I. Basic information

1, name: commonly known as silicone oil paper or release paper.

2. Structure: The release paper has three layers, the first layer is backing paper, the second layer is coating, and the third layer is silicone oil.

3. Role

(1), Gerasin (Gerasin is the backing paper) Silicone oil paper: it is resistant to high temperature, moisture and oil, and is generally used for food industry packaging.

(2) Ordinary release paper: moisture-proof and oil-proof, which can isolate products.

4. Applicable industries: electronics, automobile foam, printing, etc. Its application scope is mostly sticky, especially adhesive tape. Therefore, release paper will be used for products that generally use adhesive tape.

5. Classification

(1): By color:

A, single silicon white release paper, that is to say, one side is ordinary paper and the other side is silicone oil. It is commonly used.

B. Single silicon yellow (blue) release paper refers to release paper with yellow (blue) on both sides.

(2): Gram weight: from 35g to 250g (higher).

(3): According to whether silicone oil is added or not, it can be divided into silicone oil paper and coated paper.

Remarks: Coated paper means only backing paper and coated paper. If it is silicone oil paper, it means all three kinds of paper.

(4), according to single and double points.

A, double silicon single seal means that one side is silicone oil and the other side is only coated, which will improve the cleanliness.

B, bis-silicone means silicone oil on both sides.

C, monocrystalline silicon.

D coated paper, also known as white plastic paper.

(5): According to the origin of the products and materials.

A: Made in China.

B: Import.

Second, 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 different, most of them are not dust-free studios. Because of the cost, it is impossible to adopt a dust-free studio. Generally speaking, they are ordinary factories. A better one will have many improvements in environmental protection and environment, which will have an impact on cleanliness.

2. Release degree refers to the release degree of release paper. There is no absolute value at this point, depending on the formula of each manufacturer.

3, peeling force, peeling force refers to whether the product is easy to tear off, of course, there are strict test standards.

Third, the choice of release paper.

In the selection of release paper, the cost, product quality, production procedures, characteristics and uses of the prepared products are mainly considered.

1, product features: At present, the commonly used tapes in China are Sanzhi in Korea, Nitto in Japan and Sanmen in the United States. Because different tapes have different adhesive properties, this determines that we should consider this situation when choosing release paper.

2. Cost: There is a big difference between domestic and imported release paper. Generally speaking, domestic release paper is not very good. Especially, the three-meter adhesive tape and Nidong adhesive tape often have fog on the surface or low release degree, which can not tear the release paper and products well. It's just that domestic release paper is definitely cheaper than imported paper, and there is a big price comparison. If the company's products are exported, of course, it is best to use imported release paper, so that customs clearance will be smoother. Due to the characteristics of production equipment and production level of domestic release paper, the instability of domestic release paper in some products is determined, and the serious consequence will be the waste of adhesive tape.

3. Production process. The key point here is whether to punch or cut. Generally speaking, when punching or cutting, the thickness of release paper is required, because release paper with low gram weight is not easy to break when used for punching. Of course, this is also related to the fragility of the backing paper. The paper with poor brittleness will tear the paper and products when it is punched or cut. Can't achieve the ideal or expected effect.

4. usage. This is mainly reflected in the fact that some products only need to keep the balance of products during transportation, so it is required that the products are not easy to fall off when combined with release paper.

About the choice of release paper, it is mainly suitable. Personally, there is neither absolute good nor absolute bad. Domestic products have the advantages of domestic products, and imports also have the advantages of imports. The selection of release paper is equivalent to a process of college entrance examination, because all factors should be considered comprehensively, and the reasonable and cost-reducing effect can be achieved under the balance of all factors.
