Polyvinyl Alcohol(PVOH, PVA, Or PVAl) Is A Water- Soluble Synthetic Polymer. Properties Polyvinyl Alcohol Has Excellent Film Forming,emulsifing And Adhesive Properties. It Is Also Resistant To Oil, Grease And Solvent . It Is Odorless And Nontoxic. It Has High Tensile Strength And Flexibility, As Well As High Oxygen And Aroma Barrier Properties. However These Properties Are Dependent On Humidity, In Other Words, With Higher Humidity More Water Is Absorbed. The Water, Which Acts As A Plasticiser, Will Then Reduce Its Tensile Strength, But Increase Its Elongation And Tear Strength. PVA Is
