         12 . A film for packaging a product, comprising
 a protective layer and   a polypropylene-based multilayer polyolefin film comprising an inner heat sealable sub-layer comprising a propylene/ethylene copolymer blended with at least two different polyethylene polymer resins each selected from the group comprising an ethylene/octene copolymer, linear low density polyethylene, low density polyethylene, high density polyethylene, ethylene vinyl acetate, and ethylene methyl acrylate,   wherein the polypropylene-based multilayer polyolefin film does not fracture when exposed to a temperature in a range of about −20° C. to about 0° C. and the polypropylene-based multilayer polyolefin film layer does not melt or burst when exposed to a temperature of up to about 105° C.   
     
     
         13 . The film of  claim 12 , wherein the polypropylene-based multilayer polyolefin film further includes a core sub-layer adjacent to the inner heat sealable sub-layer and an outer skin sub-layer formed from at least one polyethylene polymer resin. 
     
     
         14 . The film of  claim 13 , wherein the core sub-layer includes a polymeric material having a melting point of at least 71° C. and the core sub-layer comprises a homopolymer polypropylene and a polyethylene polymer resin. 
     
     
         15 . The film of  claim 14 , wherein the homopolymer polypropylene of the core sub-layer has a melt flow rate in a range of about 0.5 g/10 min. to about 25 g/10 min. 
     
     
         16 . The film of  claim 14 , wherein the outer skin sub-layer includes a homopolymer polypropylene having a melt flow rate in a range of about 0.5 g/10 min. to about 25 g/10 min. 
     
     
         17 . The film of  claim 12 , wherein the polypropylene-based multilayer polyolefin film further includes a core sub-layer adjacent to the inner heat sealable sub-layer and an outer skin sub-layer formed from at least one polyethylene polymer resin, the core sub-layer comprises a homopolymer polypropylene and a polyethylene polymer resin, the outer skin sub-layer includes a homopolymer polypropylene and at least one of the at least two different polyethylene polymer resins of the inner heat sealable sub-layer includes a polyethylene-octene copolymer. 
     
     
         18 . The film of  claim 17 , wherein the protective layer is formed from a polyethylene terephthalate film. 
     
     
         19 . The film of  claim 18 , wherein the protective layer has a thickness in a range of about 0.1 mil to about 3.0 mil. 
     
     
         20 . The film of  claim 19 , wherein the protective layer has a thickness in a range of about 0.38 mil to about 1.0 mil. 
     
     
         21 . The film of  claim 18 , wherein an adhesive layer is used to laminate the protective layer to the outer skin sub-layer. 
     
     
         22 . The film of  claim 12 , wherein the propylene/ethylene copolymer has a melt flow rate in a range of about 0.5 g/10 min. to about 45 g/10 min. 
     
     
         23 . The film of  claim 22 , wherein the propylene/ethylene copolymer contains an ethylene comonomer in an amount in a range of about 1% to about 8% by weight of the copolymer. 
     
     
         24 . The film of  claim 22 , wherein at least one of the at least two different polyethylene polymer resins of the inner heat sealable sub-layer has a melt index in a range of about 0.50 g/10 min. to about 20 g/10 min.
