In the production of ton bag container bags, the selection of slings is essential. The sling must meet the weaving density requirements. Tonnage bag container bag When making a sling, you can use two-ring or four-ring to increase the tensile strength. To ensure the strength of the base fabric, the ton bag container must increase the tensile strength of the flat yarn. In the actual production and processing process, the container bag needs to strictly control the amount of the filler masterbatch, which is generally about 2%. If the masterbatch is added too much, or if the recycled material is added, the strength of the base fabric will be lowered.
