Patent ID: 8424273

Claim:
A thermoformable, heat-sealable and heat-shrinkable multilayer film comprising a central inner layer (I) having two sublayers (Ia and Ib), and formed of at least one thermoplastic polymer with a VICAT softening point of 65° C. or below, and the following sequence of layers on each side of the central inner layer: an adhesive promoter layer (H 1 ) formed of at least one polymer having a melt flow index (MFI) in the range of 0.1-2.0 g/10 min, optionally a gas barrier layer (B) formed of a thermoplastic polymer, optionally a further adhesive promoter layer (H 2 ), and a heat-sealable surface layer (S), said multilayer film having longitudinal and transverse heat-shrinkabilities of at least 20% at 93° C. each, which heat-shrinkabilities are each reduced by less than 10% by thermoforming.
