The PET optical film substrate should be smooth and defect-free, with high gloss and light transmittance, low haze, and good coating performance. However, if the surface of the substrate is flat and defect-free, there are fewer active points in contact between the coating and the surface of the film substrate, which makes it difficult for the coating liquid to penetrate and form adsorption with it; if the substrate gloss and light transmittance are high , The surface roughness of the substrate is low, resulting in fewer bonding points between the coating liquid and the surface of the film substrate. At the same time, the PET polyester film has its own characteristics, such as the highly oriented crystals on the surface of the PET film, which makes it difficult for the coating molecules to penetrate into the PET film, and it is also difficult to form a good interface adhesion with the coating. 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.
