Use for the preparation of labels for "roller-fed" applications of a heat-shrinkable non-axial multilayer film, formed from at least three layers, the core containing component a) selected from ethylene with a1) isotactic crystalline polypropylene and / or a2) a crystalline copolymer of propylene and 4 It comprises component b) selected from b1) amorphous atactic polypropylene and / or b2) an amorphous propylene-ethylene copolymer with at least one alpha-olefin having to 12 carbon atoms, wherein, in% by weight with respect to the total amount of monomer, 1a; The total amount of component b) in scales by weight per 100 scales in terms of weight of component a) is between 3 and 12, the outer skin layers contain a copolymer of ethylene and propylene and at least one C4-C12 alpha-olefin, the film is by means of linear synchronous motors achieved by simultaneous biaxial stretching, heat shrinkage in MD is between 8 and 17% and TD? is ¤2, multilayer film thickness is between 25 and 35 µm; film yield is ¥ 95%; spillages in the label application line, ¤ 0.5%; The label application process on containers involves the application of labels affixed with hot melt adhesive to containers that have a convex lateral surface of the container that is larger than 74 mm where the upper edge of the label is applied and has a radius of curvature of the surface greater than 72 mm to which the lower edge of the label is applied. The label height, measured along the vertical axis of the container, is approximately 60 mm. |
