Due to the presence of paper fuzz and fibers on the surface of the coated paper, a certain amount of coating is necessary to ensure that there are no soaking points, silicone oil will not soak into the paper, and there will be no peeling defects. The coating amount of ordinary coated paper is 16 grams per square meter, and it is said that it once achieved 11-13 grams per square meter, which is quite close to the coating data of advanced foreign equipment. In theory, the printing manufacturer of coated paper can guarantee that the adhesive tape can be peeled off from the release paper, and any lower amount of coating is allowed.
In addition, some release papers are commonly used in many industries, and there are also those that do not use release agents. For example, label printing factories often apply a layer of varnish to the center where there is a need for release, which also has a certain release ability. Of course, the performance of the adhesive is weak. Otherwise, this kind of release ability is also in vain. There are also some release papers that use special adhesives and other formulas to consume, which have a small overall market share.
1. Cleanliness refers to the cleanliness and cleanliness of the appearance. Due to the different consumption environments of release paper manufacturers, most of them are not dust-free studios. Due to cost issues, it is not possible to use dust-free studios. Generally speaking, they are ordinary factories, and better ones will have many improvements in environmental protection and environmental aspects, which will have an impact on cleanliness
2. Release degree refers to the release level of release paper, and there is no absolute value at this point. It depends on the formula of each manufacturer to determine
3. Peeling force refers to whether it is easy for a product to peel off, although there are strict testing standards
