Patent

CA 2383051

The present invention relates to a cold-drawn breathable film formed from a blend of a soft polymer component and a hard polymer component. The soft polymer component (SPC) is a copolymer of a major olefinic monomer and a minor olefinic monomer. The major olefinic monomer is either ethylene or propylene and forms the majority of the SPC. Preferred films after cold-drawing exhibit a water vapor transmission rate (WVTR) of at least 100 g-mil/m2-day.

L'invention concerne un film perméable à l'air étiré à froid, réalisé à partir d'un mélange de composant polymère mou et de composant polymère dur. Le composant mou est un copolymère de monomère oléfinique majeur et de monomère oléfinique mineur. Le monomère majeur est éthylène ou propylène, constituant la plus grande partie du composant mou. De préférence, ce film présente une transmission de la vapeur d'eau au moins égale à 100 g-mil/m?2¿/jour, après l'étirage à froid.
