Vacuum-hammock shock-proof sleeve

Abstract

The invention provides a vacuum-hammock shock-proof sleeve. The sleeve comprises buffer walls, an accommodating space and an internal packaging film, wherein the buffer walls are formed by arranging a plurality of gas columns; the accommodating space is formed by combining a plurality of buffer walls in a connecting way and is in an enclosed state; and the internal packaging film is used for coating a wrapping material in a vacuum pumping mode and is arranged in the accommodating space and hung on the buffer wall. The shock-proof sleeve can realize a dual protection function on the wrapping material and solves the problem of poor protection effect on the wrapping material because the shock-proof sleeve is easy to pierce and causes gas leakage in the prior art.

Description

technical field [0001] The invention relates to the technical field of packing sleeves, in particular to a vacuum hammock type shockproof sleeve capable of achieving the functions of shock absorption and anti-collision. Background technique [0002] The traditional way of cushioning packaged items is mostly to protrude a plurality of raised small airbags on a plastic sheet, and to achieve the shock-absorbing and buffering effect by wrapping the plastic sheet of this structure on the outer periphery of the item. However, due to the limited shock-absorbing ability of the small airbag, the effect of buffering and shock-absorbing cannot be achieved for larger vibration or impact loads. Therefore, a kind of cushioning material using a gas packaging sleeve as a covering has been developed. [0003] Gas packaging sets use gas as the buffer medium for items, thereby providing buffer protection for items. However, the items are inevitably shaken or collided during the handling proce...

Problems solved by technology

[0004] The purpose of the technical solution of the present invention is to provide a vacuum hammock type anti-vibration cover, which can play a double protective role for the package, and solve the problem that the prior art anti-shock cover is easy to be punctured to cause gas leakage, and the protection effect on the package is not good.
