1, release film
1,1 Introduction
A release film refers to a film having a separation surface which is not sticky or slightly viscous after contact with a specific material under limited conditions.
Usually, in order to increase the release force of the plastic film, the plastic film is subjected to plasma treatment, or fluorine treatment, or a silicon release agent is applied on the surface of the film material, so that it exhibits for various pressure sensitive adhesives. Extremely light and stable release force. According to the different release force of the release film, the viscosity of the insulation product is different, and the release force is adjusted accordingly, so that it achieves extremely light and stable release force during peeling.

• 1.2 release film classification by substrate:

PET film--


PET film is a relatively comprehensive packaging film. It has good transparency and luster; it has good air tightness and aroma retention; it has moderate moisture resistance, and its moisture permeability decreases at low temperatures. PET film has excellent mechanical properties, its toughness is the best among all thermoplastics, tensile strength and impact strength are much higher than general film; and it has good strength and dimensional stability, suitable for secondary processing such as printing and paper bags. . The PET film also has excellent heat resistance, cold resistance, and good chemical resistance and oil resistance. However, it is not resistant to strong alkali; it is easy to carry static electricity, and there is no proper antistatic method. Therefore, attention should be paid when packaging powdery articles.

(1) PET high gloss film
In addition to the excellent physical and mechanical properties of ordinary polyester films, the film also has excellent optical properties such as good transparency, low haze and high gloss. It is mainly used for high-grade vacuum aluminum plating products. The film is mirror-coated after aluminum plating, which has good packaging decoration effect; it can also be used for laser laser anti-counterfeit base film. The high-bright BOPET film has a large market capacity, high added value and obvious economic benefits.
