A heterogeneous apertured film wrapping element for an absorbent article is disclosed. The fluid-impervious plastic material that forms the apertured film has a continuous phase of a thermoplastic polymeric component and an immiscible, dispersed phase of a thermoplastic polymeric component having a lower melting point. The wrapping element is useful in applications involving heat sealing and similar thermal processes in absorbent articles, such as sanitary napkins, diapers, bandages, tampons, and the like.
L'invention concerne un élément d'enrobage constitué d'un film ouvert hétérogène destiné à un article absorbant. Le matériau plastique étanche aux fluides qui forme le film ouvert possède une phase continue d'un composant polymère thermoplastique et une phase dispersée, immiscible, d'un composant polymère thermoplastique possédant un point de fusion inférieur. L'élément d'enrobage est utile dans des applications mettant en oeuvre un thermoscellage et des procédés thermiques semblables concernant des articles absorbants, tels que des serviettes périodiques, des couches, des bandages, des tampons et analogues.
