Reinforced sewing and leak proof design of the container bag
Flexible container bags generally contain 1 ton to 1.5 tons, and also have 2 to 3 tons, so the requirements for flexible container bags are even higher. The raw materials for flexible container bags: base fabric and sling To improve, the stitching of the flexible container bag should be particularly strong, and the stitching should be used. Ordinary sewing will be OK twice for the crease, and the stitching will be folded in half, and the seam will be twisted twice. The flexible container bag is not scattered because the sewing is not strong. The bag body can also be used to strengthen the container bag in the form of diagonal ribs. Flexible container bags sometimes need to contain powder, such as mineral powder, powder, flour, etc., the general enterprise uses the machine airflow filling, the ordinary container bag is filled by airflow, the powder will not follow the airflow from the suture The pores leak out, in which case the PE inner bag cannot be used. Leak-proof design can only be used in the seams of flexible container bags: it is usually stitched in the form of a sliver. Can solve this problem very well
