The role and use of PET film-technical knowledge
The role and use of PET film source: protective film factory direct sales release time: 2019-03-01 click: 2983 PET film is a kind of plastic film, PET film is a kind of transparent and glossy film, but also has a good Air tightness and fragrance retention. General PET film can be divided into: high-gloss film, reflective film, coating film and antistatic film, etc., according to different needs can choose to purchase different films. PET film has excellent high temperature resistance characteristics, so it is widely used in die-cutting and adhesive products. Generally, PET film is used as the substrate, and then a layer of film release agent is evenly coated on one side or both sides. The surface of the PET cladding is flat and smooth, without wrinkles, particles, bubbles and other defects. It has excellent physical properties, and has a small thickness tolerance, low thermal shrinkage, and has good tensile strength, tensile resistance, and chemical inertness. PET release film is generally used to isolate viscous materials, and is widely used in industries such as electronics, inkjet consumables, reflective materials, tapes, and self-adhesive waterproof membranes. Product thickness: 0.019mm, 0.025mm, 0.036mm, 0.05mm, 0.075mm, 0.1mm, 0.125mm, 0.175mm, 0.188mm Release force is controllable, high gloss, cleanliness, high residual adhesion, 92%, good surface performance . The characteristics of PET film when compounded with adhesive products: 1) There is no migration phenomenon, which eliminates the risk of the silicone resin release film being transferred to the material it is attached to. 2) The weight per unit area of u200bu200bthe single-sided or double-sided coating of the PET film The difference is small. 3) High stability under extreme weather conditions. 4) Very long shelf life. 5) The base film has excellent mechanical strength and chemical properties. 6) High temperature resistance can reach 180°C for a long time, and 200°C within 10 minutes.
