Use of polyolefin-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 ranging from 10 to 22 µm, flexural rigidity (N.mm) in the range 0.5x10 -2 -4.5x10 -2 neglecting a constant 1/[12x(1-v 2 )] wherein v 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%. |
