Problems needing attention in choosing ordinary woven bag packaging

When consumers face more and more woven bags in the market, they don't know how to choose woven bags. Which kind of woven bags is better?

1. We should control the material selection of base cloth

When designing woven bags, merchants should first understand the weight of the goods to be loaded in the woven bags, and then determine the volume of the woven bags according to the proportion of packaging materials, which also depends on whether the shape of the loaded materials is sharp and solid block materials. If so, thick bottom cloth should be selected when designing woven bags, but thin bottom cloth can be selected.

2. Check the strength of progressive flat wire

In order to ensure the strength of the base cloth, it is necessary to ensure the tensile strength of the progressive flat wire. The quality of raw materials per ton bag shall be strictly controlled. The woven bag shall select the wire drawing raw materials whose melt index reaches the consumption of international regular manufacturers.

3. Ensure boom selection

In the design of woven bag, the choice of sling is very important. The sling needs to meet the requirements of weaving density. When designing the suspender of woven bag, two rings and four rings can be used to increase the tensile strength.

4. Add additives to prolong its service life

In order to increase the aging resistance of woven bags in sunlight, a certain amount of anti violet agents and stabilizers should be added in the process of flat drawing, so as to prolong the service life of woven bags.

5. Structural design

For the structural design of woven bags, the National Code stipulates that the strength of the side waist should be more than twice that of the base cloth.

6. Sewing process design

Woven bags should also consider the anti-aging effect of sutures and the influence of stitches on the tensile strength of the bottom cloth. Therefore, thick or non-woven fabrics should be sutured together with the bottom cloth to increase the density.

7. Design of inlet and outlet

Practice has proved that the pressure received by the discharge port is relatively large, which can be a little higher, and the strength of the feed port can be reduced a little.
