The present invention relates to a bag for storing bulk goods, wherein the bag comprises a multi-layer film comprising: (a) a first outer layer (c) a core layer; and (e) a second outer layer wherein the layers (a), (c) and (e) are positioned vis-à-vis each other in this order; wherein the multi-layer film comprises: •≥50.0 wt %, preferably ≥50.0 and ≤80.0 wt %, with regard to the total weight of the multi-layer film, of a polymer (A) comprising moieties derived from ethylene and moieties derived from 1-hexene, wherein the polymer (A) has: (i) a density of ≥910 and ≤930 kg/m3 as determined in accordance with ASTM D792 (2008); (ii) a melt mass-flow rate of ≥0.5 and ≤5.0 g/10 min, as determined in accordance with ASTM D1238 (2013) at a temperature of 190° C. under a load of 2.16 kg; (iii) a fraction that is eluted in analytical temperature rising elution fractionation (a-TREF) at a temperature≤30.0° C. of ≤6.0 wt %, with regard to the total weight of the polymer; and (iv) a fraction eluted in a-TREF at a temperature>94.0° C. of ≥20.0 wt %, with regard to the total weight of the polymer; and •≥20.0 and ≤50.0 wt %, preferably ≥20.0 and ≤40.0 wt %, with regard to the total weight of the multi-layer film, of a polymer (B) comprising moieties derived from ethylene and moieties derived from 1-butene, 1-hexene, or 1-octene, preferably ≥0.5 and ≤5.0 wt % of moieties derived from 1-butene, 1-hexene, or 1-octene, wherein the polymer (B) has: (v) a density of ≥945 and ≤965 kg/m3 as determined in accordance with ASTM D792 (2008); (vi) a melt mass-flow rate of ≥0.01 and ≤1.00, preferably ≥0.01 and ≤0.50, preferably ≥0.01 and ≤0.10 g/10 min, as determined in accordance with ASTM D1238 (2013) at a temperature of 190° C. under a load of 2.16 kg; and 19POLY0091-WO-PCT 19 Classification: General Business Use (vii) a melt mass-flow rate of ≥5.0 and ≤50.0, preferably ≥5.0 and ≤25.0 g/10 min, as determined in accordance with ASTM D1238 (2013) at a temperature of 190° C. under a load of 21.6 kg. [0044] Such bag may be manufactured via blow film extrusion at high speeds and high bubble stability, and such bag has a desirably high dart impact strength.

Bag for containing bulk goods

The present invention relates to a container liner for holding liquid goods, wherein the liner comprises a film comprising one or more layers, wherein at least one of said layers is a layer L1 comprising (a) ≥20.0 wt %, preferably ≥20.0 and ≤80.0 wt %, with regard to the total weight of that layer L1, of a polyethylene P1 having: •a density of >900 and <915 kg/m, preferably of >905 and <913 kg/mas determined in accordance with ASTM D1505 (2010); •a melt mass flow rate of ≥0.1 and ≤5.0 g/10 min, preferably of ≥0.5 and ≤2.0 g/10 min, as determined in accordance with ISO 1133-1 (2011) at 190° C. using a load of 2.16 kg; and (b) ≥20.0 wt %, preferably ≥20.0 and ≤80.0 wt %, with regard to the total weight of that layer L1, of a polyethylene plastomer P2 having: •a density of >880 and <905 kg/m, preferably of >890 and <904 kg/mas determined in accordance with ASTM D1505 (2010); •a melt mass flow rate of ≥0.1 and ≤5.0 g/10 min, preferably of ≥0.5 and ≤2.0 g/10 min, as determined in accordance with ISO 1133-1 (2011) at 190° C. using a load of 2.16 kg. Such container liner demonstrates a desirably high flex resistance, combined with a high dart impact resistance, and a high tensile strength.
