Polymeric films having oxygen barrier properties. |
| 摘要 |
<p>A hydrolyzed ethylene-vinyl acetate copolymer film having low oxygen permeability is provided. The film is irradiated with ionizing radiation in an inert atmosphere at a dosage sufficient to provide a free radical concentration such that the film has an oxygen permeability of substantially zero cc-mil/m<2>-day-atm.</p> |
