Metallized multilayer film

A metallized multilayer film comprising:

• 1) a first component comprising:
• (a) a core layer comprising a high crystallinity polypropylene homopolymer with an intermolecular stereoregularity greater than 93%;
• (b) a first skin layer adjacent to said core layer wherein said skin layer comprises high density polyethylene;
• (c) a vacuum deposited aluminum layer adjacent to said first skin layer;
• and
• 2) a second component comprising a polymer selected from at least one of low density polyethylene, EVA, EMA and EAA that is extrusion laminated to said aluminum layer of said first component at a web tension sufficient to prevent metal crazing of said vacuum deposited aluminum layer.

A metallized multilayer film comprising:

• 1) a first component comprising:
• (a) a core layer comprising a high crystallinity polypropylene homopolymer with an intermolecular stereoregularity greater than 93%;
• (b) a first skin layer adjacent to said core layer wherein said skin layer comprises a thermoplastic selected from a group consisting of ethylene vinyl alcohol copolymer, and amorphous polyamide;
• (c) a tie layer adjacent to said first skin layer comprising maleic anhydride modified polypropylene homopolymer or copolymer;
• (d) a vacuum deposited aluminum layer adjacent to said first tie layer layer;
• and
• 2) a second component comprising a polymer selected from at least one of low density polyethylene, EVA, EMA and EAA that is extrusion laminated to said aluminum layer of said first component at a web tension sufficient to prevent metal crazing of said vacuum deposited aluminum layer.

• and
• (e) a second skin layer adjacent to said core layer and on a side of said core layer opposite said first skin layer, said second skin layer comprising a polyolefin selected from the group consisting of ethylene-propylene random copolymer, ethylene-propylene-butylene terpolymer, propylene-butylene copolymer, and ethylene-propylene impact copolymer.
