Poly- hydroxy alkane acid copolymer and poly- lactic acid content composition for foaming material

摘要

As for this invention, as for this composition poly- hydroxy alkane acid copolymer, it includes poly- lactic acid and blowing agent in the foaming material in regard to available poly- hydroxy alkane acid copolymer and the poly- lactic acid content composition, fixed tensile strength, break point extension and expansion ratio, and completely it possesses the quality which biodegradation is done, can be applied by packing field widely.
