摘要：A multi-layer polymeric structure suitable for packaging foodstuffs has mainouter polymeric layers (1, 2) between which a moisture-sensitive, oxygen barrier layer (3)is embedded, layer (3) being ethylene-vinyl alcohol or polyvinyl alcohol polymers andbeing adhered to the outer layers (1, 2) by polymeric adhesive (4, 5). To protect layer (3)
from degradation of its oxygen barrier qualitites by moisture, e.g. contained in afoodstuff or arising during sterilization, the polymeric structure incorporates dryingagents or desiccants most conveniently compounded with the polymeric adhesive (4,5).
