Polymer blends for radio-frequency sealable objects, masterbatch for these blends and objects made thereof.

摘要

Polymeric compositions including 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. The invention also relates to the masterbatch employed 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 usable especially in the paper industry.
