After the original paper has been laminated, a release agent is applied to the laminated surface to produce the release papers. As the paper has paper hairs and fibres on the surface, the lamination must be applied to a certain amount to ensure that there are no penetration points, that the silicone oil does not penetrate the paper and that there are no peel-off defects. Theoretically, as long as the tape can be peeled from the release papers, any lower amount of lamination is acceptable. Film laminated release papers are divided into single and double laminated. Generally, single-sided release papers are single laminated, but there are also double laminated single-sided release papers, as the lamination on the release side is generally thicker at 20 grams and the non-release side is generally thinner at 15 grams, which makes the release papers flatter. If the laminate is 22 g on both sides, it is more suitable for double-sided release paper. The laminated release paper is generally made of full wood pulp paper, especially in the electronics industry. If straw pulp paper is used, there will be a lot of paper dust and easily broken edges when die-cutting. Full wood pulp paper is generally known as kraft paper, such as this colour kraft paper (commonly known as: this cattle), white kraft paper (commonly known as: white cattle), yellow kraft paper (commonly known as: Japan yellow coloured cattle), blue kraft paper (commonly known as: Indonesia blue coloured cattle). Of course, there is also a full wood pulp double glue paper as the original paper more with photographic paper as the original paper, as well as with coated paper and white board paper, kraft card, milk card and other paper as the original paper. As long as the fastness of the laminated paper can meet the requirements, as long as the laminated film does not have penetration points and the lamination is even and flat, it should be said that any paper can be used as the original paper.
