The ton bag is made of polyolefin resin through wire drawing and weaving process, and then cut into cylindrical or sheet-shaped substrates of different sizes after coating, and then the substrates are sewn into round or square bags according to the design requirements product.
We will introduce the usability and sealing of ton bags for you:
1. Usability of ton bags. When designing the ton bag, it is necessary to fully consider the purpose and usage of the ton bag, such as lifting, transportation, and loading material performance. In addition, it is necessary to consider whether the packaged items in the ton bag are edible, otherwise it should be non-toxic and harmless to food.
2. The tightness of the ton bag. If the materials packaged in the ton bag are different, the requirements for the sealing performance are also different. Such as powder, poisonous, and polluted items, etc. have very strict requirements on sealing performance, and the air tightness requirements of ton bags for items that are prone to moisture or mildew cannot be ignored. Therefore, when designing the ton bag, it is necessary to consider the influence of the base fabric lamination process and the sewing process on the sealing.
