company news about The advantages and limitations of pva water soluble films

PVA water-soluble film is a biodegradable film material mainly composed of polyvinyl alcohol (PVA). When exposed to water, it can quickly dissolve and disperse at a certain temperature and within a specific time, leaving no solid residue.

Advantages

• Precise dosing (no leftover packaging).

• Reduces plastic waste.

• Safe handling of hazardous chemicals.

• Environmentally friendlier than conventional plastics.

Limitations

• Sensitive to moisture—needs sealed packaging during storage.

• Can be more expensive than regular plastic films.

• Mechanical properties (strength, flexibility) are lower than some traditional plastics.
