<p><P>PROBLEM TO BE SOLVED: To provide a metallized film having a multi-layered structure. <P>SOLUTION: The metallized film has a tie layer comprising 5-50 wt.% of a mixture (A) and 95-50 wt.% of a polypropylene homopolymer or copolymer. The mixture (A) comprises (1): 5-100 wt.% cografted mixture of (C1)+(C2) obtained by cografting the mixture of (C1)+(C2) with an unsaturated carboxylic acid or its functionalized derivative wherein (C1) is 90-20 wt.% of a metallocene polyethylene having 0.865-0.915 relative density and (C2) is 10-80 wt.% of a non-metallocene LLDPE, or a polypropylene homopolymer or copolymer, and (2): 95-0 wt.% of (D) a polyethylene selected from a polyethylene homopolymer or copolymer and elastomers. The mixture (A) has (a) 30-10<SP>5</SP>ppm of the content of a grafted unsaturated carboxylic acid and (b) 0.1-30 g/10 min of a melt flow index (MFI) by ASTM D 1238 at 190°C/2.16 kg. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
