Polymeric structure having improved barrier properties and method of making same |
摘要 |
A polymeric structure having an oxygen barrier layer (e.g., ethylene-vinyl alcohol copolymer) is heated in the presence of moisture to improve its resistance to oxygen and moisture penetration. A drying agent is incorporated in the multi-layer structure to control the rate of water penetration to, and the amount of water in, the barrier layer.
