How To Choose Back Release Paper

The  back release paper is a release paper that prevents the prepreg from sticking and protects the prepreg from contamination. It is made of paper coated with anti sticking substances, and its model should be distinguished according to the difference in material, thickness, elongation, single and double sides. Nowadays, it is widely used in various fields of life. This article briefly introduces how to choose the right silicon coated paper.

1. Back release paper and product characteristics

Taking tape as an example, the more commonly used tapes in China are Sanzhi in South Korea, Nitto in Japan, and SanM in the United States. Because different adhesive tapes have different properties, this determines that we should consider this aspect when choosing release paper. Case.

2. Back release paper and product cost

There is a big difference between domestic and imported release paper. Generally speaking, the domestic reputation is not very good. For tapes, especially the tapes of SanM and Nitto, the surface is often foggy or released. The degree is too low to tear it apart from the product well. It’s just that domestic ones are definitely cheaper than imported ones, 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 ones, which will be smoother in customs clearance; due to the domestic production equipment and The characteristics of production level determine the instability of domestic release paper in some products, and the serious consequence is the waste of tape.

3. The production process of the back release paper

The focus here is whether to punch or cut. Generally, when punching or cutting is involved, the thickness of the release paper will be required, because it is not easy to be punched when it is used for punching with low gram weight. The shredding is related. The bottom paper with poor friability will tear the paper and the product apart when punching or cutting, which cannot achieve the ideal or desired effect.

4. The use of the back release paper

This is mainly reflected in the fact that some products just need to maintain the balance of the product during transportation, so it will require that the product and the release paper are not easily dropped when combined.

Regarding the choice of release paper, it is mainly suitable. In my personal understanding, there is no absolute good or absolute bad. Domestic production has the advantages of domestic production, and imports also have the strengths of imported ones. The selection of silicon-coated paper is equivalent to a process of college entrance examination, because all factors must be considered comprehensively, and a reasonable and cost reducing effect can be achieved under the condition of a balance of various factors.
