Ton bags are packaging products that we often use. Due to their good packaging performance, they play a very good role in the transportation and protection of goods, so they are now loved by many merchants and consumers. However, with the increasing number of manufacturers making large bags on the market, the quality of large bags has become uneven and difficult to choose. Many friends don’t know how to distinguish the quality of large bags. The editor below will teach you. Everyone distinguishes the quality of ton bags.
Ton bag is a kind of flexible transportation packaging container, which has the advantages of moisture-proof, dust-proof, radiation-resistant and strong. When designing a tonnage bag, first understand the weight of the cargo and determine the volume of the tonnage bag according to the specific gravity of the packaged material. It also depends on whether the loaded material is sharp and solid block material. If so, the base fabric should be a little thicker when designing the big bag, on the contrary it can be thinner. When designing the ton bag structure, the strength of the regular waistband in the national standard should reach more than twice the strength of the base fabric, but the design effect is not good in practice. Because the base fabric and the waistband have different strengths, the base fabric will crack first.
In the design, the waistband and the base fabric should be made of base fabric with the opposite strength to prevent this problem. For large bags, consider the anti-aging function of the suture and the effect of the suture on the tensile strength of the base fabric. When packaging powders, toxic, and fear-of-purification items, the sealing problem must be dealt with first. Therefore, in practical design, the ton bag is sewn with thick threads and fine needles or non-woven fabrics and base fabrics to improve the sealing performance. In addition, when sewing ton bags, it is requested that the suture select a polyester thread with a strength of more than 18kg to ensure that its sewing strength reaches the national standard.
