Abstract

L'invention vise la fabrication de récipients (2) à ouverture étroite et corps allongé (tels que bouteilles ou analogues) en polypropylène par soufflage ou étirage­-soufflage ; on prévoit que la préforme (1) . en polypropylène supporte, au cours de l'étape de soufflage ou d'étirage-soufflage, un allongement longitudinal dans un rapport (L/1) compris entre environ 2 et 3,5 et un allongement radial (D/d) dans un rapport compris entre environ 2 et 3.
