Abstract:
A multi-layer polymer film comprising a core layer and a sealing layer, said sealing layer comprises a propylene copolymer composition, said propylene copolymer composition has a comonomer content in the range of 3.0 to 8.0 wt.-%, the comonomers are C 5  to C 12  α-olefins, comprises a polypropylene (A) and a polypropylene (B) in the weight ratio [(A)/(B)] of 20/80 to 80/20, wherein  said polypropylene (A) has a comonomer content of equal or below 4.0 wt.-%, the comonomers are C 5  to C 12  α-olefins, and said propylene copolymer (B) has a comonomer content of 4.0 to 20.0 wt.-%, the comonomers are C 5  to C 12  α-olefins.

Claim (Index 16):
Process for producing a multi-layer polymer film comprising:\n providing a core layer (CL) selected from the group consisting of polyvinyl alcohols, polyacrylates, polyamides, poly(ethylene terephthalate), polyolefins (PO) and mixtures thereof, a sealing layer (SL), and optionally an outer (OL), a further sealing layer (SL) or a metal layer (ML) wherein: (a) the core layer (CL);\n (a1) is coated on the one side with a propylene copolymer composition (P) obtaining a sealing layer (SL); and \n (a2) optionally;\n (a2-i) is on the other side coated with a polyolefin (PO) obtaining an outer layer (OL); or \n (a2-ii) is on the other side coated with a propylene copolymer composition (P) obtaining a second sealing layer (SL); or \n (a2-iii) is on the other side metallized obtaining a metal layer (ML), wherein; \n \n (b) said propylene copolymer composition (P);\n (b1) has a comonomer content in the range of 3.0 to 8.0 wt. %, the comonomer is C 6  \u03b1-olefin, \n (b2) comprises a polypropylene (A) and a polypropylene (B) in the weight ratio [(A)/(B)] of 35/65 to 50/50, wherein \n said polypropylene (A) is a propylene homopolymer (H-A) or a propylene copolymer (C-A) having a comonomer content of below 4.0 wt. %, the comonomers are C 5  to C 12  \u03b1-olefins, and \n said propylene copolymer (B) has a comonomer content of 4.0 to 20.0 wt. %, the comonomer is C 6  \u03b1-olefin, and \n (b3) fulfills the ratio MFR (A)/MFR (P)<1.0 \n wherein MFR(A) is the melt flow rate MFR 2  (230\u00b0 C.) [g/10 min] measured according to ISO 1133 of the polypropylene (A), MFR(P) is the melt flow rate MFR 2  (230\u00b0 C.) [g/10 min] measured according to ISO 1133 of the propylene copolymer composition (P), and \n (b4) has a xylene soluble content (XCS) determined at 25\u00b0 C. according to ISO 16152 of below 16.0 wt. %; \n (b5) a melting temperature Tm determined by differential scanning calorimetry (DSC) of at least 135\u00b0 C., and \n (b6) a heat sealing temperature (SIT) of equal or below 115\u00b0 C., and \n (b7) is free of any elastomeric polymer component, and \n wherein the multilayer polymer film is cast and not subjected to a stretching step.
