PET release film, also known as isolation film or separation film, there are various names. PET release film is a surface coating of silicon release agent and fluorine release agent plasma treatment on PET substrate, which has extremely light and stable release force on different organic pressure sensitive adhesives during the process. The product has good physical properties and low thermal shrinkage rate, and can be divided into light release film, medium release film, heavy release film, etc. So what are the characteristics of PET release film and where is it applied?

PET release film has high transparency (high transmittance in the range of ultraviolet to infrared), excellent heat resistance, excellent electrical properties, drug resistance (the best among transparent resins), low density, good safety processing, and excellent safety.

At present, PET release films are widely used in packaging, printing, screen printing, circuit boards, pharmaceuticals, and other fields. Transfer printing: Due to the excellent physical and mechanical properties and thermal stability of PET release films, they are currently widely used in transfer printing engineering. Transfer film, also known as transport film, is reusable and has characteristics such as good compatibility, low cost, and Luther environmental protection. In the printing field, the process involves applying a film release agent first, applying glue, and then adding it to objects made of glass, metal, and other materials.

Packaging decoration: Place the PET release film in a vacuum aluminum plating machine for aluminum plating, glue it onto paper, and then peel off the PET release film. Aluminum molecules adhere to the surface through degradation, forming the so-called aluminum plated cardboard. It has the characteristic of easy degradation and is a highly utilized and novel industrial material in recent years.

At the same time, PET release film can also be made into reflective film and protective film. Reflective film is applied to billboards, traffic reflective signs, reflective police uniforms, etc. Protective films are applied to panel protection, optoelectronic film cutting, electronic film cutting, etc.PET release filmThere are many industries involved, and the quality requirements vary greatly. With the development of the mobile phone, backlight, and home appliance industries, as well as the electronics industry, the demand for high-end release films will continue to grow. Therefore, manufacturers of release films should also adjust their formulas and improve control standards according to industry needs to meet the demand.
