Woven bag

Abstract

The invention discloses a woven bag, and relates to the field of packaging materials. The woven bag disclosed by the invention has a cylindrical woven bag body, the upper end and the lower end of the woven bag body are provided with openings, the woven bag body consists of a waterproof layer, a composite layer and a printing layer from the inner side to the outer side, the waterproof layer is formed by polymerization of metallocene and polyethylene, and the composite layer is formed by composite weaving of kraft and plastic knited mesh. The woven bag body can obstruct water molecules from penetrating, has waterproof and dampproof functions, and has good flexibility, penetration resistance and shock resistance; the woven bag body has stronger mechanical property, so as to bear strong stress generated when articles are put in the woven bag and when the bag is moved; the outer side of the woven bag is provided with the printing layer, so a user can conveniently print cargo information on the printing layer; the woven bag is practical, convenient and suitable for popularization and use.

Description

[0001] technical field [0002] The invention relates to the field of packaging materials, in particular to a woven bag. [0003] Background technique [0004] Woven bags are a kind of packaging supplies used to pack various goods, and are widely used in the packaging of chemical fertilizers, grains, pesticides, seeds, salt, and chemical products. Most of the woven bags on the existing market only have one layer of plastic woven bags. During the process of bagging and moving, the bag body is often damaged, resulting in leakage of the goods. Moreover, the woven bag itself is not waterproof, and it is easy to cause rice noodles in a humid environment.

Problems solved by technology

Most of the woven bags on the existing market only have one layer of plastic woven bags. During the process of bagging and moving, the bag body is often damaged, resulting in leakage of the goods. Moreover, the woven bag itself is not waterproof, and it is easy to cause rice noodles in a humid environment. Such as food or chemical products are damp and deteriorated, the application number is 201220451192.4 A new type of composite woven bag film, using polypropylene resin material for three-layer composite, used to solve the problem of poor mechanical properties of existing woven bags, but still can not meet the requirements of food , chemical fertilizers and other products have moisture-proof requirements, and the goods in the bag cannot be directly seen
