A heat-shrinkable polypropylene film adapted to be printed with, particularly, a flexographic ink is disclosed, which comprises a single layer heat-shrinkable film comprizing a polypropylene resin composition containing spherical silicone resin fine particles of 0.2 to 5 microns in average particle size in a content of 0.1 to 0.7 % by weight or a multi-layer heat-shrirnkable film wherein at least one of the surface layer comprises said polypropylene resin composition, with at least one surface of the single layer film or one surface of the surface layer of the multi-layer film having been subjected to corona discharge treatment to such degree that wettability index of the treated surface becomes 36 to 42 dyn/cm.

Cette invention concerne une pellicule de polypropylène thermorétrécissable adaptée particulièrement à l'impression flexographique. Il s'agit d'une pellicule monocouche thermorétrécissable formée d'une composition de résine de polypropylène et de fines particules sphériques de résine de silicone ayant une taille moyenne comprise entre 0,2 et 5 micromètres pour une teneur en poids de 0.1 à 0,7 % ou d'une pellicule thermorétrécissable multicouche dont au moins une des couches extérieures est formée de la composition susmentionnée, au moins une face de la pellicule monocouche ou une face de la couche extérieure de la pellicule multicouche ayant été soumise à un traitement par effet couronne propre à situer son indice de mouillabilité entre 36 et 42 dyn/cm.
