Problems solved by technology

However, the existing technology focuses on a single point, and does not comprehensively consider paper environmental protection, water resistance, strength, and antibacterial properties. In addition, the produced wrapping paper does not have a very effective fresh-keeping effect.
[0005] At present, there is a lack of a wrapping paper made of non-wood pulp with good antibacterial and fresh-keeping effect and its preparation method

Abstract

The invention discloses a packaging paper prepared from a non-wood paper pulp and a preparation method thereof. The sizing agent of the packaging paper prepared from the non-wood paper pulp disclosed by the invention is prepared from straw pulp and bamboo pulp, wherein the ration of the packaging paper is 30g/m<2>-60g/m<2>; the content of the compound papermaking additive is 0.5%-1.0% of oven dry stock; the spraying or coating volume of the preservative preparation is 30-50mL/m<2>. The packaging paper disclosed by the invention has the advantages of strong waterproof property, high physical strength and good anti-bacterial preservation effect, capability of reducing sewage treatment cost and treatment difficulty and capability of reducing energy consumption and environmental pollution.

Description

technical field [0001] The invention relates to the technical field of paper manufacturing, in particular to a wrapping paper made from non-wood pulp and a preparation method thereof. Background technique [0002] In my country, paper is customarily divided into: ① cultural (printing, writing) paper; ② packaging paper; ③ household paper; ④ technical paper; ⑤ other (special) paper. The "paper" mentioned here includes paper and cardboard. In the production of the above-mentioned papers, according to the statistics of relevant departments in my country, cultural (printing) paper accounts for 25%, packaging paper accounts for 55%, household paper accounts for 8.4%, technical paper accounts for 7.5%, and other paper Accounted for 3.1%. [0003] As packaging materials, paper and cardboard have always occupied a dominant position, mainly because the application performance is manifested in many aspects, and the quality of its packaging performance depends on the packaging material...
