摘要
PURPOSE: A biodegradable multi-layer sheet and a manufacturing method thereof are provided to enhance shock resistance and heat resistance while keeping the biodegradation property.;CONSTITUTION: A biodegradable sheet comprises 50.0-85.0 parts by weight of polylactic acid, 10.0-30.0 parts by weight of poly(methyl methacrylate) selected from aliphatic poly(methyl methacrylate) based homopolymer or copolymers, and 5.0-20.0 parts by weight of rubber-modified vinyl-based graft copolymer resin. The sheet is composed of multi-layered structure of B / A / B. As A layer is an inner layer and is composed of rubber modified graft copolymer and polylactic acid, and the B layer is an outer layer and is composed of a mixture of polylactic acid and one or more of poly(methyl methacrylate) selected from polymethyl methacrylate group homopolymer or copolymers.;COPYRIGHT KIPO 2012
