With the development of market demand, the demand of PET film and PET release film in industrial production is increasing. There are more and more domestic companies producing PET films and PET release films, followed by a transparent market situation. I won't say much about PET film here, after all, it is not a special requirement for use. Domestic technology basically meets conventional purposes, and the quality difference is not significant. Here, let's talk about PET release film.

I believe many purchasing friends have asked many companies about the unit price, and the price of PET release film often varies greatly. Many friends here are very strange. In fact, this point needs to be analyzed from the perspective of the use of PET release films. The difference between ordinary isolation release films and optical grade release films is very large. Actually, they are basically industrial consumables and rarely end up in products. Common uses include the following:

1. The substrate for the label and tape industry.

2. Application of tape casting technology for polymer materials, such as microelectronic components.

3. Application in the optoelectronic die-cutting and punching industry.

4. Application of Lamination Technology in Various Multilayer Printed Circuit Board Industries

5. Production and application of covering film and pure adhesive film

6. PCB/PCL application

From the different processes, we can see that the quality requirements for PET release films vary in various situations. For example, the requirement for PET release films in ordinary die cutting and punching is uniform thickness and stable peeling force. The optoelectronic industry has added requirements for transparency and temperature resistance on the basis of stripping strength. Some polymer materials also need to consider the corrosion resistance of chemical reagents, the stability of silicone oil, and the non reaction with other chemical products while maintaining temperature resistance.

It is precisely because the process varies from industry to industry that the quality requirements for PET release films also vary. As long as ordinary PET films are used, the optoelectronic industry uses optical grade PET films as the substrate, and the coating process is much more precise than ordinary release film coating, with higher equipment requirements. As a result, the price of optical grade release films is much higher than that of ordinary release films. During the procurement process, all business friends must first understand their own manufacturing processes and order suitable products according to their requirements, rather than just demanding the best quality, which can lead to unnecessary waste.
