What Are the Uses of PET Release Film?

PET release film is a material commonly used in heat transfer printing. Its substrate is PET, which is coated with silicone oil, so it is generally also called silicone oil film. The conventional thickness ranges from 25um to 150um. There are two types of products: cold and hot tearing, as well as smooth and matte surface. After anti-static and scratch resistant treatment, the product has good adsorption and adhesion. This is also one of the differences between PET protective film and PET release film. The characteristics of PET release film: PET release film has high transparency, non-toxic and odorless, high tensile strength, good stiffness, anti cracking, not easily damaged, excellent electrical and optical properties, good oxygen and moisture resistance, cold resistance, and resistance

PET release film a material commonly used in heat transfer printing, and its substrate is PET, which is coated with silicone oil, so it is generally called a silicone oil film. The conventional thickness ranges from 25um to 150um. There are two types of products: cold and hot tearing, as well as smooth and matte surface. After anti-static and scratch resistant treatment, the product has good adsorption and adhesion. This is also one of the differences between PET protective film and PET release film.

Characteristics of PET release film:

PET release film has high transparency, non-toxic and odorless, high tensile strength, good stiffness, anti cracking, not easily damaged, excellent electrical and optical properties, good oxygen and moisture resistance, cold resistance, heat resistance, and excellent characteristics of corrosion resistance and stable shrinkage.

The purpose of PET release film:

PET release film is mainly used in electrical, insulation, packaging, magnet containers, films, tapes, floppy disks, movies, video and entertainment software, etc; It has a wide range of applications, such as hot stamping film, aluminum plating film, printing film, packaging film, packaging materials, composite materials, laser anti-counterfeiting composite film, drawing paper, electrical insulation materials, and capacitors.

The purpose of various release membranes:

1. PET reflective film: applied to billboards with reflective requirements, traffic reflective signs, reflective police uniforms, industrial safety signs, etc.

2. PET transfer film: It is mainly used as a carrier for vacuum aluminum plating, which is to place the PET film in a vacuum aluminum plating machine for aluminum plating, glue it onto paper, and then peel off the PET film. The aluminum molecular layer is transferred to the surface of the cardboard through adhesive action, forming the so-called aluminum plated cardboard. This is the purpose of this release film.

3. PET high gloss film: This release film is mainly used for high-end vacuum aluminum plating products. After aluminum plating, the film has a mirror surface and has good packaging and decoration effects; It can also be used for laser anti-counterfeiting base films, etc.

4. PET antistatic film: the antistatic film is characterized by adding a certain Antistatic agent to the PET film to form an extremely thin conductive layer on the film surface and form a continuous phase, improving the surface conductivity and making the generated charges leak as soon as possible.

5. PET heat sealing film: widely used in various fields such as packaging and card protection film for various commodities.

6. Chemical coating film: The release film is mainly used in the printing and aluminum plating industries.

7. PET heat shrinkable film: This release film is commonly used in the convenience food, beverage market, electronic appliances, metal products, especially in the main application field of shrink labels.

Summary: Understanding the characteristics, varieties, and application related knowledge of release film can save time and cost during use, reduce error rates, and truly improve work efficiency to a certain extent.
