After the film is coated, the release agent is coated on the film surface to produce the release paper. Because there are paper wool and fiber on the surface of the paper, so the film must reach a certain amount to ensure that there is no penetration point, to ensure that silicone oil will not penetrate into the paper, in order to ensure that there is no bad peeling.

Generally, the amount of film-spraying paper is 16 grams per square meter. Theoretically, as long as the tape can be guaranteed to peel off the paper, the lower amount of film-spraying is permissible. The paper is divided into single shower and double shower. Generally, one-sided stripping paper is single-sprinkled, of course, there are double-sprinkled single-sided stripping paper, because the thickness of the stripping surface is generally 20 grams, the non-stripping surface is generally thin 15 grams, such stripping paper is more flat. If it is double-sided film coated with 22 grams of film, it is more suitable for double-sided release paper. Generally, all types of paper are selected from all kinds of wood pulp and paper, especially in the electronics industry.

If straw pulp paper is used, there will be a lot of paper scraps and easy to cut edges when die-cutting. Whole wood pulp paper is generally known as kraft paper, such as natural color kraft paper (commonly known as: the cow), white kraft paper (commonly known as: white cow), yellow kraft paper (commonly known as: Japanese yellow cattle), blue kraft paper (commonly known as: Indonesian blue cow). Of course, there are also all-wood pulp double-adhesive paper for the base paper, more with photographic paper for the base paper, as well as with copperplate and white paper, cow cards, milk cards and other paper for the base paper. As long as the film of paper and plastic fastness to meet the requirements, as long as the film does not penetrate the point, the film evenly flat, what should be said that the paper can be used as the base paper.
