PET release film plays an important role in the production of double-sided tape. If die-cutting double-sided tape requires release film, the key characteristics of release film are coating uniformity, high residual adhesion, flatness and high cleanliness, then what precautions should be taken when using transparent pet release film:

1. High residual adhesion: In addition to being affected by the silicone oil formula, coating conditions, and substrate treatment conditions, the technical services of the silicone oil factory also need to be strengthened.

2. Coating uniformity: The release film needs to be evenly coated. In addition to selecting appropriate solvents, controlling the concentration, viscosity, and solvent evaporation time of the coating agent, the coating equipment is crucial. Most domestic coating factories do not have very good control over solvent based silicone oil. Usually, there is a rainbow phenomenon, and in addition to strengthening the technical and analytical capabilities of coating, the technical services of silicone oil factories also need to be strengthened.

3. Cleanliness: To improve the cleanliness of PET release film, there are several parts to control. Firstly, the cleanliness and dust removal device of the base film, followed by the setting of a dust-free workshop, and then the dust removal setting of the slitting equipment. Improving the cleanliness of the product can also reduce the occurrence of heavy peeling of the release film,

4. Flatness: Coating equipment is crucial for smoothness, and the blending of silicone oil is also crucial. Most domestic coating factories do not have very good control over solvent based silicone oil;
