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

PET isolation membrane manufacturers guide you: Any process involving molecular level concentration and separation has the opportunity to apply membrane technology. The online purification of automotive electrophoretic paint uses ultrafiltration membrane to remove impurities and continuously ensure paint quality; Separation and concentration of intermediates using ultrafiltration membrane technology in the fuel industry. 1. The application of PET isolation membrane in environmental protection and water resource utilization Membrane technology has been widely applied in wastewater treatment, pollution prevention and comprehensive utilization of water resources. In many cases, release membrane wholesale not only treats wastewater, but also recycles useful substances and energy. 2. Treatment of various oily wastewater and waste oil using PET isolation membrane ① Oil recovery and reinjection

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.

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
