Ton bag manufacturers: Ton bag is a flexible transport packaging container, with moisture, dust, radiation, firm and other advantages. Can be widely used in chemical, building materials, plastics, mineral products and other powder, granular, block items packaging, is the storage and transportation industry's ambition products. Therefore, it is necessary for us to know more about the common sense of tons of bags to improve our ability to distinguish, and the following ton bag manufacturer Billion Ding will introduce you from four aspects:
1, monofilament strength
In order to ensure the strength of the tonnage base cloth, the tensile strength of the flat wire is increased. The strength of the flat wire should reach more than 0.4N/tex and the elongation should be 15-30%. In the practical production process, the amount of filler masterbatch needs to be strictly controlled, generally about 2%. If the masterbatch is increased too much or the recycled material is increased, the strength of the substrate will decrease. Therefore, the quality of the original data needs to be strictly controlled, and the original drawing data consumed by in-orbit manufacturers with melt index reaching the national standard is selected for tons of packets.

2. Structure planning
Ton bag manufacturers: When planning ton bag structure, the strength of the customary belt in the national standard should reach more than twice the strength of the substrate, but the planning effect is not good in practice. Because of the difference in strength between the backcloth and the belt, the backcloth will crack first. In the planning, the belt and the bottom cloth should use the opposite strength of the bottom cloth to avoid this problem.
3. Base material
When planning a ton bag, we must first understand the weight of the loaded goods, and determine the ton bag volume according to the specific gravity of the package. It also depends on whether the loaded data is sharp, solid block data. If so, the bottom cloth should be thicker when planning the ton package, and on the contrary, it can be thinner. In practice planning, the ton bag with a load of 500kg generally uses (150-170)G/m2 substrate, the longitudinal and transverse tensile strength of the substrate is (1470-1700)N/5cm, and the elongation is 20-35%. The weight of the ton bag exceeds 1000 kg. The base cloth is generally used (170~210)G/m2. The vertical and horizontal tensile strength of the base cloth is (1700-2000)N/5cm, and the elongation is 20~ 35%.
4. Sewing process
Ton bag manufacturers: Ton bag in addition to the sewing requirements in accordance with the national standard rules, but also demand
The anti-aging function of the suture and the effect of the suture on the tensile strength of the substrate were considered. In the packaging of powder, toxic, afraid of purification of items, the first to solve the sealing problem. Therefore, in practical planning, the ton bag is sewn with thick thread and fine needle or non-woven fabric and bottom cloth to improve the sealing. In addition, when sewing tons of bags, it is required to use polyester thread with a strength of more than 18kg to ensure that the sewing strength reaches the national standard.
