Abstract
The composite material according to the invention having low resistance to tearing and good mechanical strength and puncture resistance comprises at least: a) a mechanically strong outer plastic film, preferably biaxially oriented and printed, selected for example from polyester, polyamide and polyolefin and preferably metallized; b) a highly adhesive layer, preferably in the form of an extruded coating, selected for example from the low- density polyolefins; c) a soft layer imparting tearability preferably selected from: c') a sublayer of coextruded and microperforated ethylene copolymers; c'') a nonwoven film; d) a layer substantially similar to layer b). In a preferred embodiment an additional polyolefin film is applied.
