The present invention relates to thermoplastic compositions for making a liquid impermeable moisture vapour permeable layer by coating the composition onto a substrate. The thermoplastic compositions comprise preferred thermoplastic polymers and suitable plasticisers to adjust the viscosity of the composition at the process conditions. The layers made from the thermoplastic compositions of the present invention can find a variety of applications wherein moisture vapour permeability is desirable, such as within absorbent articles for example diapers, sanitary napkins, panty liners and incontinence products, and also protective bedding covers, protective clothing and the like.
