How to use die-cutting materials first. 1. In the selection of die-cutting materials: generally, silicone tape is paired with fluorine release film, while acrylic tape is paired with silicone oil film. Of course, the materials selected for different products may also vary. 2. MY-2G is used for testing the release force of fluorine release film, and TESA7475 is used for testing the release force of silicone oil film (specific testing steps can refer to the standards provided by the manufacturer). Common problems and precautions are as follows: 1. Pay attention to distinguishing the front and back sides of a single-sided release film. As only one side of the single-sided release film releases, the other side is the PET substrate surface. If the release film is used on the wrong side, it will cause the film to stick to the surface of the board when pressing it down

PET silicone oil film, also known as PET release film, is a layer of silicone oil applied to the surface of PET film to reduce its adhesion and achieve release effect. The conventional thickness ranges from 25um to 150um. There are two types of products: cold and hot tearing and smooth and matte surface. After anti-static and scratch resistant treatment, the product has good adsorption and adhesion. It can be divided into single-sided release film and double-sided release film; According to the release force, it can be divided into light release membrane, medium release membrane, and heavy release membrane. Application scope: PET release film has been widely used in packaging, printing, circuit boards, laser anti-counterfeiting, lamination, electronics, and sealing materials

How to use die-cutting materials for fluorine release film first. 1. In terms of die-cutting material selection: generally, silicone tape is used with fluorine release film, while acrylic tape is used with silicone oil film. Of course, the materials selected for different products may also vary. 2. MY-2G is used for release force testing, and TESA7475 is used for silicone oil film. Common problems and precautions for release force testing should be distinguished between the front and back sides of a single sided release film. Due to the fact that a single sided fluorine release film only has one side for release and the other side is the PET substrate surface, if the release film is used on the wrong side, it will cause the film to stick to the surface of the plate after pressing, making it difficult to tear off. There are the following methods for distinguishing the front and back: 1

Fluorine release film, also known as fluorine film or fluorine film, is mainly used to isolate sticky objects, such as silicone tape, PI tape, etc. During production, storage, or transportation, fluorine release films play a role in protecting the adhesive from contamination and deterioration. Currently, the most widely used carriers are tape or adhesive products. Fluorine release membrane properties: 1. The color is generally transparent and milky white. 2. There is no migration phenomenon, eliminating the danger of silicone release membrane transferring to the material it adheres to. 3. Controllable release force, high glossiness, high cleanliness, residual adhesion of 94%, fluorine release film with good surface properties. 4

Fluorine release film, also known as fluorine film or fluorine film, is mainly used to isolate sticky objects, such as silicone tape, PI tape, etc. During production, storage, or transportation, fluorine release films play a role in protecting the adhesive from contamination and deterioration. Currently, the most widely used carriers are tape or adhesive products. Its application principle is the same as that of release film, mainly serving as an anti stick function. However, unlike silicone oil release film, fluorine exists in the form of fluoride in the release film, and most tapes are in the form of substrate and adhesive. There are many types of high-temperature resistant tape substrates with different temperatures of acrylic adhesive

Have you ever been troubled by purchasing release film? Don't worry, today the release film manufacturer Ruichangxing will tell you about the selection method of release films to help you solve your troubles. In fact, selecting release films is a very simple thing. Now, for the selection of protective films, you can verify it through the following methods: 1. If the smell is strong and there is a sour odor, the retention of this protective film is very poor, especially in low temperature environments, Basically, the sealing adhesive that sticks to the cardboard box will crack. The stronger the taste, the more sticky the initial adhesive feel, but soon the adhesive surface will become dry and lose its adhesive properties, which will be manifested in the protective film

Common problems and solutions for release film: 1. It cannot be peeled off after being attached to the tape, which is usually caused by uneven coating. Some release films with severe leakage can cause a certain part to have no release effect, resulting in the tape being unable to be peeled off. This problem should be avoided in circular knife die-cutting. 2. The oily release surface is mainly caused by the isolation agent system, and it is not necessarily bad for oily things. In fact, some oily release films are evenly coated on the surface and have better residual adhesion. But some are purely poor in sealing, and silicone oil is prone to detachment. These can also be determined through detection. 3. Static electricity issues, generally in addition to physical aspects

Recently, I have received many inquiries from friends to understand the quality issues with release membranes. We know that as a manufacturing industry, encountering quality problems is inevitable, and the most crucial thing is to understand the problem and solve it. We can better control the quality of the release film only after we know what quality issues may arise. What quality issues typically occur with release films? Below, Ruichangxing will share it with everyone. 1、 The scratch on the surface of the release film is a quality issue characterized by scratches on the flat surface of the film material, forming fine groove lines that can be observed through reflection. Scratches on the film surface can be divided into large-scale scratches and intermittent scratches

Fluorine release films require the selection of high-tech materials for product development, and low coating release films should be used for adhesive. The medium coating release film is more suitable for using oil glue and protective film, while the high coating release film is not suitable for using protective film. In terms of material performance, industrial materials must be adhered to so that they can be easily separated; Fluoride release membranes usually do not undergo chemical reactions with the resin system or contaminate the resin system; The elongation of the stretched release film is necessary. It can be consistent with the fibers to prevent deformation and distortion of the prepreg during the preparation process due to asynchronous stretching. Production Procedure: The key is whether to press or cut. During stamping and cutting, fluorine

We have previously mentioned that PET protective film is generally used for the protection of transportation products, lens and screen protection, material transfer, and waste disposal. What is the use of pet release film? In fact, people in the industry are well aware that it is generally used as a backing paper for adhesive products, automotive parts, electronic components, and die-cutting. Today, we will classify release membranes and explain their uses. 1、 What is the silicone oil release film used for? The release film commonly referred to in the industry is also known as silicone oil film. Silicon oil film applications can be divided into two categories: applications in the die-cutting industry and applications in the graphite industry. Silicon oil film applied in the graphite industry has uniform release force

PET release film is a common material in the heat transfer printing process, with a normal thickness of 25um to 150um. It has a cold, hot, and smooth matte surface, and has undergone anti-static and scratch resistant treatment. The product has good adsorption and adhesion performance. PET release film plays an indispensable role in daily life and work, and is a kind of Household goods. In various fields such as packaging printing, insulation products, reflective waterproofing, etc., release films can be seen, and due to their excellent high-temperature resistance characteristics, they play an important role in die-cutting and adhesive products. This type of material with single or double sided coating treatment has a smooth and clean surface, a flat and even surface without wrinkles and air
