HIGH BARRIER POLYPROPYLENE COMPOSITIONS AND THEIR USE IN PACKAGING APPLICATIONS.

摘要

Film is provided wherein at least one layer comprises polymer, a molecular majority of which is derived from propylene, having water vapor transmission rate of less than or equal to about (-7.4428 g x 'mu'm/m2 x day x % polymer crystallinity) (% polymer crystallinity) + 627.32 g x 'mu'm/m2 x day, or (-0.0189 g x mil/100 in2 x day x % polymer crystallinity) (% polymer crystallinity) + 1.593 g x mil/100 in2 x day.
