Abstract:
1. A process for obtaining roll tapes for closing containers wherein polyolefin-based plastic films having a thickness in the range from 10 to 22 μm; a flexural rigidity (N·mm) in the range of 0.5×10 −2 -4.5×10 −2 neglecting a constant 1/[12×(1−v 2 )], v being the Poisson modulus; an elongation at break in MD, determined according to ASTM D 882, lower than 130%; and 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%, are used.
