Space bag type shipping sack

Abstract

A space bag type container bag, which includes a square bag body with an open upper part sewn from polymer material woven cloth, the upper part of the bag body is opened with the center line of the opposite side as the boundary to divide the left and right sides, The top suspension rings folded in half are sewn on the two edges respectively, the lower bottom surface of the bag body is sewn with a feed opening in the middle, and a tie is sewn on the discharge opening; Together, the two ends of the top ring are spread out and sewn around the upper open edge of the bag; the lower bottom of the bag is double-folded and double-sewed 2.5cm by wrapping the lower edge of the bag. After widening, it is sewn with two parallel lines; the connection between the lower material opening and the lower bottom is sewed with two lines through a single fold at the material opening and the lower bottom connection edge is not folded. A tie is sewed 20-30cm downwards from the mouth of the discharge port; it has the characteristics of simple structure, convenient manufacture and use, convenient loading and transportation of bulk materials, and improved shipping efficiency.

Description

technical field [0001] The invention relates to a space bag type container bag made of woven cloth made of polymer raw materials, which belongs to the technical field of container containers for bulk materials. Background technique [0002] In the prior art, conventional bulk materials need to be transported in container bags, but conventional container bags are sewn from cloth, but container bags made of such cloth lack fastness and can only be made into small Larger container bags are made by other methods, so the shipping efficiency of bulk materials is low, the service life is short, and it is easy to be damaged. [0003] Although the present patent bulletin discloses a container bag made of woven cloth made of polymer raw materials, which solves the collection and transportation of large-capacity bulk materials, and has high fastness and greatly increases the service life. There are defects such as inconvenient and low efficiency for collecting and transporting bulk ma...

AI Technical Summary

Problems solved by technology

[0002] In the prior art, conventional bulk materials need to be transported in container bags, but the conventional container bags are made of cloth, but the container bags made of this cloth lack fastness and can only be made into small Large-capacity container bags are made by other methods, so the shipping efficiency of bulk materials is low, the service life is short, and it is easy to be damaged

[0003] Although the present patent bulletin discloses that there is a container bag made of woven cloth made of polymer raw materials, which solves the collection and transportation of large-capacity bulk materials, and has high fastness and greatly increases the service life, but because of the unreasonable design of the production structure, it is still There are defects such as inconvenience and low efficiency in collecting and transporting bulk materials
