The ton bag is a kind of packaging commonly used in the transportation industry, and it is also the choice of packaging bags for many items. The production process of the container bag is very cumbersome, and it can be better used to ensure that the internal and external quality is up to standard. However, there are also cases where the surface of the container bag is uneven, and the reason for the uneven surface of the ton bag is formed.
The uneven surface of the big bag is mainly caused by the uneven tension between the warp and weft yarns. Uneven tension between warp and weft yarns will result in uneven surface of the woven bag. There are many steps in warp tension adjustment. The warp creel is the birthplace of the unbalanced warp tension. If the flat wire is wound on the shaft, the rotational resistance torque will be unbalanced, resulting in uneven tension.
