Zusammenfassung: | Disclosed is a manufacturing process of intermittent coating release paper, which includes: a) undercoating; b) primary drying in a drying oven; c) printing optical marks; d) coating silicon in a section; e) accurately coating heat-sealing material on front and back sides of the base material; f) secondary drying, rolling up, the action of coating the silicon and coating the heat sealing material is precisely positioned by using the optical marks printed in the previous process. The manufactured release paper can be directly applied to the packaging of women's sanitary napkins, pads, and maternity napkins, there is no need to use spaced release paper, the whole can be degraded or recycled for pulping, and can also reduce the use of various coating materials during production, reduce production costs, thus being beneficial to improve the production level of the existing process and the ecological environment protection. |
