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.

1. Pay attention to the cost-effectiveness of release membranes

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. Pay attention to the properties of the release membrane

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. Pay attention to the scope of use of release film

      The main purpose of the release film is to meet the production needs of the product, so it is necessary to choose according to the range 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.
