Big bags are a kind of packaging items that are now used in many transportation industries. It can pack and transport bulk and sandy products very well. Now with the continuous development of society, the requirements of ton bag manufacturers are constantly improving when producing container ton bags, and the technical control is becoming more and more strict. I hope that consumers and transportation Manufacturers can use very good bulk bags.
The quality of the ton bag is very important, ranging from carrying hundreds of kilograms to several tons. The tensile requirements far exceed those of ordinary woven bags. Therefore, the selection of materials is strict, especially when selecting tensile raw materials. Carry out the corresponding index test. Each big bag manufacturer has a different production ratio. The production of big bags cannot be composed of raw materials. In order to meet the needs of related products, various raw materials must be combined reasonably and scientifically. When planning the structure of the big bag, the relevant specifications stipulate that the strength of the waist hoop should be more than twice the strength of the base fabric, but in practice this design effect is not good, because the strength of the base fabric and the waist hoop are inconsistent, causing the base fabric to crack first. In planning, the base fabric material with the same strength as the base fabric can be used to avoid this problem
For large bags, the aging resistance function of the suture and the influence of the seam on the tensile strength of the base fabric should also be considered. When packing powder, poisonous, and items that are afraid of contamination, the sealing problem must be dealt with first. Therefore, in the practical plan, thick needles or non-woven fabrics are used to sew together with the base fabric to improve the airtightness.
