Description

Reinforced corrugated carton

Technical Field

The invention relates to the field of packaging materials, in particular to a reinforced corrugated carton.

Background

The corrugated paper board is made into a corrugated paper box through die cutting, indentation, box nailing or box gluing. The corrugated case is a packaging product with the widest application, and the use amount is always the first of various packaging products. For more than half a century, corrugated cartons gradually replace transport packaging containers such as wooden boxes and the like with excellent service performance and good processing performance, and become the leading force of transport packaging. It not only protects the goods, is convenient for storage and transportation, but also beautifies the goods and publicizes the goods. The corrugated case belongs to green environmental protection product, and it does benefit to the environmental protection, does benefit to the loading and unloading transportation.

Although the corrugated box has a series of advantages as described above, the following problems still remain in use:

(1) compared with packaging containers such as wooden boxes and plastic boxes, the corrugated case is lower in cost, but is easy to deform due to extrusion and collision in the transportation and placement processes due to lower material strength, articles in the case can be damaged, and the transportation safety cannot be guaranteed;

(2) when using corrugated box to transport article such as egg, fruit, need set up the baffle between the article more to prevent collision each other between the article and produce the damage, but only play the separation effect through placing a corrugated sheet between article at present, because the corrugated sheet position is unset, consequently in the transportation, corrugated container board can't guarantee the stability of article position, still can not avoid collision each other between the article.

In order to make up the defects of the prior art, the invention provides a reinforced corrugated carton.
