Improved flexible EVOH for high performance films

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 has a density in the range of 0.855 to 0.900 g / cm3 of at least 5 weight percent of the layer and a melt index (190 ° C./2.16 kg) greater than 200 g / 10 minutes. Contains anhydrides and / or carboxylic acid functionalized ethylene / alpha olefin interpolymers. The barrier layer further comprises an interpolymer derived from ethylene and vinyl alcohol monomer units of at least 60 weight percent of the layer. [Selection] Figure 1
