HIGH BARRIER LOW PROFILE FORMING WEB

摘要

64536-590 A forming web comprises a first extruded polymeric film oriented to substantially the same extent in both the longitudinal and machine directions. Alternately, a high molecular weight crystalline polyolefin is blown at least to a blow-up ratio sufficient to orient the film to substantially the same extent in both the longitudinal and transverse directions. A second extruded polymeric film including a layer of an oxygen barrier polymeric material may be laminated to the first film.
