The chemical composition may contain, for instance, various additives, such as a polysiloxane softener and one or more beneficial agents.

La présente invention concerne un procédé qui permet l'application topique de compositions contenant un additif chimique sur une bande de papier. L'invention se rapporte également à des produits en papier formés selon le procédé précité. En général, le procédé consiste à extruder une composition contenant un additif chimique à travers une filière de fusion-soufflage et à appliquer ensuite la composition sur une bande de papier en mouvement. En particulier, le procédé de l'invention permet d'appliquer des compositions collantes sur une bande à travers une filière de fusion-soufflage sans boucher le bout de la filière. Dans un mode de réalisation, la composition chimique est extrudée dans des fibres et appliquée sur la bande de papier.
