Microporous film products permeable to moisture vapor and which act as barriers to liquid are made by a high speed method. Such microporous products are made at speeds in the order of above 500 fpm to about 1200 fpm. Thermoplastic polymers are melt blended to contain about 35 % to about 45 % by weight of a linear low density polyethylene, about 3 % to about 10 % by weight of a low density polyethylene; about 40 % to about 55 % by weight calcium carbonate filler particles, and about 2 % to about 6 % by weight of a triblock polymer of styrene.

L'invention concerne des films microporeux, perméables à la vapeur hume, faisant office de moyens d'arrêt aux liquides, et fabriqués par un procédé rapide. De tels produits microporeux sont fabriqués à des vitesses de l'ordre de plus de 500 pieds/minute à environ 1200 pieds/minute. Les polymères thermoplastiques sont mélangés à l'état fondu pour renfermer de 35 % environ à 45 % environ en poids d'un polyéthylène linéaire basse densité, de 3 % environ à 10 % environ en poids d'un polyéthylène basse densité ; de 40 % environ à 55 % environ en poids de particules de charge constituées de carbonate de calcium, et de 2 % environ à 6 % environ en poids d'un polymère tri-séquencé de styrène.
