Telescopic environment-friendly flexible freight bag and preparation method thereof

Abstract

The invention discloses a telescopic environment-friendly flexible freight bag and a preparation method thereof. The preparation process of the telescopic environment-friendly flexible freight bag comprises the following steps of: selecting materials; drawing filaments; weaving cloth; weaving strings; cutting; sewing; examining and receiving; carrying out a hoisting test; and packaging. In use ofthe telescopic environment-friendly flexible freight bag disclosed by the invention, when the volume needs to be reduced, a first zipper strip and a second zipper strip are fixed through a first zipper puller; subsequently one end of a first horizontal string and one end of a first intersected string are fixed through a buckle; at the moment, the first horizontal string and the first intersected string are in an uptight state; the first zipper strip, the first zipper puller and the second zipper strip are not in an uptight state; in a similar way, the other two sides are subjected to the sameoperation; after the operation is ended, the volume of the telescopic environment-friendly flexible freight bag is reduced; meanwhile, the shrank position can be prevented from being opened after thevolume is reduced; a flexible freight bag body can have relatively good fire retardance characteristics by a first fire-retardant layer and a second fire-retardant layer which are arranged; fire generated by friction is prevented; potential safety hazards are reduced; and the service life of the telescopic environment-friendly flexible freight bag is prolonged by reinforcing weft bars and reinforcing warp bars which are arranged.

Description

technical field [0001] The invention relates to the technical field of container bag processing, in particular to a scalable environment-friendly container bag and a preparation method thereof. Background technique [0002] During the transportation of the goods, it is necessary to load and unload the goods up and down, especially for some grain, cement, chemical raw materials and other powder and granular product packaging bags, the loading and unloading of the goods often requires manual handling. At present, the lack of human resources and high labor costs lead to The cost of handling is high. Furthermore, the efficiency of manual handling is low, and more time is needed for handling, which is a waste of time. At present, large-capacity flexible container bags are widely used. They are easy to use, easy to load and unload as a whole, and durable. It has become a general-purpose packaging product. However, ordinary container bags cannot be changed according to the capacity...

[0002] During the transportation of the goods, it is necessary to load and unload the goods up and down, especially for some grain, cement, chemical raw materials and other powder and granular product packaging bags, the loading and unloading of the goods often requires manual handling. At present, the lack of human resources and high labor costs lead to The cost of handling is high. Furthermore, the efficiency of manual handling is low, and more time is needed for handling, which is a waste of time. At present, large-capacity flexible container bags are widely used. They are easy to use, easy to load and unload as a whole, and durable. It has become a general-purpose packaging product. However, ordinary container bags cannot be changed according to the capacity they contain. They can only be replaced with different sizes of packaging bags according to the items they carry. It is very troublesome. Some environmentally friendly container bags with telescopic structures are loaded It is easy to open the structure in the shrinking state after feeding the material, which is not conducive to the real-time control of the user according to the use. At the same time, the physical strength of the environmental protection container bag needs to be improved, and the environmental protection container bag does not have good flame retardant properties. After friction, it is easy to cause spontaneous combustion and fire, which may cause large losses and pose a safety hazard
