Title
(EN) FILM FORMED FROM A THERMOPLASTIC POLYMERIC RESINOUS BLEND
(FR) FILM FORME A PARTIR D'UN MELANGE DE RESINES POLYMERES THERMOPLASTIQUES
Abstract
(EN)
A thermoplastic film and container made from a chlorinated polyethylene blend. The composite film may be formed of a multilayer structure, in which a skin layer is formed of the chlorinated polyethylene resin blend. The composite multilayered structure is such that quietness is imparted without detracting from the extrudability and other physical characteristics necessary or practical applications. A vapor barrier may be included as a core layer. A particular application for the present invention is an ostomy bag.
(FR)
Film thermoplastique et conteneur fabriques a partir d'un melange de polyethylene chlore. Le film composite peut etre forme d'une structure multi-couches, dans laquelle une couche superficielle est formee du melange de resine de polyethylene chlore. La structure composite multi-couches obtenue est silencieuse sans pour autant diminuer les caracteristiques d'extrusion et autres caracteristiques physiques necessaires aux applications pratiques. Une barriere aux vapeurs peut etre inclue sous forme de couche centrale. Une application particuliere de la presente invention est un sac d'ostomie.
