In microcamadas component, method for producing a component in microcamadas, film and article

摘要

Summary "component in microcamadas, method for producing a component in microcamadas, film and article" the present invention refers to a component in microcamadas having permeability to oxygen and water vapor enhanced (i.Is reduced permeabilities) comprising a microcamada barrier of a semi crystalline polymer barrier in direct contact with a microcamada border so as to promote the formation of crystalline lamellae in the plan.A component in microcamadas having a significant amount of crystalline lamellae in the plan is characterized by having an improvement in permeability to oxygen of at least 1,5x and an improvement in permeability to water vapor of at least 1,5x.A component in microcamadas having an improvement of at least 1,5x in permeability to oxygen and water vapor may be coextrudado and subjected to stretching after extrusion or heat treatment.
