The "non-stick" miracle in multi-disciplinary applications characterized by release liners

In the modern manufacturing industry, release film, as a film material with special surface treatment, plays an important role in many fields because of its unique performance characteristics. From electronic power, medical, and automotive to construction, packaging, etc., the application of release film is ubiquitous and has become a key material in many production processes. In this paper, Dinli, the manufacturer of release film, will analyze the main features of release film, revealing its wide application and importance in industrial production.

     First, the basic concept of releasing film

     Release film, also known as stripping film, isolation film, separation film, etc., is a film surface with a special treatment, so that under limited conditions and specific materials in contact with the non-adhesive or only slightly sticky material. Common release films include PET, PE, OPP and other substrates, through the coating of silicone oil or release agent and other ways to achieve its unique release effect.

     Second, the main characteristics of the released film

     1. Excellent high-temperature resistance

     Release film performs well under extreme conditions, and its high-temperature resistance is especially outstanding. For a long period, the release film can withstand temperatures up to about 130°C, and for a short period, it can even reach about 180°C. This characteristic allows the release film to withstand temperatures up to about 130°C for a long period. This characteristic makes the release film widely used in industrial environments that require high-temperature treatment, such as automotive manufacturing, electronic component packaging and other fields.

     2. Excellent anti-adhesion

     The core characteristic of release film is its anti-adhesive properties. Through special surface treatment, release film can effectively prevent adhesives, resins and other sticky materials from bonding to its surface, thus protecting molds, production equipment and finished products during the production process. This characteristic makes the release film indispensable in the production of composite materials and the manufacture of electronic products.

     3. Stable release force

     The release force of the release film can be precisely adjusted by controlling the weight per unit area of the coating and the mobility of the silicon, thus realizing a variety of types of light, medium and heavy peeling. This stabilized release force not only contributes to production efficiency but also ensures the quality of the final product.

     4. Excellent chemical stability and mechanical strength

     Release film base film has excellent chemical stability and mechanical strength, and can resist a variety of chemical substances and mechanical stress. This characteristic enables the release film to maintain stable performance in harsh industrial environments.

     5. High cleanliness and flatness

     Release films are usually produced in class 10,000 clean rooms, which ensures the high cleanliness and flatness of the products. Its surface is smooth and clean, with no wrinkles, no scratches, no particles, no bubbles and other defects, providing a good foundation for subsequent processing and use.

     Third, the application areas of the release film

     1. Electronic power industry

     In the electronic power industry, the release film is widely used in cell phones, computers and other electronic equipment screen lamination process, effectively preventing glue and other adhesives directly from in contact with the surface of the equipment. At the same time, the release film can also be used as an insulating material to ensure the stable operation of electronic equipment.

     2. Medical Industry

     In the medical field, release film is used as a protective film on the seals of sanitary napkins and diapers, which is convenient for users to tear off. Its excellent anti-adhesion properties and cleanliness ensure the hygiene and safety of the products.

     3. Automotive industry

     In the automotive manufacturing process, release films are used to mold various sealing tapes and windshield repair films, and are also used in the pressing process of vehicle interior parts. The high-temperature resistance and anti-adhesion properties of release liners ensure the ideal surface texture of the components.

     4. Construction

     In the construction sector, release liners are used in the manufacture of precast concrete components and decorative panels to help cleanly release the finished product from the mold and protect it from damage.

     5. Packaging and Composites

     In the packaging and composites industry, release liners are often used as a backing film for self-adhesive labels and stickers, ensuring that the labels peel off easily and leave no adhesive residue. Also, in the production of composite materials, release liners are used to cover prepreg materials to prevent resin adhesion.

     Conclusion

     Release films play an important role in many fields with their unique performance characteristics. With the continuous progress of technology and the increase of market demand, the related technology of release film will be continuously innovated and improved. In the future, the release film will show its unique value and charm in more fields, bringing more convenient and efficient solutions for industrial production.
