Preparation method of corrugated carton for containing tobaccos

Abstract

The invention relates to a preparation method of a corrugated carton for containing tobaccos. The preparation method comprises the following steps: 1, raw and auxiliary materials are prepared; 2, themixture enters a paperboard assembly line to be subjected to paperboard production, an adhesive and a purifying agent are added in the production process, the adhesive is composed of starch, water, caustic soda flakes, borax, a polyacrylic acid ammonium salt dispersing agent and urea resin, and the purifying agent is ellagic tannin phenol; 3, the produced paperboards are subjected to longitudinaland transverse cutting treatment; 4, printing is conducted, and meanwhile an anti-wear agent is added; and fifthly, grooving treatment is conducted, and then the corrugated carton can be formed through carton nailing and bonding. The corrugated carton prepared through the preparation method has good waterproof performance and high mechanical strength; meanwhile, the ellagic tannin phenol purifyingagent is added, so that the tobaccos can be effectively purified, the placed tobaccos can be purified earlier, the time required to be purified is shortened, and the production cost is reduced.

Description

technical field [0001] The invention relates to a method for preparing a corrugated box used for packing tobacco, which is used in the field of carton packaging preparation. Background technique [0002] Among all kinds of packaging for industrial products, corrugated boxes have become the mainstream of the packaging industry. Because of their light weight, foldability, low cost, environmental protection, easy specification changes, high-quality printing, and recycling, they can be used as renewable materials. Resources, therefore, are used more and more widely, but it has a fatal weakness: the surface of the carton is easily affected by moisture, and after being exposed to water, various physical performance indicators will drop sharply. It has certain moisture-proof and waterproof functions. [0003] In addition, the current corrugated cardboard boxes used to hold tobacco have low mechanical strength, are easily damaged, and are not conducive to secondary use. At the same...
