Description

Carton sandwich structure with strong bearing capacity

Technical Field

The utility model relates to the technical field of packaging, in particular to a carton sandwich structure with strong bearing capacity.

Background

Corrugated cartons are widely used in the fields of daily life and industrial production. The existing corrugated case is of a laminated structure, each layer is of an integral structure, and the layers are integrated by gluing. The corrugated carton is simple in production process and relatively low in cost. But has the defects of easy deformation, low cycle utilization rate and the like. To improve the mechanical strength of a carton, increase the recycling rate, and change the transition from a force-removing configuration to an independent press-receiving configuration in a conventional corrugated paper product.

Some existing corrugated cases are generally sealed by using adhesive tapes, the adhesive tapes are required to be torn off when the seals are opened, and the structures at the sealing positions of the corrugated cases are easily damaged, so that the integral structures of paper products are deformed, and the service lives of the paper products are greatly shortened. The damaged carton can not be reused, needs to be recycled and reproduced, and increases the labor cost and the manufacturing cost.
