Release paper is commonly known as silicone oil paper, or anti-sticking paper.
1. Structure of release paper: The release paper has a three-layer structure, the first layer is bottom paper, the second layer is coated film, and the third layer is silicone oil.
Second, the role of release paper:
(1), Grassin (the bottom paper is Grassin) silicone oil paper: high temperature resistance, moisture resistance, oil resistance, generally used in food industry packaging.
(2), ordinary release paper: moisture-proof, oil-proof, play the role of product isolation.
3. Applicable industries of release paper:
For electronics, automobile foam, printing, etc., most of its application range is particularly sticky, especially tape. Therefore, products that normally require tape will use release paper.
4. Classification of release paper
1. By color:
a, Mono-silicon white release paper, refers to plain paper on one side and silicone oil on the other side. More commonly used.
b ,, single silicon yellow (blue) release paper, refers to release paper with yellow (blue) on both sides.
2. Divided by gram weight: from 35g to 250g (may be higher).
3. According to the presence or absence of silicone oil, it can be divided into silicone oil paper and coated paper.
Remarks: The coated paper is only the base paper and the coated film. If it is silicone oil paper, it means that there are three kinds of paper.
4. Divided by single and double sides:
a, Double silicon single seal, which means that one side is silicone oil, and the other side is only coated, which will improve the cleanliness.
b, double silicon, refers to silicone oil on both sides.
c, single silicon.
d, coated paper, also known as white plastic paper.
5. According to the production location of product materials:
a: Domestically produced.
b: Import.
Several characteristics of release paper:
1. Cleanliness. Refers to the cleanliness and cleanliness of the surface. Because the production environment of release paper manufacturers is not the same, most of them are not dust-free studios. Due to cost issues, it is impossible to use dust-free studios. Generally speaking, it is an ordinary factory building.A better one will have many improvements in environmental protection and environment, which will affect the cleanliness.
2.The degree of release refers to the degree of release of the release paper.There is no absolute value at this point.It depends on the formula of each manufacturer.
3.Peeling force, peeling force refers to whether it is easy when the product is torn off, of course, there are strict test standards.
Selection of release paper.
In the selection of release paper, the main consideration is cost, product quality, production procedures, the characteristics of the prepared products, and usage.
1. The characteristics of the products prepared: the most commonly used tapes in China are Sanzhi in South Korea, Nitto in Japan, Sanm in the United States, etc. Because different tapes have different glue characteristics. This determines when we choose release paper Consider the situation in this regard.
2. Cost: There is a big difference between domestic and imported release paper. Generally speaking, the taste of domestic release paper is not very good. Especially reflected in the preparation of three meters of tape and Nitto's tape, it often appears The surface is foggy or the degree of release is too low, it is not possible to tear the release paper and the product very well. Only the domestic release paper is definitely cheaper than imported. And there is a relatively large price ratio. If you consider that the company's products are used for export, of course, it is best to recommend the use of imported release paper, which will be smoother in customs clearance. Due to the characteristics of the production equipment and production level of domestic release paper, the domestic release paper is determined in The instability of some products, a serious consequence is the waste of tape.
3. Production process: The focus here is whether to stamp or cut. Generally, when stamping or cutting is involved, the thickness of the release paper is required, because the low-gram release paper is not easy to break when used for stamping. Of course , This is also related to the fragility of the bottom paper. The bottom paper with poor fragility will tear the paper and the product when stamping or cutting. The ideal or desired effect cannot be achieved.
4. Usage: This is mainly reflected in the fact that some products only need to maintain the balance of the product during transportation, then it will require that the product and the release paper are not easy to fall when combined.
The choice of release paper is mainly suitable for personal understanding. There is no absolute good or absolute bad. Domestic production has domestic advantages and imports have import strengths. The choice of release paper is equivalent to a college entrance examination process, because all factors must be considered comprehensively. In a balanced situation of various factors A reasonable and cost-effective effect can be achieved.
