The release film plays an important role in the production of double-sided tape. If die-cutting double-sided tape needs to use release film, the key features of release film are coating uniformity, high residue, flatness and high cleanliness; The following is a brief introduction of the manufacturer of Ruichangxing release film. Super calendered density paper (Glasin paper) has high density, smooth and bright surface due to the special calendering treatment of this paper, which not only maintains the advantages of good heat resistance of the paper, but also improves the water resistance, which is not easy to cause dimensional changes after moisture. It is an ideal anti stick paper substrate. The disadvantage is that the price is high. Polyester, polypropylene, or polyethylene film composite paper is used on various types of paper using seed paper (PET)

Let's take a look with the release film manufacturer Ruichangxing. Although there is a word difference between PET release film and PE release film, their functions and uses are not the same. What is the difference between PET release film and PE release film? Take a look. Before distinguishing between PET release membranes and PE release membranes, it is necessary to first understand their respective characteristics and applications. PET release film, also known as high-temperature resistant polyester film. 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. Capable of producing mobile phone LCD separators

Everyone's understanding of release film may only stay at the level of a layer of plastic film. With the rapid development of the packaging industry, release film has become an essential part of intelligent product packaging, especially with the emergence of functional release film materials, such as AR anti reflective film, AG frosted anti reflective film, mobile phone mirror film, anti peeping film, high-definition anti scratch film, etc, It is highly favored by people, so what are the basic functions of release membranes? The editor of Ruichangxing release film manufacturer will introduce one by one. 1. AG frosted release film adopts a three-layer structure, with a surface layer of

According to the editor of the Ruichangxing release film manufacturer, if the colored or transparent PET release film is not firmly adhered to the protected product, it will fall off during transportation and use. The biggest possibility is that the sensitive adhesive used in the production of the release film product is not sticky enough, and there is also a possibility that the pressure of the molding machine used by the user during the molding process is not enough, or the surface of the profile is not clean, There is dust or paint that affects the adhesion effect of the sensitive adhesive! The viscosity unit of PET release film is g/25mm, which refers to the tensile force required to open a 25mm wide spline, and the root of the release film

The common problems and solutions in the application of release film are what everyone needs to pay attention to. Below, the editor of Ruichangxing release film manufacturer will provide a detailed explanation for everyone. 1. Why does the release film material tend to curl up on both sides after a period of use? The release film performs well in the middle after a period of use, but the wings at both ends rise. The main reason for this phenomenon is that the release film has a high degree of stretching during the bonding process with the protected product. After being applied, unnecessary retraction occurs in high temperature environments, which often occurs in products of southern customers, Therefore, during the production process, attention should be paid to the impact of environmental temperature differences on the product

PET release film is a commonly used material for heat transfer printing, and the substrate is PET. After being coated with silicone oil, it is also known as silicone oil film. The traditional thickness ranges from 25um to 150um. Cold and hot tearing and matte surface, after anti-static and scratch resistant treatment, the product has good adsorption and adhesion. The following is a brief introduction from the manufacturer of Ruichangxing film release film to share with you the characteristics of high-quality PET release film. 1、 If the film thickness of PET release film is uneven, the printing depth will vary due to uneven force on the film surface, greatly affecting the quality of the final product. But high-quality PET release film thickness

The PET release film produced by the Ruichangxing film release film manufacturer is a very representative protective film product. Before use, it is necessary to roll the sample and observe the finished product under constant temperature for 48 to 72 hours. If there is no residual adhesive and it is easy to peel off, then this PET release film can be used. PET release film, like other protective films, also has a wide range of applications, including its application in dust-free workshops. Of course, there are also prerequisites, such as ensuring the cleanliness of the surrounding working environment when cutting and slitting PET release films; In the packaging and transportation process,

When it comes to PET release film, many people know that protective film is a thin film on mobile phone screens. However, in industry, especially PET release film, there are many uses. Below, we will explain to you. Where can PET release film be used in addition to the screen. PET release film includes: ① an isolation film containing adhesive resin material to prevent resin from sticking to the container. ② Soft molds used in the molding process of polymer materials. ③ Protective film for multi-layer circuit board manufacturing. ④ Plastic die-cutting process. ⑤ Protective film to prevent mutual adhesion of rubber products. ⑥ High strength pressure sensitive adhesive transfer substrate. ⑦ It plays a protective and isolating role in the mold of plastic products,

According to the editor of release film manufacturer Ruichangxing Film, frosted PET film is a high-quality single sided sand sheet.
