BIODEGRADABLE SOY PROTEIN ISOLATE-BASED FILMS COATED WITH POLYLACTIC ACID

摘要

The present invention relates to a film made of a biodegradable soy protein coated with polylactic acid, wherein the flexible PLA coated SPI film of the present invention provides a simple coating method without the addition of any compatibilizer or chemical modification of the film surface. Was prepared through. The mechanical strength and water resistance of the PLA coated SPI films were greatly improved to the level of LDPE and cellulose acetate films, respectively. PLA coated SPI films will be suitable for applications in food packaging with high water activity or for use under high relative humidity conditions.;Soy protein, polylactic acid, biodegradable, coating film
