Embodiment 1

[0012] A kind of packaging paper, use 50 parts by weight of coniferous pine wood pulp and 26 parts by weight of eucalyptus wood pulp to add water to make a raw slurry with a mass concentration of 4%; °SR, slurry a with a wet weight of 11g; add 4.1% by mass latex and 8.1% by mass wet strength agent to slurry a, then go through inclined wire forming, dehydration, large tank pre-drying, and two-cylinder drying After processes such as calendering, cylinder drying, coiling, rewinding and cutting, the base paper is obtained; finally, the front side of the base paper is coated with a glue amount of 12g / square meter, and the reverse side is coated with a glue amount of 2g / square meter. After drying, winding, rewinding and slitting, latex sandpaper base paper is obtained.

Embodiment 2

[0014] A kind of packaging paper, use 59 parts by weight of coniferous pine wood pulp and 30 parts by weight of eucalyptus wood pulp to add water to make a raw slurry with a mass concentration of 5%; °SR, slurry a with a wet weight of 12g; add 4.5% by mass latex and 8.9% by mass wet strength agent to slurry a, and then go through inclined wire forming, dehydration, large tank pre-drying, and two-cylinder drying After processes such as calendering, vat drying, coiling, rewinding and slitting, the base paper is obtained; finally, the front side of the base paper is coated with a glue amount of 18g / square meter, and the reverse side is coated with a glue amount of 6g / square meter, and then again After drying, winding, rewinding and slitting, latex sandpaper base paper is obtained.

Abstract

The invention provides packaging paper, aiming at solving the problems. The packaging paper comprises the following components in parts by weight: 50-59 parts of needle pine pulp and 26-30 parts of eucalyptus pulp; water is added into the raw materials to prepare 3%-6% raw pulp; the raw pulp is pulped to obtain 3.5%-5.5% slurry a with the with the beating degree of 23-32 degree SR and the wet weight of 9g-14g; latex with the mass percent of 4.1%-4.5% and a wet strength agent with the mass percent of 8.1%-8.9% are added into the slurry a to obtain a mixture; then the mixture is subjected to the procedures of forming an inclined net, dehydrating, pre-barking in a large cylinder, drying, calendering by a secondary cylinder, drying in an assembled cylinder, coiling, recoiling and cutting to obtain raw paper; and finally, the front surface of the raw paper is coated according to the glue amount of 12-18 grams per square meter and the back surface of the raw paper is coated according to the glue amount of 2-6 grams per square meter, and then the raw paper is dried, coiled, recoiled and cut to obtain latex abrasive paper raw paper. The packaging paper has the characteristics of good flexibility, uniform gloss finish of a paper surface, moisture prevention and the like.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a packaging paper. Background technique [0002] Packaging (packaging) is the overall name of containers, materials and auxiliary materials used according to certain technical methods to protect products during circulation, facilitate storage and transportation, and promote sales; it also refers to the use of containers, materials and auxiliary materials to achieve the above purposes. Operational activities such as imposing certain technical methods in the process of objects. Marketing packaging focuses on planning strategies and becomes packaging in a broad sense. It can also dress someone or something up or try to help him to be perfect in some way. [0003] According to the Chinese national standard GB / T4122.1-1996, the definition of packaging is: "to protect products during circulation, facilitate storage and transportation, and promote sales, the overall package of conta...
