Let's first understand that the items to be tested for release film include: color, appearance, curl, thickness, dry solids, surface resistance, peeling force, residual adhesion, and aging test, totaling 9 items. Color, appearance, curliness, and thickness can be easily measured with a simple naked eye and caliper, while dry solid content, surface resistance, and aging test are mainly electrical characteristics that are not required for general industrial applications, so they can be neglected. So, for the testing of release membranes, Z will mainly focus on measuring the release force! So how should the release force of the release membrane be tested? There is a lot of information about this online

What are the issues and effects of using some defective adhesive on PET release film? Some people feel sticky with the adhesive tape, but the sealing effect is not good enough. They always think they just opened it, and any chosen golden finger adhesive tape has the same quality of life? This is the problem with the glue. It feels very sticky to the touch, and the initial adhesion is good. After the glue jumps away, the adhesion is not good enough to grip. Double-sided tape die cutting professional Double-sided tape adhesive technology can not only solve all bonding problems, but also has a wide range of applications: whether in metal bonding, powder spraying surface, glass, plastic or fiber and other materials, Double-sided tape can

PET release film is made by coating a thin and uniform release agent on the surface of the PET substrate. PET release film has excellent high-temperature resistance function. Its physical characteristics are: smooth appearance, no particles, no bubbles, no wrinkles, etc. It is very suitable for processing various materials. Next, some of the main uses of PET release film materials were introduced. 1. Many links in the professional mobile phone production industry chain cannot be separated from PET release film materials, such as OCA optical adhesives used for screen structures. 2. Die-cutting profession 3, adhesive product profession 4, printed circuit board profession 5, packaging profession 6, silk screen profession 7, film switch production 8

For a product, we not only need to know its usage method, but also the storage method, so that it can be directly stored when not in use. If the incorrect method is used, it will affect the quality of the product, and the release film is the same. So what are the usage and storage methods of the release film? 1、 Storage 1. Store in a ventilated space or a cool place, and the temperature range should be kept between 5 ℃ and 32.5 ℃ 2. Keep away from ignition sources and compatible materials: strong alkali, Mineral acid, ammonia, chloride, strong oxidant. 3. Keep the container tightly closed when not in use. four

There is a word difference between release film and release paper, but there are significant differences. Release film is used to coat organic silicon release agents on the surface of environmentally friendly PET, PE, and OPP films, thereby exhibiting extremely light and stable release force on various organic pressure sensitive adhesives. Different organic pressure-sensitive adhesives, such as Hot-melt adhesive, acrylic adhesive and rubber system pressure-sensitive adhesive, require different release force of release film. Products with different viscosities need to be isolated. Adjust the force accordingly to obtain a very light and stable release force during stripping. The classification of release films can be divided into different substrates: PE release film, PET release film, OPP release film, and composite release film（

The function of release film is achieved by using different coating liquids, such as polyester type, polyurethane type, acrylic acid, silicon solution, etc. The purpose of coating the release film is to enhance its specific appearance function, such as enhancing film printing function, enhancing the aluminum layer peeling force after aluminum plating, and improving the smoothness of the film surface. When using different coating fluids for coating, it is necessary to adjust the corresponding production process accordingly to meet the technical requirements such as the curing time and temperature of the coating fluid, in order to ensure the stability of the coating production. Regarding equipment coating fluid: The coating fluid produced is generally water-based

High temperature resistance of PET release film: 1. Around 180 ° 2. It has excellent physical and chemical properties, dimensional stability, transparency, and recyclability, and can be widely used in fields such as magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging and decoration. 3. PET film is a packaging film with comprehensive performance. It has good transparency and luster; Has good airtightness and fragrance retention; Moderate moisture resistance, with a decrease in moisture permeability at low temperatures. The mechanical properties of PET film are excellent, and its strength and toughness are the best among all thermoplastic plastics. The tensile strength and impact strength are much higher than ordinary films; And quite

Fluorine release film, also known as 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. Property 1: It has good UV aging resistance, chemical corrosion resistance, and solvent penetration resistance. 2. The colors are generally transparent and milky white. 3. There is no migration phenomenon, eliminating the danger of the silicone release film transferring to the material it adheres to. 4. Controllable release force, high glossiness, high cleanliness, and residual adhesion

1. Pay attention to distinguishing between the front and back sides of the single sided release film. As the 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 board surface after pressing, making it difficult to tear it off. There are the following methods to distinguish the front and back: ① Use adhesive paper to stick the fluorine release film surface. If it can be adhered, it is the PET substrate surface, and the non adhered surface is the release surface; ② Mark the front and back of the film to distinguish between the front and back. 2. The surface static electricity of the release film can easily adhere to dust particles and affect the quality of the board surface if the static electricity of the release film is too high; Similarly, in order to reduce the static electricity of the release film, release

Analysis of Common Problems with PET Release Film Regarding the Use of PET Release Film in Die Cutting, the following problems are often encountered: 1. After the adhesive tape is attached to the release film, some of the adhesive tape peels back and makes a popping sound. 2. Anti stripping, the stripped material has not been stripped. 3. After punching and placing for a period of time, the tape and release film cannot be peeled off. 4. The surface of the release film is very oily, and it feels like the release layer is easily detached. 5. During the unwinding and winding process, the release film generates static electricity and absorbs

Release film refers to a thin film with distinguishable surface, which does not have viscosity or slight viscosity when in contact with a specific material under limited conditions. Release film is a silicone release agent applied to the surface of environmentally friendly materials such as PET, PE, and OPP films, allowing it to exhibit extremely light and stable release force against various organic pressure sensitive adhesives. Different organic pressure sensitive adhesives, such as hot melt adhesives, acrylic adhesives, and pressure sensitive adhesives for rubber systems, require different release forces. Depending on the viscosity of the isolation product adhesive, the release force should be adjusted accordingly to achieve an extremely light and stable release force during peeling.
