Due to the widespread use of release films in electronic products, there are extremely high requirements for their quality. Therefore, production enterprises of various products should pay special attention to quality issues when purchasing release films.

1. Pay attention to transparency
The professional release film is also called semi transparent Cellophane, which is transliterated from "glass". So transparency is a point that everyone should pay more attention to when choosing products, because only with good transparency can we meet the needs of automatic photosensitive labeling production lines, and the appearance of the products after production is also relatively beautiful and generous.
2. Pay attention to tightness
If the tightness of the release film is high, it can reduce the elasticity and oil resistance of the film during coating processing. However, if the tightness of the release film is too high, it will reduce the thickness of the film, and correspondingly, the stiffness of the film will also decrease. So when purchasing release film, enterprises should pay attention to the tightness of the film to ensure good oil resistance and thickness.
3. Pay attention to glossiness
One characteristic of the release film is its smoothness and luster, and the glossiness also affects the quality of printing. High glossiness can have a higher printing density based on the same printing ink film thickness, so the appearance effect of the release film with high glossiness will be better. Therefore, enterprises should pay attention to the glossiness of paper products when purchasing to ensure better printing results.
When purchasing release films, production enterprises should first pay attention to understanding the current market situation of this paper product and which type of release film is the best. After finding a suitable manufacturer, the quality of the release film should be judged by paying attention to the transparency, tightness, and glossiness of the film, in order to ensure the selection of the most high-quality and durable release film.
