▎ 摘  要

NOVELTY - A polymer composition comprises 32-58 wt.% polymer A, 4-20 wt.% polymer B, and 32-58 wt.% polymer C, where polymer A is the most polar among polymer A, polymer B and polymer C; where the polymer C is the least polar among the polymers; where the polymer B has the lowest oxygen permeability among the polymers; and where the polymer composition has oxygen permeability lower than that of binary blend polymers A and C. USE - A polymer composition for polymer film or sheet used for preparing plastic material and/or plastic packaging (all claimed). ADVANTAGE - Oxygen, water vapor and/or hydrocarbon permeability of plastic material and/or plastic packaging are reduced. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for reducing oxygen, water vapor and/or hydrocarbon permeability of plastic material and/or plastic packaging which involves incorporating the composition or the polymer film or sheet in the plastic material and/or plastic packaging.
