We all know that some bags, such as woven bags, may have gaps, and when some powder is loaded, it will inevitably leak out. At this time, the advantages of the ton bag are reflected, so how does the ton bag solve this problem?
Leak-proof design of ton bags
The raw materials of the ton bag: the base fabric and the sling should be improved, the stitching of the ton bag should be particularly strong, and reinforced sewing should be used. Ordinary sewing is enough to fold in half, and for enhanced sewing, fold in half, and sew twice and add hem. So that the ton bag will not be spread out due to the loose sewing.
The inside of the bag body can also be strengthened in the form of inclined rib to strengthen the firmness of the ton bag. Sometimes it is necessary to hold powder, such as mineral powder, medicinal powder, flour, etc. Generally, companies use machine air filling. Once the ordinary ton bag is filled with air, the powder will leak from the pores of the suture with the air flow. In this case, PE inner bag cannot be used.
Leak-proof design can only be used at the seam of the big bag: generally in the form of cotton sliver. can solve this problem very well.
