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 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%.
