Abstract

A film having first segments and second segments arranged across the film's width direction is disclosed. The first and second segments are separated from each other by polymer interfaces. The first segments include a first polymeric composition and the second segments include a second polymeric composition. At least some of the second segments are layered second segments having first and second layers in the film's thickness direction, and one of the first or second layers includes a third polymeric composition different from the second polymeric composition. An extrusion die useful for making the film and a method for making the film using the extrusion die are also disclosed.
