In modern industry and daily life, there is a material that seems unremarkable yet plays a pivotal role — barrier film. Like a silent invisible guardian, it relies on its special properties to protect the quality and shelf life of numerous products. As the name suggests, a barrier film is a type of

The main component of thermosetting plastics is linear or branched low-molecular-weight polymers, with reactive functional groups on the molecular chains. Therefore, during the heat-induced molding process, thermosetting plastics undergo not only physical state changes but also irreversible chemical

Application Fields of Polyester Film I. Introduction to Polyester Film Polyester film, also known as PET film (including optical sheets, polyester film, photosensitive paper, Mylar, benzo-tin film, cellophane, and release film), is a film material made from polyethylene terephthalate (PET). It i

To solve the above problems, it is essential to understand the specific causes of static electricity generation in films. In summary, the main reasons for static electricity in films are as follows: 1. Static Electricity Generated During Film Production Static electricity arises during film product

Due to the inevitable friction of the film, static electricity affects production in the following main aspects: 1. Printing DifficultiesDue to(micro-static discharge), burrs or flocculent (whisker-like) ink often escapes along the edges of printed patterns. Static electricity charges the ink, caus
