Abstract

The invention discloses an environment-friendly adhesive for paper package preparation, which is prepared from the following raw materials in parts by weight: 300 parts of water, 100 parts of corn starch, 3-5 parts of hydrogen peroxide, 2-3 parts of sodium hydroxide, 6-8 parts of starch reinforcing agent, 3-5 parts of sorbic acid, and 0.2 part of IPBC. The environment-friendly adhesive for paper package preparation has good adhesion fastness, high strength, mildew and corrosion property, safety and environment friendliness, and is especially suitable for adhesion of paper packages of foods, beverages, wine and other drinks and the like.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to an environment-friendly adhesive for manufacturing paper packaging. Background technique [0002] Paper packaging is widely used in the outer packaging of food, wine, medicine and health care products, etc., with a wide range of uses and a large amount of use. Adhesive is an essential material for packaging companies, and it is mainly used in the lamination process of face paper or cardboard. At present, starch glue is mainly used for the bonding of cardboard, but because this kind of adhesive has weak cohesive force, poor compression resistance, anti-mildew, anti-corrosion and moisture-proof ability, the quality of the produced products cannot be guaranteed. [0003] In the prior art, there are other components added to starch glue to improve its performance, such as adding formaldehyde to improve antiseptic ability, and adding borax to improve mildew resistance. However, su...
