INJECTION BAG AND INJECTION PREPARATION ASSEMBLY

ABSTRACT An injection bag that is formed of a multilayer film comprises an innermost layer that is formed of a polypropylene-based resin; an outermost layer that is formed of a polypropylene-based resin; an intermediate layer that is situated between the innermost layer and the outermost layer; and two adhesive layers that are situated on either side of the intermediate layer, the intermediate layer including a mixture of 60 to 90 mass% of a crystalline polyamide resin and 10 to 40 mass% of a non-crystalline polyamide resin, the crystalline polyamide resin having a combined content of a monomer and a low-molecular-weight polymer of 0.8 mass% or less, the non-crystalline polyamide resin including a semi-aromatic polyamide, and the injection bag having a maximum ultraviolet (UV) absorbance measured in accordance with the Test Methods for Plastic Containers specified in the Japanese Pharmacopoeia 16th Edition of 0.08 or less. CA 2914314 2019-01-16 La présente invention concerne un sac de fluide pour injection obtenu à partir d'une pellicule laminée où la couche intermédiaire comprend un mélange de 60 % en masse à 90 % en masse d'une résine polyamide cristalline et 10 % en masse à 40 % en masse d'une résine polyamide non cristalline. Dans la résine polyamide cristalline, la teneur en monomères et polymères de faible masse moléculaire est de 0,8 % en masse ou moins. La résine polyamide non cristalline comprend un polyamide semi-aromatique.
