Release film is also called silicone paper or anti stick paper, mainly used to isolate sticky objects. The release membrane mainly has the following characteristics:

1. The cleanliness of the release film actually refers to the cleanliness and cleanliness of the appearance. Because the working environment of release film manufacturers is different, it is almost rare to be in a dust-free working room. Generally, a better factory has significant advantages in environmental protection and environmental protection, as these can affect cleanliness. Many release film cleanliness is not contaminated during the production process, and the main reason is that during the slitting process, the cleanliness of the slitting manufacturer is not high, Dust is released only by electrostatic adsorption.

2. Moisture and temperature resistance of release film. The release film contains silicone oil, which has a certain degree of temperature resistance, but this mainly depends on the application of the product and the selection of domestic and imported silicone oil. Generally, the temperature of silicone oil can reach around 150 degrees.

3. Peeling force of release film: Peeling force refers to whether the product can be easily torn off, although there are strict testing procedures. Small slitting machines, currently mainly using national standards internationally, have a stripping force unit of grams. According to the different test results, it is generally divided into three procedures: light release, medium release, and heavy release. Light release refers to the ability to easily peel off the release film and tape protective film when they are attached, while medium release is not easy to peel off, while heavy release is difficult to peel off.

The above content is organized and shared by Reechas, a release film manufacturer, about several characteristics of release films.
