PET release film is a common material in the heat transfer printing process, with a normal thickness of 25um to 150um. It has the distinction of cold, hot, and glossy matte surfaces. After anti-static and scratch resistant treatment, the product has good adsorption and adhesion performance.

PET release film plays an indispensable role in daily life and work, and is a kind of Household goods. In various fields such as packaging printing, insulation products, reflective waterproofing, etc., release films can be seen, and due to their excellent high-temperature resistance, they play an important role in die-cutting and adhesive products. This type of material with single or double sided coating treatment has a smooth surface, a flat and uniform surface without wrinkles and bubbles, and is often used in the heat transfer printing process.

Due to the advantages of light weight, high strength, good transparency and gas resistance, non-toxic, odorless, etc., PET material has achieved rapid development. Since the 1990s, the consumption and application of plastic packaging materials have sprung up like mushrooms after a rain, and then with the maturity of touch technology.

The following three factors can be considered when select PET release film:

1. Cost performance of release film

Although there may be some differences in the price of PET release films for each brand, they are generally reasonable. Therefore, in order to obtain a cost-effective release film, it is necessary to compare the products of several brands in terms of raw materials, processing technology, quality, etc., and choose a release film with high cost-effectiveness.

2. Properties of release film

Although the same substrate is used in the production of PET release films, different release agents will result in different release film characteristics, and their application fields and scopes also have different focuses. So, when enterprises purchase polyester release films, they not only need to consider the quality of the materials, but also the mechanical properties, chemical properties, and peeling properties.

3. Scope of use of release film

The main purpose of purchasing PET release films for enterprises is to meet the production needs of products, so it is necessary to choose according to the scope of use of the release film to ensure that it can meet the production requirements of the enterprise. For example, single sided release film, suitable for sealing tapes, waterproof rolls, etc; If the reflective material uses reflective film, it is suitable for double-sided release film.
