To enable themselves to achieve greater breakthroughs in products. Therefore, in the production process of PET film, not only requires a strict production environment, but also requires strict testing standards, so how do PET film manufacturers test it?

     First of all, they measured the tensile peel strength of the left and right sides of a film (a roll) to meet the customer's adhesive force requirements, and then visually observed whether the PET film had any abnormal conditions such as coating leakage and white spots, and tested whether the PET film degumming again. The whole detection process was very strict. If there is a little negligence, it may lead to damage or pollution of customer products, so PET film manufacturers will spend some manpower and material resources on product testing to ensure the quality of each product.
