We would like to introduce two different types of films, release films and protective films. Industry newcomers may easily confuse these two types of protective films. What are their differences and what are their respective uses? 

Distinguish from materials

PET protective film is a type of adhesive that is applied to PET materials with different viscosities. It is divided into three types: high viscosity, medium viscosity, and low viscosity, and has adhesive protection effects. Its scope of use is to fit with release film or release paper, cut into different product shapes, tear off auxiliary materials, and transfer them to other products, such as mobile phones, computers, etc., to play a screen saver role.

PET release film is coated with release agent, which is divided into three types of release force: light, medium, and heavy. 4102 has an anti stick 1653 effect,PET release film is mainly used for laminating and cutting with protective film, various adhesive tapes, etc. PET release film is an auxiliary material that is mainly easy to tear.

Distinguish from product characteristics

Characteristics of PET protective film: PET protective film is a packaging film with comprehensive performance. It has good transparency and luster; It has good airtightness and fragrance retention, excellent mechanical properties, and good stiffness. It has stable size, heat resistance, cold resistance, chemical resistance, oil resistance, no residue, no residue, and good adhesion and stability

The characteristics of PET release film: the surface of the film is flat and smooth, evenly coated, and free from defects such as wrinkles, tears, particles, bubbles, and pinholes. The product has small thickness tolerance, low thermal shrinkage, and good flexibility.

Differentiate between different uses

PET Protective film: Its scope of use is to mold and cut into different product shapes after bonding with release film or release paper, tear off auxiliary materials, and then transfer them to other products, such as mobile phones, computers, PADLED monitors, digital cameras, etc., to play a screen saver role.

   There is no non adhesive or non adhesive release film. It can be used as a backing paper for adhesive products, automotive parts, electronic components, and die-cutting.
