The Classification of Release Film and Its Application
Advantages of PET release film
PET release film can be seen in various fields such as packaging printing, nameplate film, insulation products, reflective waterproofing, etc. Moreover, due to its excellent high-temperature resistance, it plays a significant role in die-cutting and adhesive products. This type of material, which is coated on one or both sides, has a smooth and even surface without wrinkles or bubbles, and is often used in heat transfer printing.
From the perspective of application, the advantages and disadvantages of PET release film are firstly in the printing field. Due to its good compatibility and low cost, it will be used for pattern printing processes. After being heated and pressurized by coating, the pattern can be transferred to porcelain, glass, plastic, and fabric, while maintaining accurate color matching and being more environmentally friendly. Secondly, heat transfer printing applications can be applied to mobile phones, 3c and other products, with clear quality and good light transmittance, and can also meet the production requirements of metal texture requirements.
In addition, PET release film can also be used in various types of products such as packaging decoration, reflective film, protective film, etc., and can be degraded to be more environmentally friendly. Some billboards and reflective signs with reflective requirements can also meet the requirements, and in some electronic display screens and mobile phone screen protection applications, it can play a high flatness, thermal stability, and solve various problems encountered.
1. Pay attention to the cost-effectiveness of the release film
Although each brand's PET release film may have certain differences in price, overall it is within a reasonable range. Therefore, to obtain a cost-effective PET release film, it is necessary to compare the products of several brands, including raw materials, processing technology, and quality, and select a high-performance release film.
2. Pay attention to the characteristics of the release film
Although the same substrate is used in the production of PET release films, the use of different release agents can result in different release film characteristics, with different fields and scopes of use. Therefore, when purchasing polyester release films, enterprises not only need to consider which material is good, but also the mechanical, chemical, and peel properties.
3. Pay attention to the scope of use of the release film
The main purpose of purchasing PET release film for enterprises is to meet the production needs of the product, so it is necessary to choose according to the scope of use of the release film to ensure that it can meet the production requirements of the enterprise's products. For example, single sided release film is suitable for sealing tapes, waterproof rolls, etc; If used for adhesive protection of reflective materials, it is suitable for double-sided release films.
