High strength, tensile strength, and tear resistance

Using thickened PP woven fabric (conventional 120–180g/㎡, heavy-duty ≥180g/㎡), with a base fabric tensile strength of ≥3000N/5cm, it is suitable for friction and puncture resistance against sharp edges and corners of gravel and debris, and is resistant to repeated lifting and pulling, making it less prone to bag breakage.

Acid and alkali resistant, chemically stable

With a pH tolerance range of 4–10, it can be used to contain building materials such as cement, fly ash, mineral powder, and lime, and is not easily corroded or embrittled by powder materials.

Temperature and weather resistance, anti-aging

The outdoor-specific model is added with UV anti-ultraviolet agent, suitable for temperature differences of **-40℃~80℃**. It is not prone to become brittle and crack under exposure to sunlight and rain in the open air, making it suitable for outdoor storage scenarios on construction sites.

Lightweight, foldable and recyclable

Empty bags can be folded and stored with minimal space occupation, and can be reused for 5-10 times. After being discarded, they can be recycled, with a cost much lower than that of iron drums and wooden boxes.
