influencing factors

Storage environment: PVA water-soluble film should be placed in a cool, dry, and ventilated environment, avoiding direct sunlight and moisture.

 If the storage environment is improper, such as high temperature, high humidity, or direct sunlight, it may lead to a decrease in the performance of the film, thereby shortening its shelf life.

Packaging method: The packaging method of PVA water-soluble film can also affect its shelf life.

 Generally speaking, using sealed packaging can extend its shelf life.

Precautions

Avoid moisture absorption: PVA water-soluble film is prone to moisture absorption in humid environments, so attention should be paid to moisture prevention during use and storage.

Check performance: Before using PVA water-soluble film, check whether its performance is affected, such as transparency, flexibility, solubility, etc.

 If the performance is significantly affected, it may be necessary to replace the film.

The shelf life of PVA water-soluble film is usually 3-5 years.
