CA 2311499

A heat-shrinkable film, which is useful in the manufacture of bags with a good balance of mechanical, optical and shrink properties and improved sealability, comprises an outer heat-sealing layer of a heat- sealable polyolefin, an outer abuse layer comprising a polyamide with a melting temperature >= 180 °C, and an intermediate layer comprising a polyamide with a melting temperature lower than 165 °C. The bags thus obtained can suitably be heat-sealed also when overlapped.

La présente invention concerne un film thermorétractable utilisé dans la production de sacs, présentant un bon équilibre de propriétés mécaniques, optiques et rétractables ainsi qu'une étanchéité améliorée. Ce film comprend une couche externe thermoscellable constituée d'une polyoléfine thermoscellable, une couche externe indicatrice d'effraction comprenant un polyamide dont la température de fusion est >/= 180 DEG C, et une couche intermédiaire comprenant un polyamide dont la température de fusion est < 165 DEG C. Les sacs ainsi obtenus peuvent être thermosoudés, de manière appropriée, même lorsqu'ils se chevauchent.
