Water-soluble films are specialized polymeric materials, most commonly made from polyvinyl alcohol (PVA or PVOH), that are designed to dissolve completely and safely when they come into contact with water. These films are widely used as an eco-friendly and convenient alternative to traditional plastics as they are biodegradable, non-toxic, and leave no harmful residues or microplastics after dissolution. The market is driven by increasing demand for sustainable packaging solutions, particularly in sectors such as household detergents, personal care, and agriculture.
