Abstract: A multilayer thermoshrinkable film and a process for manufacturing the same are described. The film is particularly suitable for packaging applications, in particular as a packaging thermoshrinkable hood for enclosing an item or a secondary packaging essentially consisting of polyethylene. The multilayer thermoshrinkable film of the invention comprises: a) at least one first film layer comprising a linear ethylene copolymer having a density of 0.920 to 0.950 g/cm; b) at least one second film layer comprising a first copolymer of propylene with ethylene and/or at least one CH2?CHR1 ?-olefins, where R1 is a hydrocarbon radical having 2-10 carbon atoms; and c) at least one third film layer comprising a linear ethylene copolymer having a density of 0.920 to 0.950 g/cm; wherein said at least one first film layer is arranged between said at least one second film layer and at least one third film layer.
