Title
(EN) LOW MELT FLOW RESINS FOR MEDICAL APPLICATIONS IN INJECTION-STRETCH-BLOW-MOULDING
(FR) RÉSINES À BAS POINT DE FUSION POUR INJOCTIONTION SOUFFLAGE BIÉTIRAGE DANS DES APPLICATIONS MÉDICALES
Abstract
(EN)
The present invention discloses a method for preparing vials, preferably medical vials, by one-stage injection-stretch-blow-moulding with a random copolymer of propylene (RCP) having a melt index of from 1 to 3 dg/min, an ethylene content of less than 3.5 wt% with respect to the weight of the RCP and wherein the preform injection temperature is of at least 210 °C.
(FR)
L'invention porte sur un procédé de préparation de flacons, de préférence à usage médical par injection soufflage biétirage en une étape d'un copolymère aléatoire de propylène (RCP) présentant un indice rhéologique de 1 à 3 dg/min, et une teneur en éthylène de moins de 3,5 % du poids de RCP, la température d'injection de la préforme étant d'au moins 210°C.
