Abstract

Un método para elaborar una película exfoliable comprende el proporcionar una película de capa multiple; exfoliar la película en una primera porcion y una segunda porcion; tratar la segunda porcion para aumentar su permeabilidad al gas; y relaminar la segunda porcion hacia la primera porcion. En otro aspecto de la invencion, un aparato para elaborar una película exfoliable comprende un medio para exfoliar una película en una porcion y una segunda porcion; un medio para tratar la segunda porcion para aumentar su permeabilidad al gas; y un medio para relaminar la segunda porcion tratada hacia la primera porcion. Las perforaciones, perforaciones parciales y otros tratamientos de película se pueden hacer, y de este modo se utilizan ventajosamente en conexion con una segunda porcion permeable al gas preferentemente de una película exfoliable sin afectar a una primera porcion impermeable al gas preferentemente de la misma película.
