Integrated plastic bag multilayer combination

Abstract

The invention discloses an integrated plastic bag multilayer combination, and relates to the technical field of plastic bags. The integrated plastic bag multilayer combination comprises a plurality oflayers of integrated plastic bags which are distributed in a jacket layer mode, each layer of the integrated plastic bags is of an integrated structure, fillers for preventing interlayer adhesion fill the space between every two adjacent layer of the integrated plastic bags, every two adjacent layers of the integrated plastic bags are concentrically aligned and closely attached and sealed, the side wall or the bottom of an accommodating cavity of an integrated plastic bag multilayer combination body is provided with a volume standby area, the volume standby area is used for releasing the available volume when the integrated plastic bag is lifted away from a storage barrel, the edge area of the integrated plastic bag multilayer combination body is provided with a sealing mechanism, and theedge area of the integrated plastic bag multilayer combination body is provided with a lifting handle mechanism. The integrated plastic bag multilayer combination has the beneficial effects that rawmaterials are saved, the damage rate is low, the volume utilization rate is high, and the occupied space for storing and carrying is low.

Description

technical field [0001] The invention relates to the technical field of plastic bags. Background technique [0002] Known existing plastic bags, such as shopping bags, garbage bags and other bags, are formed by crimping of planar plastic films or tubular plastic films. [0003] In the prior art, for example, China Utility Model Patent No. 201720791280.1 discloses a convenient-to-use multi-layer structure disposable environmental protection garbage bag, which adopts the technical solution of the sleeve garbage bag, and the garbage bag starts to be used from the innermost layer. One layer can be taken out, and the remaining garbage bags can continue to be used in the garbage can without repeated bagging, which is very convenient to use. But there are also certain problems in its use.

Problems solved by technology

However, there are certain problems in its use

[0004] 201720791280.1-"A convenient-to-use multi-layer structure disposable environmental protection garbage bag" The garbage bag is not a one-piece structure, and its crimping edge is not smooth, and it is prone to wrinkles and gaps when multi-layer tacking

The accumulation of layers of wrinkles and gaps reduces the usable volume of the inner garbage bag and is prone to breakage

On the other hand, garbage bags with a secondary crimping structure will produce corner waste during the production process; in addition, when the secondary crimping structure is expanded into a three-dimensional cavity, irregular corners or folds will appear, which will also reduce volume utilization.
