Sandwich Structure Foam Composite Packaging Box

Abstract

The invention discloses a foam composite packaging box with a sandwich structure. The foam composite packaging box comprises a bottom layer composite aluminum or magnesium alloy thin plate, a side thin plate, a connecting sub plate, structured foam, a top layer composite aluminum thin plate, a V-shaped groove and a packaging box main body, wherein the bottom layer composite aluminum thin plate is cross-shaped; the cross-shaped structured foam is fixedly bonded and connected on the bottom layer composite aluminum thin plate; the area of the structured foam is smaller than the area of the bottom layer composite aluminum or magnesium alloy thin plate; and the parts, on which the structured foam is not bonded, of the bottom layer composite aluminum or magnesium alloy thin plate are the side thin plate and the connecting sub plate. Compared with the prior art, the foam composite packaging box with the sandwich structure has the beneficial effects that the strength is high, the weight is light, buffer and shock absorption effects are achieved, the problems that packaging boxes in the market are low in structure strength or are high in strength and high in weight, and high-end magnalium boxes are high in cost are solved, the production technology is simple, and the box further has heat preservation and shielding functions as the middle and surface of a product are the structured foam and the metal with quite low thermal conductivity.

Description

technical field [0001] The invention relates to a packaging box, in particular to a sandwich structure foam composite packaging box. Background technique [0002] The packaging box products currently on the market mainly include aluminum alloy materials as the skeleton, ABS, MDF (medium fiber board), plywood (multi-layer board); magnesium aluminum alloy; direct injection molding of ABS or PE PC plastic; these products exist The following problems: (1) The product is too heavy and so on.
