[Release film] How should companies choose PET from the film!


PET release film application advantages

In the fields of all kinds of packaging printing, Ming plate films, insulating products, reflective waterproof, etc., they can see the figure of the PET release film. Because of its more excellent high temperature resistance, in the mold cut, the adhesive product is large, this single-sided or double-sided coating material surface is smooth, the flat and uniform surface is free, in the heat It is also often used in the transfer.


From the application to see the advantages and disadvantages of the PET release film, the first is the field of printing, because of its preferred compatibility and low cost, it will be used to perform pattern printing processes, and then heat and pressurize the glue, Turn the pattern to porcelain, glass, plastic, fabric, and maintain accurate set of colors, and more environmentally friendly. Secondly, the thermal transfer application can be applied to mobile phones, 3C and other products, and the quality and light transmittance are good to satisfy the production requirements of metal texture.


In addition, the PET release film can also be used in a variety of products such as packaging, reflective film, protective film, and can degrade more environmentally friendly, some of the reflective billboards, reflective markers, etc. can also be completed, and in part The electronic display, the protection application of the mobile phone screen, can play a high level intensity, thermal stability, etc., and solve all kinds of problems encountered.


In addition, the mold cuts will also be used in the PET release membrane, and there can be different lying force values. This can be detected by the instrument. Different release power is different for the peeling effort of the product, which is not small for its application. Influence, this is also different analytical applications such as production protection, bonding die cut classes, production rubber bands, fitting criticism, etc..


How companies should choose the correct PET film


1, pay attention to the cost performance of the release film
Although each brand's PET release film has a certain difference in the price, it is in a reasonable range, so I want to get a good-to-hunting PET release film, it is necessary to be a few The brand's goods are compared, compared to raw materials, processing technology, quality and other levels, select high cost-effective release films.


2, pay attention to the characteristics of the release film
Although the same substrate is used in the production of PET release films, different release membrane properties are obtained, and the fields and ranges are used in terms of use. Therefore, when purchasing polyester leaves, it is better to see which material is good, but also mechanical properties, chemical performance and peeling performance.


3, pay attention to the range of use of the release film
The main purpose of enterprises to purchase PET film production is to meet the demand for the product, and therefore need to be selected according to the scope of the release film, in order to ensure that it can meet the production requirements of enterprise products. For example, one surface of a release film suitable for tape closure, waterproofing membranes and the like; if the adhesive for protecting the reflective material is applied to a double-sided release film.
