PREPARATION METHOD OF BLEND FILM USING RECYCLED WASTE POLYVINYLALCOHOL AND BLEND FILM OBTAINED THEREBY

摘要

PURPOSE: A method for preparing a blend film using recycled waste polyvinylalcohol and a blend film obtained thereby are provided to prepare a PVA blend film at an inexpensive cost by using waste polyvinylalcohol instead of atactic PVA and blending with starch. CONSTITUTION: A method for preparing a blend film using recycled waste polyvinylalcohol comprises the steps of: blending starch with waste polyvinylalcohol non-woven fabric and dissolving the blended material in water; and forming a membrane using the blend solution. The polyvinylalcohol non-woven fabric has numerical average polymerization of 1,000~2,000, alternating array dyad group content of 50~55%, and saponification degree of 80.0~99.9%.
