Title
(EN) HIGH MOISTURE BARRIER OPP FILM CONTAINING HIGH CRYSTALLINITY POLYPROPYLENE AND TERPENE POLYMER
(FR) FILM DE POLYPROPYLENE ORIENTE CONSTITUANT UNE BARRIERE TRES EFFICACE CONTRE L'HUMIDITE, CONTENANT DU POLYPROPYLENE A HAUTE CRISTALLINITE ET UN POLYMERE TERPENIQUE
Abstract
(EN)
An oriented film structure of improved water vapor transmission rate is prepared from an extruded and stretched mixture of (1) high crystallinity polypropylene (HCPP) having intermolecular stereoregularity greater than 93 % and (2) a moisture barrier improving amount of polyterpene resin.
(FR)
Un film à structure orientée présentant une vitesse de passage diminuée de la vapeur d'eau est réalisé à partir d'un mélange extrudé et étiré (1) d'un polypropylène hautement cristallin ayant une stéréorégularité intermoléculaire supérieure à 93 % et (2) d'une quantité de résine polyterpène suffisante pour améliorer les propriétés de barrière contre l'humidité.
