a decrease in moisture permeability at low temperatures. PET film has excellent mechanical properties, and its strength and toughness are the best among all thermoplastic plastics. Its tensile strength and impact strength are much higher than ordinary films.
According to the continuous updates and iterations in the market,pet filmThe development of polyester film for fluorine free solar cell backsheet can achieve the functions of traditional polyester film for fluorine free solar cell backsheet, while also having excellent chemical corrosion resistance and good electrical performance. Its electrical insulation is not affected by temperature, stable chemical performance, good electrical insulation and radiation resistance make it possible to provide good protection for fluorine free solar cell backsheet, with huge market prospects. At present, the reinforced PET film material has been supplied to customers in bulk, and it will become one of the growth points of the company's new business in the future with the commissioning of the new production line. 1631453972(1).jpg

PET is a plastic material, scientifically known as polyester. Polyethylene terephthalate, chemical formula COC6H4COOCH2CH2O. Source in English: Polyethylene terephthalate。 As a protective film, it is a thin film with certain functions that differs from the base film and PET original film. Therefore, the secondary processing and coating of adhesive on the substrate of PET film is the key. According to different types of adhesives, PET protective films can be classified into PET silicone protective film, PU adhesive protective film, and acrylic adhesive PET protective film.
