Abstract
A composition comprising a matrix of an ethylene-vinyl alcohol copolymer having dispersed therein a granular drying agent in a particulate state, wherein the volume-area average diameter of the grains of drying agent having a long dia meter of not less than 10.mu. is not greater than 30.mu.. A multi-layer structure comprising layers of such a composition. The gas barrier property of the multi-layer structure is not substantially reduced after a retort treatment and thus, the multi-layer structure is extremely useful for packaging of food, especially packaging of retorted food.
Claims8
A composition comprising a matrix of an ethylene-vinyl alcohol (EVOH) copolymer having dispersed therein a granular drying agent in a particulate state, wherein among the dispersed grains of drying agent, the volume-area average diameter of the grains having a long diameter of at least 10.mu. is not greater than 30.mu. and the ratio of EVOH to said drying agent ranges from 97:3 to 50:50.
A multi-layer structure comprising a layer of a composition comprising a matrix of an ethylene-vinyl alcohol (EVOH) copolymer having dispersed therein a granular drying agent in a particulate state, wherein among the dispersed grains of drying agent the volume-area average diameter of the grains having a long diameter of at least 10.mu. is not greater than 30.mu. ratio of said drying agent used in said composition is 3 to 50 wt%.
