    Abstract: The invention is directed to bimodal polyethylene having a flow ratio FRR ranging between ≥30 and ≤40, a density ranging between ≥949.0 and ≤952.0 kg/m3, an MFR190/5 ranging between ≥0.1 and ≤0.2 g/10 min and comprising from 50 to 54% by weight of an ethylene homopolymer A and from 46-50% by weight of an ethylene-butene copolymer B, where all percentages are based on the total weight of the composition and wherein ethylene homopolymer A has a viscosity number ≥70 and ≤100 cm3/g and a density between ≥968 and ≤972 kg/m3. The polyethylene is suitable to be applied in the production of pipes.

    Abstract: The present invention relates to a film comprising at least one sealing layer wherein at least one layer A of the sealing layer(s) comprises a polyethylene comprising moieties derived from ethylene and moieties derived from an α-olefin comprising 4 to 10 carbon atoms, the polyethylene having a density of ≥870 and ≤920 kg/m3 as determined in accordance with ASTM D792 (2013), wherein the polyethylene has: x a fraction of material that is eluted in analytical temperature rising elution fractionation (a-TREF) at a temperature ≤30.0° C. of ≥5.0 wt %, preferably ≥10.0 wt %, with regard to the total weight of the polyethylene; x a shear storage modulus G′ determined at a shear loss modulus G″=5000 Pa of >700 Pa, G′ and G″ being determined in accordance with ISO 6721-10 (2015) at 190° C.; x a melt mass-flow rate, determined at 190° C. under a load of 2.16 kg in accordance with ASTM D1238 (2013) of ≥2.60 and ≤4.90 g/10 min; and x a chemical composition distribution broadness (CCDB) of ≥15.0, preferably ≥20.0. Such film allows for sealing of the film at a reduced temperature, whilst still providing a desirable seal strength, and a desirable hot-tack strength.
