Background
Glassine paper is also called semi-transparent glassine paper, which is special paper with good internal strength and transparency prepared by coating and processing special base paper for glassine. The product has the functions of high temperature resistance, moisture resistance, oil resistance and the like, and is generally used as a release substrate of product labels, laser anti-counterfeiting labels, bar code information labels, double-sided tapes and special tapes in the industries of food, medicine, daily chemicals, logistics, supermarkets and the like. Driven by downstream industries such as logistics labels and electronic tapes, the demand of glassine paper as labels and tape backing paper is increasing dramatically. In order to meet the requirements of high-speed processing and high-speed automatic labeling, the glassine paper has the advantages of smooth surface, uniform thickness, higher tensile strength and transparency, uniform silicon coating, consistent release force, no breakage during labeling and correct identification of position information of the label by a photoelectric sensor. However, the currently produced glassine paper in China is inferior to imported products in the aspects of surface smoothness, oil resistance and the like, so that the release performance of the paper is poor, and high surface silicon coating amount is needed, so that the production cost is increased; the stripping effect after silicon coating is poor, and the required stripping force is large; in addition, the strength and the transparency are low, and the requirement of high-speed automatic labeling can not be met.
Surface sizing is the primary method of improving the oil resistance of glassine. However, the surface sizing agent used at present mainly comprises latex mixtures of starch, polyvinyl alcohol, acrylic resin and the like and a proper amount of oil-proof agent, and generally the oil-proof agent has large dosage and low oil-proof efficiency. And the opacity and the strength of the finished paper are lower, so that the application range of the glassine paper is influenced.
Natural cellulose is the most abundant biomass resource on earth, is the most widely distributed biopolymer in nature, and is present in various organisms such as plants, animals, and some bacteria. The Nano Cellulose Crystal (NCC) is nano cellulose extracted from natural fibers, is rigid rod-shaped cellulose with the diameter of 1-100 nm and the length of dozens to hundreds of nanometers, has the characteristics of nano particles, has certain unique strength and optical performance, and has wide application prospect.
