In the daily production process of Double-sided tape, release film plays an important role and effect. The editor of the release film manufacturer of Ruichangxing Company shares relevant content with everyone on the role of PET release film in production.

PET release film plays an important role in the production of double-sided tape. If die-cutting double-sided tape needs to use release film, the key features of release film are coating uniformity, high residual continuity, flatness and high cleanliness.

1. Cleanliness: There are several parts that need to be controlled to improve product cleanliness. One is the base film cleaning and dust removal device, the second is the setting of a dust-free workshop, and the second is the setting of dust removal for the slitting equipment. Improving product cleanliness can also reduce the re stripping of the separation film.

2. Flatness: The flatness of the coating equipment is crucial, and the deployment of silicone oil is also crucial. Most domestic paint factories do not have good control over solvent based silicone oil.

3. High residual continuity: In addition to the silicone oil formula, coating conditions, and substrate treatment conditions, the technical services of the silicone oil factory should also be strengthened.

4. Coating uniformity: In addition to selecting appropriate solvents to control the concentration, viscosity, and evaporation time of the coating, PET coating equipment is also crucial. Most domestic coating factories do not have good control over solvent based silicone oil. Usually, there is a rainbow phenomenon, and in addition to strengthening the technical and analytical capabilities of the coating itself, the technical services of the silicone oil factory also need to be strengthened.

Transparent PET release film is a packaging film with comprehensive performance. Good transparency, luster, air tightness, good fragrance retention, and moderate moisture resistance. At low temperatures, the moisture permeability decreases, and PET film has excellent mechanical properties. Its toughness is that the tensile strength and impact strength of all thermoplastic plastics are much higher than ordinary films; Good strength, stable size, suitable for secondary processing such as printing and paper bags. PET film also has excellent heat resistance, cold resistance, chemical resistance, and oil resistance. But it is not resistant to strong alkalis and is prone to static electricity, and there is no suitable anti-static method, so attention should be paid when packaging powder items.
