Introduction
We have successfully mass produced polyvinyl alcohol (PVA) film using its own film-forming technology, combined with advantage of producing its raw material, PVA resin, on its own. Polyvinyl alcohol film is one of the important raw materials applied in polarizing films, release films and packaging films.
