Abstract

The invention relates to field of paper making technology, and provides a making method for glassine paper. The tension between surface molecules of the glassine paper is high, and the glassine paper is good in oil resistance. The method includes the following steps: 1, body paper making; 2, coating and wetting, wherein a wetting machine is adopted for moisture adjustment, a heating device is installed in a wetting machine system, hot water is adopted for wetting, the temperature of the hot water is controlled within 30 DEG C-90 DEG C, the moisture content of the paper is controlled, and wetting is stopped when the moisture content of the paper reaches 20%-21%; 3, storage; 4, excessive calendaring, wherein a calender is adopted for calendaring, at least three calendaring areas are arranged on the calender, the pressure is 1000 KN/m<2>-1200 KN/m<2>, and the temperature is 180 DEG C-220 DEG C; 5, storage heat dissipation; 6, rewinding; 7, packaging and warehousing.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for preparing glassine paper. Background technique [0002] Glassine paper, also known as translucent paper cellophane, is a paper with good internal strength and transparency made of special base paper for Glassine after coating. It has the functions of high temperature resistance, moisture resistance and oil resistance, and is generally used for packaging in food, medicine and other industries, high-speed automatic labeling (especially suitable for high-speed label pasting), special tapes, double-sided tape substrate trademarks, laser anti-counterfeiting labels and other off-the-shelf labels. type applications, etc. The main use in medical products is as a release paper for tapes and dressing products. [0003] Developed countries have generally used glassine paper in industries such as medicine, food packaging and automatic labeling, and formed a series of produ...
