BOTTLE EXCELLENT IN RECYCLABILITY AND METHOD FOR RECYCLING THE BOTTLE

摘要

A bottle excellent in recyclability which has a laminate structure comprising a main resin material layer and at least one layer of a glycolic acid based polymer; and a method for recycling the bottle which comprises crushing the bottle, washing the resulting crushed product with an alkaline water, water or an acidic water, to thereby remove the layer of a glycolic acid based polymer, and recovering the main resin material. The bottle combines good gas barrier property due to the glycolic acid based polymer and excellent recyclability, and the method for recycling can be practiced with good efficiency.
