Abstract
A film structure including: (a) at least one functionalized film layer, wherein the at least one film layer comprises a polar-reactive group polyolefin layer used as an internal layer in the film structure; and (b) a lamination adhesive composition present on, and in contact with, a least a portion of a surface of the internal layer; wherein the green tack value of the adhesive composition is greater than 0.772 Newtons/centimeter; a laminate including the above film structure bonded to a substrate layer; a process for producing the film structure; a process for producing the laminate; and a laminated article made from the above laminate.
