High-barrier composite woven packaging bag

Abstract

The invention discloses a high-barrier composite woven packaging bag. The high-barrier composite woven packaging bag comprises a packaging bag body, wherein the packaging bag body comprises a woven outer barrier layer, a first PE waterproof layer is arranged in the outer barrier layer, an anti-cutting layer is arranged in the first PE waterproof layer, the anti-cutting layer is connected with a connecting adhesive film, the connecting adhesive film is connected with a second PE waterproof layer, and a lining layer is arranged in the second PE waterproof layer; a handle and an inlet are arranged at the top of the packaging bag body, an inlet cover is arranged at the inlet, first adhesive cloth is arranged along the edge of the inlet cover, and second adhesive cloth is arranged on the packaging bag body corresponding to the edge of the inlet cover; and a mobile phone bag is arranged on the circular-arc-shaped inlet cover, so that the performance of oxygen resistance, moisture resistance, light resistance and the like of the woven packaging bag is effectively improved, and the using effect is better. Due to the design of a reinforcing layer, the structure of the bag body is firmer and more reliable, the overall impact resistance is good, the toughness is good, and the connecting adhesive film plays a role in stretching, so that the bag body has certain stretching shrinkage resistance; and a mobile phone is prevented from falling off and is convenient to use.

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...
