Many users do not have much understanding of PET release films, and they often encounter various problems when purchasing release films. Are release films and film products the same? Today, as a professional manufacturer of PET release films, we Ruichangxing will talk to you. When purchasing release films, users should note that there is a certain difference between this type of film and ordinary film products. Film products do not have any adhesive coating on them, so when touching the surface of the film with their hands, there will be no viscosity. Release films and film products have differences in production technology and feel. When we were making PET release films at Ruichangxing

At present, the processing and production industry attaches great importance to the selection of processing materials, as different types of materials can achieve different application effects during use. Materials with good texture and superior performance can achieve better application effects and improve work efficiency. Therefore, the use of PET release films is highly valued in processing sites, Below is a brief introduction by Ruichangxing, a release film manufacturer, on the advantages of this material. 1、 The use of PET release film can achieve higher stability. Although many materials can still achieve certain effects during use, most of them are lacking in stability

Recently, the editor saw many friends discussing how to solve the problems of oily and static discharge on the release surface of the release film online. Today, the release film manufacturer Ruichangxing will introduce the method to everyone. 1. After being attached to the tape, it cannot be peeled off, which is usually caused by uneven application. Some release films that are severely missed 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 simply poor in tightness,

1、 Preparation for startup of release film: 1. Scrub the machine's guide shaft and various auxiliary tools, clean the production site environment, drag the ground clean, and confirm the product specifications, required raw materials, and auxiliary supplies produced. 2. Confirm the required production process parameters for the release film, set the temperature, air frequency and other parameters according to the process parameters, turn on heating, inlet air for heating, and when the temperature reaches the set temperature, turn on the exhaust and recovery device. 3. Confirm whether the film path is correct, the adhesive surface of the raw material, and all rollers of the equipment are flexible and clean. 2、 Release film coating operation 1. Install the necessary raw materials for production, confirm the adhesive surface, make the film in the center of the machine, and inflate and fix the inflatable shaft

Release film is a commonly used material in heat transfer printing, which is made of PET substrate and coated with silicone oil, hence it is also called silicone oil film. So what are the main uses of it? What types can be divided into? Next, follow the editor of Ruichangxing to explore further! The conventional thickness of the release film generally 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. Now it has been widely used in packaging, printing, silk screen, pad printing, nameplate, film switch, flexible circuit, insulation products, circuit board, laser anti-counterfeiting, lamination, electronics, sealing materials, and reflective materials

Release film, also known as peel off film or isolation film, is a functional film that uses plastic film (sheet) as the substrate and is coated with release agent and adhesive on one or both sides of the film, making it non adhesive or slightly adhesive to specific materials under limited conditions of contact. Usually, in order to increase the release force of plastic films, plasma treatment, fluorine treatment, or silicone oil release agent are applied to the surface of the film material. Generally, the substrate of plastic films (sheets) includes materials such as PET, PE, PP, PC, and PS,; Make it suitable for various organic pressure sensitive adhesives (such as hot melt adhesives, acrylic adhesives, and rubber based pressure sensitive adhesives)

The key points for quality control of release film include coating uniformity, high residual adhesion, flatness, and high cleanliness. Ruichangxing generally controls the quality of release film from the following four points. 1、 High residual adhesion: In addition to being affected by the silicone oil formula, coating conditions, and substrate treatment conditions, the technical services of the silicone oil factory also need to be strengthened. 2、 Flatness: Coating equipment is crucial for smoothness, and the blending of silicone oil is also crucial. Most domestic coating factories do not have very good control over solvent based silicone oil. 3、 Coating uniformity: The release film should be evenly coated, in addition to selecting appropriate solvents and controlling the coating agent's

Below, the editor from the release film supplier will provide a detailed explanation of the basic material selection methods for PET release films! Different appearances require different stickiness. Depending on the appearance and pressure, the speed of viscosity increase varies. Generally, the protective film should be peeled off after a certain time to determine whether the viscosity is suitable. The use of rubber and acrylic protective films has different effects. Rubber is relatively soft, while acrylic is relatively hard. Generally, rubber type protective film is considered first, followed by acrylic type protective film. We recommend at least 80um of protective film for boards that need to be twisted or thick; The thicker the protective film, the higher the viscosity required

What is the relationship between release film and die-cutting? The following will be explained in detail by the release film manufacturer Ruichangxing. Die cutting is a cutting process used in the later processing of printed materials. The die cutting process can make release films or other paper printed materials into die cutting plates according to pre designed patterns for cutting, so that the shape of the release film is no longer limited to straight edges and right angles. Die cutting is a cutting process used in the later processing of printed materials. The die cutting process can make release films or other paper printed materials into die cutting plates according to pre designed patterns for cutting, so that the shape of the release film is no longer limited to straight edges and right angles. Traditional mode

According to different products and coating characteristics, the application method of release film also varies. At present, the coating methods of release film are roughly divided into: roller coating, mesh coating, scraper coating, and non-contact coating. Let's follow the editor of the release film manufacturer to see the characteristics of each of these release film coating methods. One of the coating methods for release film: scraper type coating: scraper type coating often results in uneven gluing, which is mainly related to the processing accuracy of the scraper, the installation method of the scraper, the angle of the scraper to the back rubber wheel during coating, and the viscosity of the coating. The precision requirement for the flatness of the scraper is high, which means that the scraper does not warp, deform or cut, otherwise it will be coated

Do you know the difference between fluorine release film and coating film? If you don't know, follow the editor of Ruichangxing Technology to learn more! 1、 Coating film: In order to improve the surface performance of PET film, improve printing adaptability, and enhance the adhesion of vacuum aluminum coating, corona treatment is usually used to increase the surface tension of the film. However, the corona method has issues with timeliness, especially in high temperature and humidity environments where the film tension after corona treatment is easily attenuated. However, the chemical coating method does not have such a problem, so it is favored by the printing and aluminum plating industries. Currently, a PET chemical coating system has been developed in China

Ruichangxing Technology Co., Ltd. is a company that relies on quality for survival. The company conscientiously produces high-quality adjustable release film, with positive quality and high-quality service, which is trustworthy. The following are common issues and precautions for fluorine release films organized by Ruichangxing Technology Co., Ltd.: Firstly, pay attention to distinguishing the front and back sides of single-sided fluorine release films. As single-sided fluorine release films only have one side for release and the other side is for PET substrate, if the release film is used on the wrong side, it will cause the film to stick to the surface of the board after pressing, making it difficult to tear it off. There are the following methods to distinguish the front and back sides: 1. Use adhesive paper to stick the release film surface. If it can be adhered, it is the PET substrate surface and the non stick surface
