Abstract

The present invention relates to shape-formed, three dimensional, moisture vapour permeable, liquid impermeable articles comprising moisture vapour permeable, liquid impermeable structures comprising a thermoplastic composition having a higher processability. The thermoplastic compositions comprise preferred thermoplastic polymers and suitable plasticisers to adjust the viscosity of the composition at the process conditions. The shape-formed three dimensional articles of the present invention can find a variety of applications wherein moisture vapour permeability combined with liquid imperviousness are desirable.
