1. The material identification process of the release paper manufacturer:
Sometimes, silicon-coated glassine release paper is difficult to distinguish from ordinary silicone-coated release paper with the same specification and color when placed on a desktop, and they also have the same release characteristics. However, the glassine paper is made of high-pressure light, so the paper is more uniform and flat, and generally more transparent, so you only need to look at the transparency and the uniformity of the paper by looking at the brightness of these two similar papers. If it doesn’t work, just tear it open with your hands. The only thing you can see is the PE-coated paper.
2. The difference between coated paper and release paper:
Glossy plain paper and release paper sometimes look very similar. For die-cutting, release paper is used, but if they are torn apart by hand, the ordinary paper has only fiber hairs at the edge of the tear, while the coated paper In addition to wood fiber, paper will also have some small membranes. If the tape is used for testing, the coated paper will make a noise during the process of removing the tape, but nothing will stick to the tape, while the glossy plain paper will stick to the coating and wood fiber on the surface of the paper.
3. Material identification process of coated paper:
From the appearance point of view, there is no difference between coated paper and plastic release paper coated with silicon in the same specification; and PE coated paper with silicon is not easy to distinguish from ordinary coated paper, but you only need to use With a few simple tools and operations, they can be distinguished well. A piece of tape, a signature pen, plus a small tear paper test, there are plastic release paper and coated paper of the same specification. It is also invisible in appearance, but the difference between the two can also be distinguished by the above method.
