<p>The invention relates to transparent and stiff coextruded polypropylene blown films with ink-printable skin layer(s) bonded to the base or core layer without intermediate layers, whereby the core layer or base layer comprises at least 50 % of of at least one of a polypropylene homopolymer, a polypropylene random copolymer or a heterophasic polypropylene copolymer and the skin layer(s) consists (consist) of either a mixture of at least 50% of low density polyethylene and at least 10 % metallocene linear low density polyethylene and up to 5 % of common additives or a polypropylene random copolymer with a MFI between 0.8 and 3.0 g/10 min (ISO1133 at 230°C, 2.16 kg) mixed with up to 50% of a low density polyethylene, linear low density polyethylene or metallocene linear low density polyethylene, MFI 0,5 to 3,5 g/10min, and up to 5 % common additives. The films are useful for label applications and for lamination.</p> |
