The Main Uses of PET Release Film
PET release film is made by coating a thin and uniform release agent on the surface of the PET substrate. PET release film has excellent high-temperature resistance function. Its physical characteristics are: smooth appearance, no particles, no bubbles, no wrinkles, etc. It is very suitable for processing various materials. Next, some of the main uses of PET release film materials were introduced.
1. Mobile occupation
Many links in the mobile phone production industry chain are inseparable from PET release film materials, such as OCA optical adhesives used for screen structures.
2. Die-cutting profession
3. Adhesive Products Occupation
4. Printed Circuit Board Occupation
5. Packaging profession
6. Screen printing profession
7. Thin film switch production
8. Flexible circuit
The classification of release films can be divided into different substrates: PE release film, PET release film, OPP release film, composite release film (i.e. the substrate is composed of two or more raw materials), etc.
According to the release force, it can be divided into light release film, medium release film, and heavy release film. According to color, PET release films can be divided into various colors such as red release film, yellow release film, green release film, blue release film, etc. According to surface treatment, it can be divided into: single-sided release film, double-sided release film, silicon-free release film, fluoroplastic release film, single-sided corona, double-sided corona, frosted release film, matte release film, etc.
Single sided release film: HDPE (low pressure polyethylene) release film, used for sealing LDPE (high pressure polyethylene) release films such as waterproof tapes. BOPP (stretch polypropylene) release films for mechanical product packaging, Hot-melt adhesive packaging, health care products (diapers), anti-corrosion coiled materials, etc. are used for PET (stretch polyester) release films such as sealing tape, silent tape, etc. Double sided release film for adhesive maintenance, red/green polyolefin (PE).
Double sided release film: used for transparent PET double-sided release film with foam tape; Double-sided tape anti sun isolation film (HDPE silver coating film); Reinforced aluminum plated base material BOPP reinforced (BOPET) for waterproofing, sun protection, and cooling.
Improve the adhesion of the aluminum coating and make it resistant to 100 ℃ cooking. According to raw materials and purposes, it can be divided into: silicone oil film/release film - polyester film (PET) maintenance film production, Polyester film, pre coated film, light dispersion film, color inkjet film (computer film), electronic professional printing film, matte film, drawing film, white polyester film, black polyester film, PET/polyester film/PET Mylar.
