Abstract: front page image
(EN)The present invention relates to a polyethylene composition comprising: a) at least 45% to at most 95% by weight of a metallocene-catalyzed polyethylene A, wherein % by weight is based on the total weight of the polyethylene composition; wherein polyethylene A has a density of at least 0.916 g/cm3 to at most 0.940 g/cm3 The present invention relates to a polyethylene composition comprising: a) at least 45% to at most 95% by weight of a metallocene-catalyzed polyethylene A, wherein % by weight is based on the total weight of the polyethylene composition; wherein polyethylene A has a density of at least 0.916 g/cm3 to at most 0.940 g/cm3, as measured according to ISO 1 183-2:2004 at a temperature of 23 °C; and a melt index MI2 of at least 1.5 g/10 min to at most 4.0 g/10 min, as measured according to ISO 1 133 Procedure B at a temperature of 190 °C and a load of 2.16 kg; b) at least 5% to at most 55% by weight of a metallocene-catalyzed polyethylene B, wherein % by weight is based on the total weight of the polyethylene composition; wherein said metallocene-catalyzed polyethylene B comprises b1 ) at least 45% to at most 75% by weight of a metallocene-catalyzed polyethylene B1, wherein % by weight is based on the total weight of the metallocene-catalyzed polyethylene B; wherein polyethylene B1 has a density of at most 0.918 g/cm3, as measured according to ISO 1 183-2:2004 at a temperature of 23 °C; and a melt index MI2 of lower than the melt index MI2 of polyethylene A, as measured according to ISO 1133 Procedure B at a temperature of 190 °C and a load of 2.16 kg; and b2) at least 25% to at most 55% by weight of a metallocene-catalyzed polyethylene B2, wherein % by weight is based on the total weight of the metallocene-catalyzed polyethylene B; wherein polyethylene B2 has a density higher than the density of polyethylene B1, as measured according to ISO 1 183-2:2004 at a temperature of 23 °C; and wherein the melt index MI2 of polyethylene B2 is higher than the melt index MI2 of polyethylene B1, as measured according to ISO 1 133 Procedure B at a temperature of 190 °C and a load of 2.16 kg. The present invention relates to a polyethylene composition comprising: a) at least 45% to at most 95% by weight of a metallocene-catalyzed polyethylene A, wherein % by weight is based on the total weight of the polyethylene composition; wherein polyethylene A has a density of at least 0.916 g/cm3 to at most 0.940 g/cm3, as measured according to ISO 1 183-2:2004 at a temperature of 23 °C; and a melt index MI2 of at least 1.5 g/10 min to at most 4.0 g/10 min, as measured according to ISO 1 133 Procedure B at a temperature of 190 °C and a load of 2.16 kg; b) at least 5% to at most 55% by weight of a metallocene-catalyzed polyethylene B, wherein % by weight is based on the total weight of the polyethylene composition; wherein said metallocene-catalyzed polyethylene B comprises b1 ) at least 45% to at most 75% by weight of a metallocene-catalyzed polyethylene B1, wherein % by weight is based on the total weight of the metallocene-catalyzed polyethylene B; wherein polyethylene B1 has a density of at most 0.918 g/cm3, as measured according to ISO 1 183-2:2004 at a temperature of 23 °C; and a melt index MI2 of lower than the melt index MI2 of polyethylene A, as measured according to ISO 1133 Procedure B at a temperature of 190 °C and a load of 2.16 kg; and b2) at least 25% to at most 55% by weight of a metallocene-catalyzed polyethylene B2, wherein % by weight is based on the total weight of the metallocene-catalyzed polyethylene B; wherein polyethylene B2 has a density higher than the density of polyethylene B1, as measured according to ISO 1 183-2:2004 at a temperature of 23 °C; and wherein the melt index MI2 of polyethylene B2 is higher than the melt index MI2 of polyethylene B1, as measured according to ISO 1 133 Procedure B at a temperature of 190 °C and a load of 2.16 kg.
