description An opaque, sealable and peelable film, including at least (a) a cavitated first core layer containing a thermoplastic polymer and a cavitating agent, (b) a second core layer containing a peelable blend and (c) one or more outer layers, at least one of which is a sealable outer layer, each independently containing a thermoplastic polymer. The peelable blend of the second core layer (b) may contain (i) from 20-80 wt % of a polyethylene and (ii) from 80-20 wt % of a polyolefin incompatible with polyethylene (i), or it may contain (i) from 10-35 wt % of ethylene- -olefin elastomer and (ii) from 90-65 wt % of propylene homopolymer.
