Abstract

The invention provides a packaging bag capable of being rapidly expanded and closed. A express bag comprises a bag shell, bag lining plates, a zipper and a sealing belt. Through the special designs that the left lining plate and the right lining plate can rotate by 90 degrees in the bag and the front lining plate is transversely divided into two lining plate bodies up and down at the middle, and with the addition of the corresponding contracting and expanding method, the bag can be rapidly expanded into a cuboid shape, and also can be rapidly contracted into a flat shape, so that recovering transportation after the packaging bag is used is facilitated.

Description

technical field [0001] The invention relates to the field of logistics, in particular to a packaging bag that can be quickly unfolded and collapsed. Background technique [0002] At present, the unfolding and folding of most recirculating express boxes is not very convenient. Some need to be inflated, and the revolving express boxes take a long time to unfold. The present invention realizes the fast unfolding and closing of the packaging bag through the special design of a cuboid packaging bag inner liner. Contents of the invention [0003] The technical problem to be solved by the present invention is that through the special design of the inner liner of the packaging bag, the packaging bag can be quickly unfolded and folded, and the bag has a simple structure and low cost. [0004] In order to solve the above technical problems, the present invention provides a packaging bag that can be quickly unfolded and folded. The packaging bag is in the shape of a cuboid and inclu...
