Abstract:
1. A multilayer laminated film for packages, constituted by a first layer made of plastic material and by at least one second layer made of material chosen among plastic material, metallic material, paper-like material or equivalent materials, each layer being coupled to the adjacent layer by means of an intercalated layer of adhesive material, said multilayer laminated film having, on at least one face of the more rigid layer of plastic material, a plurality of continuous, parallel, side-by-side incisions, which are suitable to facilitate a reduction of the breaking load at right angles to the direction of the incisions, said incisions affecting partially the thickness of said more rigid layer and being obtained by removing material by means of a mechanical operation, the thickness of said more rigid layer, at said incisions, being reduced with respect to the thickness of said more rigid layer outside said incisions, with intrinsic nature of the material of said more rigid layer material being unaltered, wherein said depth of the incisions is in a range between 15 and 85% of the thickness of the layer on which it is provided.
