CROSS DIRECTIONAL ZONED BICOMPONENT FILMS, FILM LAMINATES, AND SYSTEMS AND METHOD FOR MANUFACTURE OF THE SAME |
摘要 |
Coextruded films provide cross directional zoned multiple components side- by-side to one another. Systems and methods relate to coextruding such films. During coextrusion, a first polymer conjoins with a second polymer while a temperature differential is maintained between the first and second polymers. This temperature differential is selected to reduce a difference between the viscosities of the first and second polymers making the viscosity of the first polymer close enough to the viscosity of the second polymer to avoid separation upon coextrusion. Further, the films may form a layer in subsequent lamination to other material layers. |
