Water soluble PVA films are generally plasticized with multi '-OH' groups containing small molecules. Film's tensile properties are depend on the moisture in the film which is always in equilibrium with atmospheric moisture. Thus, film tensile & other functional properties are depend on Environmental moisture.

Anybody, guide me how do I make the film less moisture sensitive?? or How to maintain the moisture in the film in dry condition??

Thanks & Regards,
