Abstract

La présente invention consiste en un procédé et une composition pour obtenir des pellicules d'un polymère thermoplastique, de préférence du polyéthylène, non respirantes et fortement chargées en particules minérales traitées de sorte que soient formés des espaces creux dans la structure, d'où une importante réduction de densité. étant donné que ces particules présentent une stabilité améliorée aux tensions subies pendant leur traitement dans les machines de confection de couches-culottes, et que, en outre, elles permettent une économie importante en termes de coûts du fait de leur haute teneur en charges minérales et de leur faible densité, elles s'avèrent spécialement appropriées pour une utilisation comme revêtement extérieur de couches-culottes et de compresses jetables.
