Disclosed herein is a film/nonwoven laminate which incorporates a low gauge machine direction oriented film layer laminated to a nonwoven support layer. The individual layers are designed such that the film layer, in the laminated state, has an elongation at break value in the cross machine direction that is greater the elongation at peak load value for the nonwoven layer in the same direction. Consequently, if the laminate is subjected to severe stretching forces in the cross machine direction, the nonwoven layer will fail before the film layer. In addition, the laminate preferably has a peak load value of at least 300 grams. As a result, the laminate is particularly useful as, for example, an outercover material for personal care absorbent articles or as a portion of an article of clothing, or as a portion of a surgical drape, or as a portion of a surgical gown.
L'invention porte sur un produit laminé associant un film à un non-tissé et comportant une couche constituée d'un film mince orienté dans le sens machine laminé avec un substrat de non-tissé. Les différentes couches sont conçues de manière à ce que le film une fois laminé présente une élongation au point de rupture perpendiculairement au sens machine supérieure à l'élongation de la couche de non-tissé sous charge maximale dans le même sens. Si donc le produit laminé est soumis à d'importantes forces d'étirement, perpendiculairement au sens machine, la couche de non-tissé cédera avant le film. La charge de rupture du produit laminé est d'au moins 300 grammes. Le produit laminé convient donc particulièrement comme revêtement extérieur d'articles absorbants d'hygiène corporelle.
