<p>At least mono-axially stretched polypropylene (PP) film (I) is claimed, contg. lubricant(s), antistatic additive(s) and antiblocking additive(s) (II); the novelty is that (II) contains poly(isobutyl methacrylate) (PIBMA) and poly(methyl methacrylate) (PMMA) polymers. More specifically (I) is transparent film; mol. ratio PIBMA:PMMA = (1.2:1)-(7.0:1); (I) contains 700-5000 ppm (II), pref. in the form of approx. spherical particles; (I) is a multilayer film with (II) only in one or both of the outer layers, pref. with a heat-laminating or sealing layer; pref., (II) is a copolymer of the corresp. monomers (IBMA and MMA), and is pref. crosslinked; (I) is subjected to corona, fluorine or plasma treatment. -</p> |
