Abstract:
A breathable, heat-sealable composite film comprising first and second layers of polymeric material wherein (i) the polymeric material of the first layer comprises copolyester comprising monomeric units derived from one or more diol(s); one or more dicarboxylic acid(s); and one or more poly(alkylene oxide)glycol(s); and (ii) the second layer is a heat-sealable polymeric layer, and a process for the production thereof.
