Abstract

Matériau d'emballage, article ou dispositif médical élaborés en vue de la stérilisation par rayonnement de lui-même, de son contenu, ou de l'un et l'autre, ou qui a été soumis à un rayonnement suffisant pour une telle stérilisation. Ce matériau consiste en un mélange d'environ 99 à 50 % en poids de polypropylène homo- ou copolymérisé, qui renferme environ 1 à 50 % en poids de polyéthylène produit par catalyse sur site unique. L'invention porte également sur un procédé de fabrication d'un tel matériau d'emballage, d'un tel article ou d'un tel dispositif médical résistant au rayonnement.
