Abstract: Use of olefin-based plastic films for obtaining labels in rolls for high speed roll-fed applications from about 8,000 to about 75,000 containers/hour, the films having a thickness comprised between 10 and 22 ?m, flexural rigidity (N·mm) in the range 0.5×10?2-4.5×10?2 save for a constant 1/[12×(1??2)] wherein ? is the Poisson modulus, the elongation at break in MD determined according to ASTM D 882 lower than 130%, dimensional stability measured according to the OPMA TC 4 standard at 130° C. for 5 minutes in the air in MD comprised between 0 and ?10% and in TD between ?4 and +4%.

Abstract: Use for preparing labels for “roll-fed” applications of a heat shrinkable uniaxial multilayer film, formed of at least three layers, wherein the core comprises a component a) selected from a1) isotactic crystalline polypropylene and/or a2) a crystalline copolymer of propylene with ethylene, and component b) selected from b1) amorphous atactic polypropylene and/or b2) an amorphous propylene-ethylene copolymer with at least one alpha-olefin having from 4 to 12 carbon atoms wherein, as % by weight with respect to the total amount of monomers, 1a; the total amount of additive component b), in parts by weight per 100 parts by weight of component a) being comprised between 3 and 12, the external skin layers comprise a copolymer of propylene with ethylene and at least one C4-C12 alpha-olefin, the film being obtained by simultaneous biaxial stretching by means of linear synchronous motors.

Abstract: Use of olefin-based plastic films for obtaining for obtaining roll tapes for closing containers, the films having a thickness in the range from 10 to 22 ?m, flexural rigidity (N·mm) in the range 0.5×10?2-4.5×10?2 neglecting a constant 1/[12×(1?v2)] being v the Poisson modulus, an elongation at break in MD, determined according to ASTM D 882, lower than 130%, a dimensional stability, determined according to the OPMA TC 4 standard at 130° C. for 5 minutes in air in MD in the range from 0 to ?10% and in TD from ?4 to +4%.
