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

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
