ABSTRACT:
The invention relates to polymeric compositions comprising at least one polyolefin, at least one thermoplastic starch and at least one ionic compound, the latter being present in a content such that the concentration of anions and of cations in the composition is from 0.002 to 5 mol/kg. It also relates to the master mixture used for the manufacture of these compositions and containing the thermoplastic starch and the ionic compound. The compositions are suitable, in particular, for the production of mono- or multilayer films which can be used, especially, in the paper-making industry.
