Unlike a simple plastic bag that is as simple as a normal plastic bag, it requires a combination of multiple processes and other components.
The main factors affecting the stitching strength are the variety and type of suture, the size of the stitch, the stitches, the curling or crimping seam to the edge of the bag, the hot cutting and cold cutting methods.
In general, container production companies should develop internal control objectives for these impact factors. The tensile strength of the main body of the container bag must reach 67% of the fundamental strength, and the tensile strength of the bottom joint must reach 42% of the fundamental strength. Regarding the upper seal of the socket cement bag, it is advocated to treat the strength of the same seam bottom. The strength of the bottom direction of the paper bag is usually not up to the target, so it is proposed to be changed to the bottom bag. Regarding the laminating cold-cut bag, it is advocated to use the crimping treatment, since the cold-cut marginal stitching may be torn out from the warp yarn together with the weft. Regarding the woven bag with no strength requirement, the upper end of the woven bag is locked for one week, the stitch length can be dense, and the line can be thin.
The quality of the container bag generally depends on the person, equipment, raw materials, operating methods, and production environment.
1. Personnel problem：The personnel problem mainly reflects the sense of responsibility and technical proficiency of the employees.
2. Equipment problem: The aging of the production of the container bag, the poor drying and bag feeding techniques, etc. all lead to various problems such as sticking during the production of the bag.
3. Raw material problem: Raw material problems, including the quality of the ink, the uniformity of the agitation, the quality of the bag, or problems with the offset, can cause problems in printing.
