BREATHABLE FILM

The invention relates to a breathable film. The specific ball-drop impact resistance of the film is more than 100 mm per gram polymer per square meter. The film has a water vapor permeability of at least 1000 g/m2 in 24 hours. The elongation at break of the film in the machine direction is less than...

Zusammenfassung:	The invention relates to a breathable film. The specific ball-drop impact resistance of the film is more than 100 mm per gram polymer per square meter. The film has a water vapor permeability of at least 1000 g/m2 in 24 hours. The elongation at break of the film in the machine direction is less than 200%. L'invention concerne une feuille respirante. La hauteur de chute spécifique d'impact de chute de balle de la feuille est supérieure à 100 mm par gramme de polymère par mètre carré. La feuille présente une perméabilité à la vapeur d'eau d'au moins 1000 g/m2 en 24 heures. L'allongement à la rupture de la feuille dans la direction de machine est inférieur à 200 %.`
