????Today we will analyze and compare PET film and PVC film. ? ????PET film, which is a kind of polyethylene terephthalate plastic, which roughly includes polyethylene terephthalate (PET) and polybutylene terephthalate (PBT). The internal molecular structure of PET is highly symmetrical, and it has a certain degree of crystal orientation, so it has high film-forming and forming properties. PET has good optical properties and weather resistance, and amorphous PET has good optical transparency. In addition, it also has excellent wear resistance friction and dimensional stability and electrical insulation. Bottles made of PET have the advantages of high strength, good transparency, non-toxicity, anti-permeation, light weight, high production efficiency and so on, so they have been widely used. ????The main uses of PET film are: film sheets; various types of food, drugs, non-toxic and sterile packaging materials; high-end packaging materials for textiles, precision instruments, electrical components; audio tapes, video tapes, movie films, computer floppy disks, Base materials for metal coatings and photosensitive films, etc .; electrical insulation materials, capacitor films, flexible printed circuit boards, membrane switches and other electronic and mechanical fields. ? ????The full name of PVC is Polyvinyl Chloride (polyvinyl chloride), it is a synthetic material, the main component is polyvinyl chloride, and other ingredients (such as anti-aging agents, modifiers, etc.) are added to enhance its heat resistance And its ductility and ductility. The essence of PVC film is a vacuum blister film. Its top layer is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. PVC film is currently mainly used for surface packaging of various panels.
