Partitioned breathable packaging bag

Abstract

The invention provides a partitioned breathable packaging bag. The front side and the rear side of a packaging bag main body are provided with a first additional bag body and a second packaging bag body. The first additional bag body is arranged on the front side of the packaging bag main body and is of a foldable structure, the first additional bag body and the front end of the packaging bag main body are integrally arranged through first additional bag tearing lines, and the first additional bag tearing lines are provided with first additional bag tearing line puling heads. The second additional bag body is arranged on the rear side of the packaging bag main body and is of a foldable structure, the second additional bag body and the front end of the packaging bag main body are integrally arranged through second additional bag tearing lines, and the second additional bag tearing lines are provided with second additional bag tearing line pulling heads. A buffering and supporting layer is arranged between a first paper layer and a second paper layer and internally provided with elastic supporting components, and the buffering and supporting layer further contains fiber filler. By means of the partitioned breathable packaging bag, different articles can be contained in a partitioned manner, and waterproof and breathable functions are achieved.

Description

technical field [0001] The invention relates to the technical field of packaging, and more specifically, relates to a partitioned air-permeable packaging bag. Background technique [0002] Packaging bags refer to bags used to pack various supplies, making the goods convenient to transport and store during the production and distribution process. Widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags are eventually transported to landfills for disposal like general garbage, and only 7% of plastics are recycled. [0003] The packaging bags in the prior art usually have a sealed structure, which cannot meet the storage and transportation of raw materials that require ventilation. The following problems: the one, directly through the hole, it is easy for foreign matter to enter the bag, causing contamination of the contents; the other is for the solid of the powder, it will cause leakage. [0004] However, due to the poor shapin...

AI Technical Summary

Problems solved by technology

[0003] The packaging bags in the prior art usually have a sealed structure, which cannot meet the storage and transportation of raw materials that require ventilation. The following problems: First, direct through holes, easy to make foreign substances enter the bag, causing pollution of the contents; second, for solid powder, it will cause leakage

[0004] However, due to the poor shaping effect of the paper bag, it is easy to damage the wrapped items. Now there is a paper packaging bag with a fiber layer between the double-layer papers on the market. Without the cushioning and support of other structures, it is very easy to deform under the action of extrusion, failing to achieve the original design purpose, and still causing damage to the items inside

[0005] Moreover, the existing paper packaging bags have only one storage space, and only two paper packaging bags can be used for commodities that need to be stored separately, which will cause a certain amount of waste invisibly and is not conducive to environmental protection.
