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 DEG C, and an intermediate layer comprising a polyamide with a melting temperature lower than 165 DEG C. The bags thus obtained can suitably be heat-sealed also when overlapped. |
