PVA water soluble wrapping film

PVA water-soluble bags/wrapping films are made of polyvinyl alcohol (PVA) that can dissolve in water. They are used for packaging

micro-fibers and structural macro-fibers in concrete.Currently, they are widely used in the market and have gained industry recognition.

The use of PVA water-soluble bags/wrapping films offers the following advantages:

1.Convenient Mixing Process: Water-soluble bags can be directly mixed with concrete since they rapidly dissolve in water.

This makes the mixing process more convenient,eliminating the need for additional bag handling steps.

2.Even Fiber Dispersion: The use of water-soluble bags ensures the uniform dispersion of fibers in concrete.

As the bags dissolve completely in water, fibers are free to release into the concrete,preventing issues related to uneven distribution.

3.Reduced Environmental Pollution: Water-soluble bags are eco-friendly packaging materials that leave no residue after dissolution in water.

In comparison to traditional plastic bags,water-soluble bags contribute to reducing environmental pollution.

4.Improved Concrete Quality: By ensuring the uniform dispersion of fibers, water-soluble bags contribute to enhancing the quality and performance of concrete.

The even distribution of fibers strengthens concrete's mechanical properties, such as strength and toughness.

5.Simplified Process: The use of water-soluble bags simplifies the concrete mixing process, reducing reliance on manual labor and improving overall production efficiency.

This is particularly crucial for large-scale construction projects.
