Abstract:
The invention relates to a polypropylene composition which combines low sealing initiation temperature (SIT) and high melting point (Tm), thus having a broad sealing window.

Claim (Index 1):
A polypropylene composition being a binary blend comprising two propylene polymer fractions PPF1 and PPF2 in specific amounts:\n a) less than or equal to 50 wt % of propylene polymer fraction PPF1 being a propylene copolymer comprising propylene monomers and 1.50 to 7.00 mol % of one comonomer selected from C 4 -C 10  alpha-olefin and\n b) more than or equal to 50 wt % of propylene polymer fraction PPF2 being a propylene terpolymer comprising propylene monomers, 3.00 to 12.00 mol % of ethylene comonomer and 1.50 to 17.00 mol % of one comonomer selected from C 4 -C 10  alpha-olefin, characterized in that the polypropylene composition: \n i) has a melting temperature (Tm) in the range of 135 to 160\u00b0 C. as determined by DSC according to ISO 11357 \n ii) satisfies the equation:\n Delta= Tm \u2212SIT \n \n wherein Delta is in the range of 39 to 50\u00b0 C., and \n wherein Tm is the melting temperature, in \u00b0 C., of the polypropylene composition, SIT is the sealing initiation temperature, in \u00b0 C., of the polypropylene composition, as calculated from pellets via DSC analysis,\n the amount of PPF1 and PPF2 being relative to the total sum of the propylene polymer fractions PPF1 and PPF2.
