Precautions For Use And Storage Of PVA Film


Polyvinyl Alcohol (PVOH) Film is sensitive to temperature and relative humidity (RH). Users should monitor and control room conditions during storage and film conversion.

Polyvinyl Alcohol Films are sensitive to ambient temperature and relative humidity. The film should be stored in its original air-tight protective wrap. Ideal storage conditions are 5 – 25°C (41 – 77°F) and 20 – 50%RH. Temperature excursions above 40°C/104⁰F for long periods should be avoided. The film should be conditioned in the protective wrap at the temperature of the converting environment for 48 hours prior to use. For additional information, contact solubpack Technical Service.

If the film is not completely used during conversion, the film should be repackaged in the air tight moisture barrier wrapping (typically HDPE) and stored properly until resuming conversion.
