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 µm, flexural rigidity (N.mm) in the range 0.5x10 -2 -4.5x10 -2 neglecting a constant 1/[12x(1-½ 2 )] being ½ 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%. |
