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.

Described herein are coatings which impart oil, grease, and water resistance to various materials, such as paper, paperboard and polymeric materials. Such coatings may be applied as barrier coatings to the substrate materials in order to inhibit and prevent the transmission of oil, grease and water; that is, to prevent oil, water grease from passing into and/or through the substrate material. The coatings include an acrylic-based polymer latex, a styrene-butadiene rubber latex, a styrene-acrylic resin solution, a large particle size wax, and optionally, a small particle size wax. Also disclosed herein is a process of preparing the coatings. Also disclosed are products to which the coatings have been applied in order to impart oil, grease and/or water resistance, and processes for preparing such products.
