Articles having an exterior surface comprising an inorganic biocidal agent and a first thermoplastic resin can provide a good combination of biocidal activity and physical properties. The biocidal activity of an article or multi- layer article can be enhanced by texturizing the exterior surface of the article or multi-layer article. The surface can be texturized by calender with a textured roll, mechanical or chemical abrading, or molding in a textured mold. The biocidal activity may also be enhanced by thermoforming an article or multi-layered article into a shaped article having the desired level of biocidal activity.

L'invention porte sur des articles dont la surface extérieure comporte un agent biocide minéral et une première résine thermoplastique et présentant une bonne combinaison d'activité biocide et de propriétés physiques. L'activité biocide d'un article ou d'un article multicouche peut être renforcée en texturant sa surface extérieure. La surface peut être texturée: par calandrage au moyen d'un rouleau texturé, par abrasion mécanique ou chimique, ou par moulage dans un moule texturé. L'activité biocide peut également être renforcée par le thermoformage d'un article ou d'un article multicouche présentant le niveau désiré d'activité biocide.
