Abstract
The present invention relates to an oxygen barrier film and container comprising ethylene-acrylate copolymer, more precisely an oxygen barrier film and container comprising ethylene-acrylate based copolymer composed of 10-50 mol % of ethylene monomer and 50-90 mol % of acrylate based monomer and having the weight average molecular weight of at least 30,000 g/m. The present invention provides an oxygen barrier film and container having excellent mechanical properties including flexibility, stretchability, glass transition temperature, anti-absorptiveness and Rockwell hardness and other characteristics such as oxygen barrier property and transparency as well.
