Production process of concave surface packaging box

Abstract

The invention provides a production process of a concave surface packaging box, and relates to the technical field of product packaging and manufacturing. The roduction process comprises the following steps of S1, paperboard manufacturing, specifically, making papermaking raw materials into paper pulp, fishing out the paper pulp to form paper, processing and drying to form the paperboard; and S2, paperboard cutting, specifically, measuring and cutting the manufactured paperboard according to the designed packaging box size. A pressure head is used for heating and pressing at the adhesive dispensing position, so that a tile line starch adhesive coated on the adhesive surface of a packaging box can be gradually infiltrated, diffused and permeated into a paper fiber structure of the packaging box, and meanwhile, raw starch inside the adhesive can be quickly gelled and cured and evaporated to form moisture by virtue of the higher temperature of the pressure head, so that complete curing is achieved, in this way, the bonding position can be stabler and not prone to falling off, an internal product is protected more perfectly, the plastic is sealed through YH-T806 glue, the situation that the glue becomes yellow and hard due to long-time action, the packaging attractiveness of the product is affected can be prevented, and the method is more suitable.

Description

technical field [0001] The invention relates to the technical field of product packaging production, in particular to a production process of a concave packaging box. Background technique [0002] As the name suggests, the packaging box is a box used to package products. It can be classified according to the materials used in the box body, or according to the name of the product packaged inside. Its main function is to ensure the safety of the product during transportation and improve the grade of the product, etc. , with the increase of various products, the appearance of the packaging box has also changed, and each packaging box has its own characteristics. Material selection and structural improvement are achieved. At present, paper packaging boxes are widely used in product packaging. [0003] However, the traditional packaging box production method is not rigorous in the process of using glue. It is often just stuck with glue without further treatment of the stuck plac...

Problems solved by technology

[0003] However, the traditional packaging box production method is not rigorous in the process of using glue. It is often just stuck with glue without further treatment of the stuck place, so the glue is easy to fall off and cause damage to the internal product. At the same time, the outside Some of the glue used in plastic will harden and turn yellow, which will affect the overall appearance of the product
