Analyze the quality requirements from the use of PET release film-film supplier

With the development of market demand, the demand for PET film and PET release film in industrial production is increasing. There are more and more companies producing PET film and PET release film in China, and the market is transparent. There is not much to say about PET film, after all, it is not required for special use. Domestic technology basically meets conventional use, and the quality gap is not big. Here I will tell you about PET release film. I believe that many purchasing friends have asked many companies about the unit price. The price of PET release film often differs greatly in price. Many friends here are very strange. In fact, this point needs to be analyzed from the use of PET release film. The gap between ordinary isolation film and optical grade PET release film is very large. In fact, PET release film is basically a kind of industrial consumables, and rarely appears on the product. The main common uses are as follows: 1. Substrate in the label and tape industry. 2. Tape application for tape casting of polymer materials, such as microelectronic components. 3. Photoelectric die-cutting and punching industry applications. 4. Application of lamination process in various multilayer printed circuit board industries. 5. Production and application of cover film and pure adhesive film. 6. Application of PCB/PCL. From the difference in process, we can see that various situations have different effects on PET release film. The quality requirements are also different. For example, ordinary die-cutting and punching require PET release film for uniform thickness and stable peeling force. The optoelectronic industry has more requirements for transparency and temperature resistance on the basis of the peeling force. In addition to temperature resistance, some polymer materials must also consider the corrosion resistance of chemical reagents, the stability of silicone oil, and the non-reaction with other chemical products. It is precisely because of the different technological processes in various industries that the quality requirements for PET release films are also different. Ordinary PET release film only needs to use ordinary PET film, and the photoelectric industry needs to use optical grade PET film as the substrate. The coating process is much more precise than the ordinary PET release film coating process, and the requirements for equipment are also higher. As a result, the price of optical grade PET release film is much higher than that of ordinary PET release film. It is a company specializing in the production of PET film with multiple functions, such as: transparent PET film, milky white PET film, release PET film, supply of PET motor film, etc. With a wide variety of products, affordable prices, and environmental protection, we provide customers with excellent quality and service based on the service tenet of excellence in production, honesty and trustworthiness in distribution, and warm and thoughtful service, and the spirit of assisting partners to achieve their own careers.
