How is release paper made?

Release paper. This paper is usually used to protect, roll, and transport adhesive products such as tape to prevent them from adhering, wrinkling, and falling off during the process. Sometimes they are die-cut and formed. , striping and slicing can also be used for reposting, which is very convenient.

The general production process is to first select low-grade paper. Most of them use glassine paper. This kind of paper has good light transmittance and density, uniform texture, and stronger hardness than ordinary paper. Moreover, this low-grade paper is not afraid of damage. It has certain waterproof properties when it is wet, so it is most suitable to make low paper.

After selecting the low-profile paper, you can carry out dust removal. This is because the paper will produce powder when slitting, and the low-profile paper will need to be coated in the future. The coating must be carried out in a clean room, and powder is not allowed to exist. , followed by plastic surgery.

The purpose of shaping is also to release the bending stress of the roll paper when it is wound so that it can be as flat as possible during coating without any difference in thickness. Then it can be coated. The purpose of coating is to increase the separation of the paper. Form force is the reason why it is called release paper. It is called release paper only after it is coated, and the coating materials are also divided into light and heavy materials because this will produce a parameter of the paper, which is the release force. How do you understand size? To put it simply, the material you apply must not only allow the glue to stick up without falling off, but also prevent the glue from being peeled off, so this is very important. There are many types of glue, and the viscosity is high. They are low, so the release paper can only be made into a few specific grams as needed to cope with all the glues with different viscosities.

The coating materials are silicone oil. Between the silicone oil and the paper, because the two are not easy to combine, a layer of coating will be added first. It is equivalent to a middleman, sandwiched in the middle to bring together the buyers and sellers. Of course, this also has other functions, such as waterproofing and moisture-proofing. After it is completed, it is heated to solidify the silicone oil, and then it can be rolled up. The release paper is ready.
