FIELD: medicine.
SUBSTANCE: group of inventions relates to injection fluid bags. Injection fluid bag comprises: an innermost layer and an outermost layer of a polypropylene-based resin; intermediate layer; and two adhesive layers on both sides of the intermediate layer. Intermediate layer comprises a mixture of 60 to 90 % by weight of a crystalline polyamide resin and 10 to 40 % by weight of a non-crystalline polyamide resin, wherein the crystalline polyamide resin has a combined monomer and low molecular weight polymer content of 0.8 % by weight or less, the non-crystalline polyamide resin comprises a semi-aromatic polyamide. Injection fluid bag has a maximum optical density in the UV range of 0.08 or less, measured at a wavelength of 220 to 240 nm. Also disclosed is a kit for administering a drug, comprising an injection solution package and a drug solution.
EFFECT: group of inventions provides practical impermeability characteristics and satisfies the maximum optical density standard.
