Abstract
A continuous film that includes ethylene copolymer selected from the group consisting of ethylene vinyl acetate, ethylene n-butylacrylate carbon monoxide, ethylene vinyl acetate carbon monoxide, and combinations thereof. The film exhibits a moisture vapor transmission rate of at least 100 g/m2/day when measured according to MVTR Test Method I.
Claims22
A continuous film consisting essentially of ethylene vinyl acetate having a melt index of at least 50 g/10 min at 190° C., said film exhibiting a moisture vapor transmission rate of at least 100 g/m2/day when measured according to MVTR Test Method I.
