A composition comprises a matrix of an ethylene-vinyl alcohol copolymer having dispersed therein a drying agent in a particulate state. The volume-area average diameter of the grains of the drying agent having a long diameter of not less than 10 mu m is not greater than 30 mu m. A multi-layer structure comprises layers of such a composition. Gas barrier property of the multi-layer structure is hardly reduced after a retort treatment and thus, the multi-layer structure is extremely useful for packaging of food, expecially packaging of retorted food. |
