Abstract:
1. A polyolefin single or multi-layer film which comprises at least one core layer comprising a PP/PE random bipolymer in which the PE component comprises up to 50% by weight of the bipolymer; wherein the dynamic loss modulus (E″) of the film measured at 3 Hz and 25° C. is: from about 28 to about 136 MPa measured in the transverse direction (TD); and/or from about 73 to about 135 MPa measured in the machine direction (MD); and wherein the dynamic storage modulus (E′) of the film, measured at 3 Hz and 25° C. is (i) from about 630 to about 2800 MPa measured in the transverse direction (TD); (ii) from about 1300 to about 3000 MPa measured in the machine direction (MD).
