No matter what product it is, people want to use it with good quality. PET release film is a commonly used material in industries such as adhesive, electronics, die-cutting, printing, etc; China has a large market demand every year, so do you know what factors affect the quality of PET release films? Let's take a look together today!

1、 Substrate: PET release film is the coating of silicone release agent on the surface of PET film, and the quality of the substrate directly affects its performance. Domestic PET film substrates lag behind foreign countries in terms of thickness control and thermal shrinkage.

2、 Residual adhesion rate: Residual adhesion rate refers to the force exerted on the release paper after the first peeling and the second peeling. The calculated data mainly reflects the curing effect of silicone oil.

3、 Peeling force: The magnitude of peeling force directly affects the performance of PET release film, and the general industry standard peeling force tolerance range is ± 15%.

4、 Processing environment: With the increasing progress of various products and the improvement of quality technology, the cleanliness requirements for PET release films are becoming increasingly strict, especially in the electronic film cutting industry.

Of course, there are many factors that affect the quality of PET release films in actual production, and different industries, companies, and processes have different requirements for the use of various types of films.
