Detailed Introduction:

Material Properties

Biodegradability: PVA is a biodegradable polymer material that can be decomposed into carbon dioxide and water by microorganisms in natural environments. Therefore, after dissolving in water, it will not remain for a long time like traditional plastics, causing environmental pollution.

Low toxicity: PVA itself has very low toxicity to the human body and the environment. After dissolving in water, it will not release toxic and harmful substances, and will not cause harm to water quality and aquatic organisms.

Dissolution process

Physical dissolution: The dissolution of PVA water-soluble film in water is a physical process that does not undergo chemical reactions, does not produce new chemicals, and therefore does not cause chemical pollution to water quality.

Dissolution rate: The dissolution rate of PVA water-soluble film is relatively slow. After dissolving in water, it will gradually disperse in the water without forming sediment or suspended solids, and will not affect the transparency and clarity of water quality.

practical application

Environmentally friendly packaging materials: PVA water-soluble film is widely used in the field of environmentally friendly packaging, such as food packaging, drug packaging, etc. After dissolving in water, it will not pollute the packaging contents or cause harm to the environment.

Wastewater treatment: PVA water-soluble film is also used in wastewater treatment. After dissolving in water, it will not interfere with the wastewater treatment process, but can be removed through biodegradation, which helps to improve the efficiency of wastewater treatment.

In summary, PVA water-soluble film, after dissolving in water, generally does not affect water quality and is an environmentally friendly and safe material.
