1. What material are ton bags made of?

Answer: Ton bags are made of 100% pure new polypropylene.

2. How to deal with the problem of using breathable bags to filter river silt but the filtration is not clean? --

Answer: According to the type of silt, a layer of non-woven bag can be put inside the breathable bag to achieve a double filtering effect.

3. Can ton bags contain powder, which can be moisture-proof and keep the bag upright?

Answer: The bag shape of the ton bag is designed in U shape/4 pieces, and uses inner lining 14 wire lining + 23 wire baffle

4. The base cloth weight of the ton bag body cloth is generally between how many g/㎡.

Answer: 155-240 g/㎡ without film coating

5. What is the maximum width of the ton bag tube cloth?

Answer: The maximum width of the tube cloth is 260cm

6. Is the bag anti-ultraviolet added? How long can it be stored outdoors under high temperature exposure?

Answer: Our ton bags generally add 2% UV, and there is no problem with outdoor use for one year.

7. What is the mesh number of the breathable ton bag net?

Usually, the mesh number of the base cloth of the breathable ton bag with a gram weight of 150-180gsm is 15-18 mesh (the mesh number refers to the number of holes in 1 square inch)

8. In order to increase the load-bearing capacity of the bag and prevent the bag from tearing, how should the ton bag be designed?

1.2-1.5t, a 20-45g/m belt can be added to the top of the ton bag.

1.5-2t, a cross bottom can be designed

3.2-3t, a well bottom can be designed

9. What is the difference between a ton bag with a cross-angle sling and a ton bag with a side seam sling?

Answer: The load-bearing capacity of the two is different, and the overall weight is also different. The ton bag with a side seam sling has a stronger load-bearing capacity, a heavier bag weight, and a slightly higher price. You can choose different types of ton bags according to the items to be loaded.

10. Ton bags need to be waterproof. Is there any solution?

Answer: Ton bags can choose to add lining or use coated base cloth to achieve waterproof effects.

11. What should I do if the bag still leaks powder even though it has added leak-proof cotton strips?

A: Based on the mesh count of the powder, it is recommended to add non-woven fabric to all sewing points on the basis of leak-proof cotton strips to achieve a double leak-proof effect. The gram weight of the non-woven fabric is determined by the mesh count of the powder.

12. What are the core factors that affect the load-bearing capacity of ton bags?

(1) Raw materials: The quality and thickness of the woven polypropylene fabric used in the manufacturing process will significantly affect the load capacity. Fabrics with higher denier (thread thickness) can increase strength.

(2) Seams and stitching: The strength and method of stitching (such as single seam, double seam or reinforced seam) will affect the load-bearing capacity.

(3) Shape and size: The size and design (such as U-panel, round or baffle bag) will distribute the load in different ways and affect stability and capacity.

(4) Lifting rings: The location, number and strength of the lifting rings determine the bag's ability to support the load under lifting pressure.

(5) Usage environment/storage environment: Exposure to moisture, heat and UV radiation will degrade the polypropylene fibers and seams over time, thereby reducing strength.

13. What should we do if the top cover is torn when the ton bags are stacked for storage?

When the ton bags are stacked for storage, the top cover is torn because the base fabric of the top cover is too thin and cannot withstand the pressure. It is recommended that the top cover of the ton bag and the bag body use the same thickness of base fabric, which can withstand greater pressure and will not tear again.
