Production method of waterproof corrugated carton

Abstract

The invention relates to a production method of a waterproof corrugated carton. The method is characterized by comprising the following steps of S1, preparing a corrugated board; S2, carrying out waterproof treatment on a surface layer of the corrugated board; and S3, carrying out die cutting, mark pressing and carton nailing / carton gluing on the waterproof treated corrugated board prepared in theS2, and then the waterproof corrugated carton is obtained. The invention further discloses the waterproof corrugated carton produced according to the production method of the waterproof corrugated carton. The production method of the waterproof corrugated carton is simple and feasible in process, low in production cost, good in production efficiency, and high in finished product qualification rate; and the produced waterproof corrugated carton is remarkable in waterproof effect and large in mechanical strength.

Description

technical field [0001] The invention relates to the technical field of carton production, in particular to a production method of waterproof corrugated cartons. Background technique [0002] At present, corrugated cartons have become the main supplies in the packaging industry, whether in industrial products, daily necessities or agricultural products. High-quality printing can be used as a renewable resource after recycling, so it can be used more and more widely. [0003] Corrugated cardboard is die-cut, creasing, nailed or glued to make corrugated boxes. At present, the commonly used corrugated cartons on the market are face paper, corrugated paper and inner paper from outside to inside, and the corrugated paper has a "V"-shaped wave structure. The main component of corrugated cartons is paper fiber with strong water absorption, which is easy to be damp and impregnated with oil. When corrugated cartons are placed on the ground, if the ground accidentally accumulates wat...

AI Technical Summary

Problems solved by technology

The main component of corrugated cartons is paper fiber with strong water absorption, which is easy to be damp and impregnated with oil. When corrugated cartons are placed on the ground, if the ground accidentally accumulates water, the cartons will be damaged, which will easily cause a lot of cartons to be wasted. Seriously increased the user's cost of use

In addition, the method for producing corrugated cartons in the prior art is complicated in process and low in production efficiency. The corrugated cartons produced generally have high formaldehyde emission, are not easy to degrade, are not environmentally friendly, have complex structures, high costs, and poor thermal insulation effects. It is necessary to add an additional insulation layer, which takes up the packaging space and reduces the packaging capacity; the mechanical properties such as strength are poor, and it is easy to be damaged or torn. The knot effect is not good, the force is easy to fall off, the adhesive is easy to age, not waterproof, etc., the waterproof effect is poor; it is easy to absorb moisture, which greatly reduces the mechanical properties.
