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 mum, flexural rigidity (N·mm) in the range 0.5×10-2-4.5×10-2 save for a constant 1/[12×(1-nu2)] wherein nu 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%.
