Shock-proof and break-proof packaging box

Abstract

The invention relates to a shock-proof and break-proof packaging box, and belongs to the technical field of packaging. The shock-proof and break-proof packaging box is composed of upper layer foam, aplastic frame and lower layer foam. The plastic frame has a flat H-shaped cross section, the upper layer foam is connected and fixed to the upper part of the plastic frame, and the lower layer foam isconnected and fixed to the lower part of the plastic frame. A storage groove is formed in the middle part of the upper layer foam. The shock-proof and break-proof packaging box has a novel structure,a clear preparation principle and a simple method, and an integrated structure is constituted by the plastic frame, the upper layer foam and the lower layer foam. Compared with a conventional foam packaging box, the shock-proof and break-proof packaging box solves the problems of low plasticity and low strength of the conventional foam box, the strength of the foam is increased, the anti-pressurecapability of the shock-proof and break-proof packaging box is improved, and the transportation demands of the shock-proof and break-proof packaging box are further met.

Description

technical field [0001] The invention belongs to the technical field of packaging, and relates to a packaging box and a manufacturing method thereof, in particular to a shockproof and breakage-resistant packaging box. Background technique [0002] Bubble packaging, simply put, is packaging made of foam. The so-called foam packaging mainly refers to the thermal processing of expandable polystyrene raw materials through molds, and the packaging products made are commonly known as "foam". Expandable polystyrene is an ideal packaging material. Through the molding process, it can be processed into packaging products of various shapes and thicknesses according to needs. In the case of high load, the material achieves the function of cushioning and shock absorption through deformation, energy absorption, and decomposition of energy, and also has the functions of heat preservation and heat insulation. EPS packaging products are generally white, and can be colored according to requi...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of existing traditional packaging foams, which have high plasticity but low strength, and the plastic deformation produced by the foam easily causes damage to the packaging shell and the product itself, and cannot meet the transportation requirements, the present invention proposes a shockproof and breakage-resistant packaging box and its manufacturing method. The structure is novel and the processing method is simple, which can solve the deficiencies of the above problems, increase the strength of the foam, improve the pressure resistance of the product, and further meet the transportation needs of the product
