Problems solved by technology

[0003] The purpose of the present invention is to overcome the disadvantages of glassine base paper in the prior art, such as insufficient strength, low transparency and high production cost, to provide a biologically treated light-coated glassine base paper and its preparation method. Larch, cheap and easy-to-obtain domestic eucalyptus wood, and glass wool fiber that can improve the strength of paper are used as raw materials. The transparency of glassine base paper is significantly improved through alkali treatment combined with biological enzyme treatment. The problem of lint and powder falling on the paper surface has excellent paper performance and high market value

Abstract

The invention discloses biologically treated light-coated glassine paper and a preparation method thereof. The method comprises the steps of material selection of selecting russia larix gmelini, fast-growing eucalyptus in the north sea and glass wool fiber as production materials; slurry preparation of larix gmelini, eucalyptus and wool fiber; and slurry preparation, biological treatment, papermaking and final paper forming operation. According to the preparation method of the biologically treated light-coated glassine paper, the transparency of the glassine paper is significantly improved by combining alkali treatment with bioenzyme treatment by selecting imported larix gmelini with excellent performance, cheap and available domestic eucalyptus and the glass wool fiber capable of improving the paper forming strength as the raw materials; meanwhile, the problems of linting and dusting of the surface of the glassine paper in the using process is solved through light coating; and the biologically treated light-coated glassine paper has excellent paper performance and relatively high market value.

Description

Technical field [0001] The invention relates to the technical field of papermaking, in particular to a biologically treated light-coated glassine base paper and a preparation method thereof. Background technique [0002] As a kind of industrial paper with uniform texture, glassine paper can be used to make bar codes, tapes, oil-proof packaging, etc. The glassine base paper in the prior art is mostly made directly from chemical wood pulp, so it is limited by the properties of natural fibers, the strength of the finished paper is insufficient, the transparency is low, and the paper surface is prone to lint and powder during use. Such circumstances make it difficult to meet the requirements of large-scale industrial use. At the same time, because all high-quality chemical wood pulp is used, its high price and high production cost. Based on this, the present invention selects imported larch with excellent performance, cheap and easily available domestic eucalyptus, and glass wool fi...
