Foldable and recyclable express package box and manufacturing method thereof

Abstract

The invention relates to an express package box, comprising a box body, a box bottom and a box cover; the box body, the box bottom and the box cover are formed by integrally folding and molding a composite EPE panel, and the box body, the box bottom and the box cover respectively comprise an outer protective layer and an inner buffer layer; the inner buffer layers of the inner surfaces of the box bottom and the box cover are positioning bosses; the box body, the box bottom and the box cover are molded at one step by adopting hot pressing and die cutting processes, and each folded part is thinned by the hot pressing to extend to form a hinge; the edges of the box body and the box cover form a circle of wrapping edge through thermal forming and bending, a circle of positioning clearance exists between the positioning bosses and the wrapping edge, and after the box body is molded, the upper and lower edges of the box body are respectively placed in the positioning clearance of the box body and the box cover. The express package box changes the current situation that most express package boxes can only be used once and the waste is severe, the use function of folding and circulation for multiple times is realized, and the express package box has the characteristics of high strength, convenience in box packaging operation and better sealing effect.

Problems solved by technology

The express industry produces a huge amount of packaging waste, causing serious waste of resources and environmental pollution

The problems existing in the existing express packaging boxes mainly include: 1. The material is mostly corrugated cardboard, which has poor cushioning performance and mechanical properties. During transportation, it is often deformed and damaged by external forces, and the safety is poor; Iron nails are fixed, and the lid and bottom of the box are glued with adhesive tape, which is not easy to disassemble, and most of them are for one-time use, so the utilization rate is low; 3. The function of the packaging box is single, and plastic packaging boxes generally cannot be folded and stacked, and the transportation cost for repeated use too high
