What is the role and use of polyvinyl alcohol
Coating on PE, PP and other heat-sealing substrates, greatly improving the oxygen barrier properties of the film. It is an important coating material that realizes singularization, lightweighting and demetalization of packaging materials. It is a method and means for realizing food packaging materials to meet the material performance requirements of packaging materials while promoting the packaging industry to move towards environmental protection and recyclability.
Polyvinyl alcohol can be used in the fields of textile slurry, vinylon fiber, coating agent for papermaking, architectural coatings, adhesives, PVA film, PVB raw materials, food and medicine, etc. PVA can also be used as a soil improver, polymer suspending agent and emulsifier. , Quenching agent, etc. In addition, as people continue to develop and improve the performance of PVA, its use continues to expand.
