The present invention is a high biomass, CO 2 emissions are low, furthermore, it has a biodegradability, and is a barrier material that combines excellent gas barrier and water vapor barrier properties, in particular packaging materials such as food, bags, paper containers, cardboard boxes, An object of the present invention is to provide a barrier material that is suitably used for packaging purposes such as cups. As a solution to the above problems, the present invention provides a barrier material having an oxygen permeability of 10 ml/m 2 ·day·atm or less at a temperature of 23° C. and a relative humidity of 0%, and an overall biomass of 50% or more. . |
