PURPOSE: Provided is a resin composition which effectively blocks oxygen and has advantages of excellent plasticity, compatibility and flexibility, by applying the composition to a blocking layer for film, sheet or a bowl. CONSTITUTION: A resin composition comprises 45 wt.% to 80 wt.% of ethylene-vinylacetate copolymer (EVOH) containing 10 mol% to 50 mol% of ethylene and having saponification to be higher than 95; 10 wt.% to 52 wt.% of polyolefin; and, 3 wt.% to 30 wt.% of an oxygen blocking resin composition. The oxygen blocking resin composition is prepared by polymerizing 50 wt.% to 95 wt.% of degenerated partly saponificated resin (PHEVA) out of ethylene-vinylacetate copolymer (EVOH) containing 50 mol% to 95 mol% of ethylene and having saponification to be higher than 20 or the mixture of the PHEVA and more than one unsaturated acids, and 50 wt.% to 95 wt.% of the degenerated polyolefin containing the PHEVA and an unsaturated acid derivative. |
