Classification and feature of release paper

Classification and feature of release paper

Classification and application of main products (by substrate)

- HDPE (Low pressure polyethylene) release liner: Used for sealing tape and other waterproof rolling material

- LDPE (High pressure polyethylene) release film: mechanical product packaging, hot melt adhesive packaging, health care products (diapers), anti-corrosion coil, etc.

- BOPP (stretch polypropylene) release paper: used for sealing tape, silent tape, etc.

- PET (stretch polyester) release liner: gum (back adhesive) protection, etc.

- Double-sided release paper.

-- Red/green polyolefin (PE) double side release liner: used for foam tape.

--Transparent PET double - sided release liner: double - sided adhesive.

-Anti-sun isolation film (HDPE silver coating film) : waterproof roll sunscreen cooling.

-Enhanced aluminum plating substrate BOPP enhanced (BOPET) : improve the adhesion of aluminum plating layer, can withstand 100℃ high temperature.

Classification by coating: it can be divided into ordinary silicone release paper and fluorine plastic release liner.

- High temperature release liner: polyimide film as the base material, coated with imported high temperature resistant silicone pressure sensitive adhesive, and then coated with polyester release liner. The tape has excellent high temperature resistance, electrical insulation and chemical resistance. And non-toxic, no odor, harmless to the human body and the environment, due to a very low release force.

Release paper basic information
Note: Give an overview of the industrial use of release paper, especially the use of release paper in die-cutting industry. Rather than release paper used in other industries.

 
Release paper related information

一. Basic information

1. Name: commonly known as silicone paper, or anti - stick paper.

2. Structure: ordinary release paper has three layers of structure, the first layer of paper, the second layer is the film, the third layer is silicone oil.

二. Classification

1. According to the color. Can be divided into blue, white and yellow. These are the three most common ones on the market.

2. According to gram. It can be divided into 65 grams of glassine, 85 grams of glassine, 85 grams of yellow paper, 100 grams of white silicon paper, 105 grams of double-sided silicone paper, 120 grams of single and double side silicone paper, 140 grams of yellow paper, 160 grams of yellow paper and so on. Basically from 25 grams to 250 grams.

3. According to the product material production place
 
(1). General domestic manufacturers in China will use domestic base paper, with silicon coating machine production, this is commonly known as domestic paper. And some domestic manufacturers will import some base paper from abroad, and then coated with silicon, which is also imported paper. Only many manufacturers on the market where the use of pure imported paper is a large part of the 3M material release paper. Perhaps it is the pure import paper that transfers hands to enter the country again after a few times use in a few foreign manufacturers.

(2). In terms of silicone oil, some domestic manufacturers in China use imported silicone oil. Some use domestic silicone oil. All these will affect the use and quality of products.

三．Scope and applicable industry

1. Most of them are attached to something sticky, especially tape or protective film. Therefore, the general use of tape products will be used release paper.

2. Broadly speaking, release paper is suitable for many industries, including food packaging, such as oil paper for KFC hamburgers, some ordinary food packaging bags, as well as the electronics industry, advertising materials industry, adhesive industry, die-cutting processing industry, etc.

四. Several characteristics of release paper.

1. Cleanliness: refers to the cleanliness and cleanliness of the surface, because the production environment of the release paper mill is not the same, it is basically impossible to produce in the dust-free studio, generally speaking, it is an ordinary factory, a little better will have a lot of improvements in environmental protection and environment, which will have an impact on the cleanliness. Most of the time, the cleanliness of the release paper is not polluted in the production process. Most of the reason is that when cutting, because the cleanliness of the cutting manufacturer is not high, electrostatic adsorption is caused by dust.

2. Stripping force: stripping force refers to when the product is torn off, whether it is easy, of course, this has strict test standards, now the main domestic use of national standard in China as the main. The unit of stripping force is grams, according to the test results are different, generally divided into three standards, light, medium, heavy release type. Light release refers to when the release paper and adhesive tape or protective film is relatively easy to peel, and the middle release is general peel, heavy release is difficult to peel.

3. Moisture-proof, temperature resistant, etc. Silicone oil has a certain temperature resistance, but this depends on the use of the product, and depends on the use of domestic and imported silicone oil. It can normally endure to about 150 degrees.
