Preform for the blow-molding of a container comprising a neck section (10), an adjoining wall section (20) having a substantially cylindrical shape, with in between a neck ring (12) as a transition region, and further a bottom section (30) which forms the base of the preform, which is composed of a multilayer structure consisting in two surface layers, the one of which (1) is directed outwardly respective the preform and wherein the other (3) is directed inwardly with respect thereto, with in between an intermediate layer (2) which forms a core layer, wherein both surface layers (1, 3) are composed of a primary material and wherein said intermediate layer (2) is composed of a secondary material, remarkable in that the center surface of said intermediate layer (2) is directed outwardly, toward the outer surface, with respect to the center surface of said wall section (20) and in that said primary and secondary materials respectively are mutually different. This invention further relates to a method for producing the aforementioned preform. Microorganismus are mixed into the polymers to improve material properties.

La présente invention a trait à une préforme pour le moulage par soufflage d'un récipient comportant une section de col (10), une section de paroi adjacente (20) ayant une forme sensiblement cylindrique, avec en interposition un anneau de col (12) comme zone de transition, et également une section inférieure (30) qui constitue la base de la préforme, qui est formée d'une structure multicouche en deux couches superficielles, dont l'une (1) est orientée vers l'extérieur par rapport à la préforme, avec en interposition une couche intermédiaire (2) qui forme une couche centrale, les deux couches superficielles (1, 3) étant réalisées en un matériau primaire et ladite couche intermédiaire (2) étant réalisée en un matériau secondaire. L'invention se caractérise en ce que la surface centrale de ladite couche intermédiaire (2) est orientée vers l'extérieur, vers la surface extérieure, par rapport à la surface centrale de ladite section de paroi (20) et en ce que lesdits matériaux primaire et secondaire respectivement sont différents l'un de l'autre. L'invention a également trait à un procédé pour la production d'une telle préforme.
