在高阻隔性聚合物出现之前，氧敏感食品包装几乎是玻璃和金属容器的专属领域。共挤和定向与这些高阻隔树脂相结合，使许多新的市场可利用塑料包装。乙烯-乙烯醇共聚物树脂提供了最好的氧气阻隔性能的这些聚合物的物理，化学，和这些树脂的阻隔性能进行了审查，包括水分对其气体阻隔性能的影响。提供了一个描述的应用和类型的包装，这些共聚物树脂现在已经成为可能。
Oxygen sensitive food packaging was almost the exclusive domain of glass and metal containers until the advent of high barrier polymers. Coextrusion and orienta tion have combined with these high barrier resins to make many new markets avail able to plastics packaging. Ethylene vinyl alcohol copolymer resins provide the best oxygen barrier properties of these several polymers—the physical, chemical, and bar rier properties of these resins are reviewed, including the effects of moisture on their gas barrier properties. A description is provided of the applications and types of packages which these copolymer resins have now made possible.
