Abstract: A film includes a sealing layer containing a polyethylene A having moieties derived from ethylene and moieties derived from an α-olefin comprising 4 to 10 carbon atoms, the polyethylene A having a density of ≥870 and ≤920 kg/m3, wherein the polyethylene A has: 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 % and ≤15.0 wt %, with regard to the total weight of the polyethylene; and two distinct peaks in the a-TREF curve in the elution temperature range of between 50.0 and 90.0° C., wherein the elution temperature gap between the two peaks is ≤17.5° C. The film can be sealed at a desirably low temperature, whilst still having a desirable seal strength. Furthermore, the film demonstrates a desirably high heat stability.
