Use of compositions based on ethylen polymers for the production of film. The compositions comprise an essentially linear ethylene polymer which has a density not exceeding 935 kg/m<3> and a molecular weight distribution not exceeding 18. The ethylene polymer contains a small number of short aliphatic branches from alpha-olefins having not more than 14 carbon atoms. The compositions comprise certain phosphorous compounds, phosphites, phosphonites or phosohonic acid derivatives, in an amount of at least 0.005 per cent by weight, based on the ethylene polymer. Films produced from the compositions have very satisfactory optical properties. |
