Characteristics and uses of PET release film

Single/double-sided PET release films are widely used in die-cutting and lamination of adhesive products due to their excellent high-temperature resistance. The product uses PET film as the base material and is evenly coated with a very thin layer of release agent on one or both sides. The surface of the PET release film is smooth and smooth, evenly coated, and free of wrinkles, particles, bubbles, and other defects. The product has excellent physical properties, small thickness tolerance, and low thermal shrinkage. It has high tensile strength, stretch resistance, and chemical inertness.

PET release films are generally used to isolate sticky materials and are widely used in electronics, inkjet printing supplies, reflective materials, tapes, self-adhesive waterproofing membranes, and other industries. Adhesive-type release films are divided into light peeling type, medium peeling type, and heavy peeling type based on the mobility of silicon and the change in peeling force after heating. The release force can be controlled according to requirements. The heat resistance is good.

Characteristics of release film when combined with adhesive products:

1.  There is no migration phenomenon. It eliminates the risk of the silicone release film transferring to the material it is tightly attached to.
2.  The tolerance of the weight per unit area of ​​single-sided or double-sided coating of PET release film is very small.
3. The base film has excellent mechanical strength and chemical properties.
4.  The high-temperature resistance can reach 180°C in a long time and 200°C in 10 minutes.
5.  High stability under extreme weather conditions.
6.  Extremely long shelf life.
