Patent

CA 2320128

The invention related to a multi-layer, scalable biaxially oriented polypropylene film consisting of a base layer and at least one scalable covering layer. The base layer contains between 1 and 15 weight % of a resin with a mean molecular weight Mw of between 600 and 1,500 and between 1 and 6 weight % of a wax with a mean molecular weigh Mn of between 200 and 700. The n-heptane insoluble part of the polypropylene of the base layer has a chain isotactic index of at least 95 %, as measured by 13C-NMR spectroscopy. The invention also relates to a method for producing said film and to its use.

L'invention concerne un film de polypropylène multicouche, scellable et à orientation biaxiale, constitué d'une couche de base et d'au moins une couche de revêtement scellable. La couche de base contient entre 1 et 15 % en poids d'une résine d'un poids moléculaire moyen Mw de 600 à 1500, et entre 1 et 6 % en poids d'une cire d'un poids moléculaire Mn de 200 à 700. La fraction, insoluble dans le n-heptane, du polypropylène de la couche de base présente un indice d'isotaxie en chaîne d'au moins 95 %, mesuré par spectroscopie RMN au C<13>. L'invention concerne également le procédé de production de ce film et son utilisation.
