<p>Multi-layer heat-shrinkable films in which at least one layer (A) is based on a polyolefin composition comprising a propylene copolymer and having particular crystallinity characteristics, and at least one layer (B) comprises a linear compolymer of ethylene with one or more alpha -olefins (LLDPE). The films are characterized by an optimum balance of physicomechanical properties, processability and sealability at low temperatures.</p> |
