In the selection of release coating, the main consideration is the cost, product quality, production process, characteristics of the prepared product, and usage.

1. Features of the prepared product: The most commonly used adhesive tapes in China are South Korea’s Sanzhi, Japan’s Nitto, and the United States’ SanM. Because different tapes have different glue characteristics. This determines that we should consider this aspect when choosing a release film.

2. Cost: There is a big difference between domestic and imported release film. Generally speaking, the domestic release film is not very good. Especially in the tapes of Preparation 3M and Nitto, the surface is often foggy or the release degree is too low, and the release film and the product cannot be well torn apart. But the domestic release film is definitely cheaper than the imported one. And there is a relatively large price ratio. If you consider that the company’s products are for export, of course, it is best to use imported release film, which will be smoother in customs clearance. Due to the characteristics of the production equipment and production level of domestic release film. It determines the instability of the domestic release film on some products, and the serious consequence is the waste of tape.

3. Production procedure: The key here is whether to stamp or cut. Generally, when stamping or cutting is involved, the thickness of the release film is required, because the release film with low weight is not easy to break when used for stamping. Of course This is also related to the fragility of the bottom film. A bottom film with poor fragility will tear the film and the product apart when punching or cutting. Can not achieve the desired or desired effect.

4. Usage: This is mainly reflected in the fact that some products only need to maintain the balance of the product during transportation, so it will require that the product and the release film are not easy to fall when combined.

Regarding the choice of release film, it is mainly suitable, in terms of personal understanding. There is no absolute good, and there is no absolute bad. Domestic production has the advantages of domestic production, and imports also have the strengths of imports. The choice of release film is equivalent to a process of college entrance examination, because all factors must be considered comprehensively. A reasonable and cost-reducing effect can be achieved when all factors are balanced.
