摘要：
The present invention relates to a film having a combination of good flexibility and excellent barrier properties. The film comprises at least one barrier layer. The barrier layer comprises at least 5 percent, by weight of the layer, of an anhydride and/or carboxylic acid functionalized ethylene/alpha-olefin interpolymer having a density in the range of from 0.855 to 0.900 g/cm
3 ; and having a melt index (190°C/2.16 kg) of greater than 200 g/10 min. The barrier layer further comprises at least 60 percent, by weight of the layer, of an interpolymer derived from ethylene and vinyl alcohol monomer units.
