Abstract
Description
technical field
[0001] The invention relates to a composite woven packaging bag, in particular to a high-barrier composite woven packaging bag. Background technique
[0002] Compared with small woven bags, packaging bags have the characteristics of large capacity, easy loading and unloading, labor saving and efficiency improvement. Most of the currently used packaging bags are made of a single PP woven cloth or PE woven cloth. However, the overall strength of this packaging bag is low, and the tensile resistance is poor, which cannot meet the needs of users.
[0003] Patent No. CN205802044U discloses a high-barrier composite woven packaging bag, which includes a packaging bag body, which in turn includes PE woven cloth, and EVOH films arranged on both sides of the PE woven cloth and connected by an adhesive layer. Although the packaging bag is easy to make and has certain tensile strength, its structural strength is still poor, and its oxygen barrier, moisture barrier and l...
