Abstract

An object is to provide a barrier material which not only is high in degree of biomass and small in amount of COemitted, but also has biodegradability and simultaneously has excellent gas barrier property and water vapor barrier property, and which can be suitably used particularly in packaging applications for foods or the like, such as a packaging material, a bag, a paper container, a cardboard box, and a cup. A solution to be provided is a barrier material having an oxygen permeability of 10 ml/m·day·atm or less at a temperature of 23° C. and a relative humidity of 0%, and having a total degree of biomass of 50% or more.
