Liquid containes made from certain ethylene copolymers have been found to leak less, swell and wrap less than conventional plastic liquid containes. The invention therefore provides the use of an ethylene and at least one C.sub.3-10 .alpha.-olefin copolymer having the following properties: i) MFR.sub.2=2 10; ii) MFR.sub.21/MFR.sub.2=15 20; iii) density --925 950 g/cm.sup.3; iv) molecular weight distribution Mw/MN=2.1 3.5 in the manufacture of a liquid container.
