Abstract

The invention relates to a bovine base solution packaging raw paper used in production of liquid packaging boxes. The base solution packaging raw paper comprises a surface layer, a core layer, a base layer and a coating layer and is characterized in that the surface layer comprises chemical hardwood pulp and softwood pulp; the core layer comprises mechanical pulp, chemical hardwood pulp and unbleached pulp; the base layer comprises unbleached pulp; and the coating layer comprises calcium carbonate, porcelain clay, adhesive, a water-retaining agent and a water repellent agent. The base solution packaging raw paper disclosed by the invention has the advantages of environment protection, low cost, high physical strength as well as good decoration property and printing performance of products, accordance with the food requirement and no harm to human bodies, wherein the using amount of chemicals is reduced so that the environment pollution is reduced, and the using amount of chemicals is reduced so that the cost is reduced.

Description

technical field [0001] The invention relates to a cow bottom liquid wrap base paper used in the production of liquid packaging boxes. Background technique [0002] At present, the known base paper for liquid packaging is produced with chemical-mechanical wood pulp and bleached chemical wood pulp, then coated with a film, and then printed and formed into a packaging box. Traditional liquid packaging base paper uses a large amount of bleached pulp, a large amount of chemicals, a large base paper basis weight, and high cost. [0003] Most of the existing liquid packaging base papers are produced with bleached chemical pulp, which has high product weight, high pressure on environmental protection, high cost and serious waste of resources. [0004] Therefore, it is necessary to design a new bag-shaped base paper to reduce the amount of chemicals used, thereby saving costs and reducing environmental pollution. Contents of the invention [0005] In order to solve the above prob...
