A foam plastic packaging box

Abstract

The invention relates to a packaging box made of foamed plastic. The packaging box comprises a foam box body, a plastic support frame and a foam cover body, wherein the plastic support frame is mounted on the outside of the foam box body; the foam cover body is mounted at the upper end of the foam box body; and the plastic support frame comprises an annular baseplate, fan-shaped plates, support rods, an annular clamping plate and clamping blocks. According to the packaging box, through the combination of the foam box body and the plastic support frame, the strength of the foam box body is improved, so as to increase the use efficiency and service life of the foam box body; the foam cover body is fixed in a position-limiting manner, so that the separation between the foam cover body and thefoam box body, which can affect the packaging quality of the foam box body, is prevented when the stress is large; and the distance between the foam box body and the horizontal plane is increased through the plastic support frame, and the force of friction between the foam box body and the horizontal surface is reduced, thereby improving the service life of the foam box body.

Description

technical field [0001] The invention relates to the field of packaging processing, in particular to a foam plastic packaging box. Background technique [0002] The raw material of the foam box is expandable polystyrene foam, which is a new type of shockproof packaging material. Because of its light specific gravity, impact resistance, easy molding, beautiful shape, bright color, high efficiency and energy saving, the insulation material is low in price. Wide range of uses and other advantages, so it is widely used in the field of packaging. Foam boxes are box-type packaging containers made of foam plastics. Plastic foam is plastic with many tiny pores inside. Foam boxes are often used for fruit transportation and item packaging. encapsulation. [0003] In the process of packaging and transporting items through foam boxes, due to the limitations of the physical properties of foam boxes, the following problems exist in the actual operation process: [0004] (1) The strength ...

AI Technical Summary

Problems solved by technology

[0004] (1) The strength of the traditional foam box is weak, and it is easy to be damaged and corroded during transportation and handling, resulting in a low utilization rate of the foam box and a large waste of the foam box

[0005] (2) The traditional foam box is easily subjected to external force during transportation, resulting in the phenomenon that the box body and the box cover are separated, which causes the items in the foam box to leave the foam box due to external force, thus being hit
