A pharmaceutical product comprising an infusion bag containing a medical liquid, wherein the infusion bag comprises a multilayer film comprising:
- an inner layer;
- an outer layer comprising a styrene-ethylene/butylene-styrene block copolymer in a matrix of a polymer;
- and
- an intermediate layer disposed between the inner layer and the outer layer, the intermediate layer comprising a styrene-ethylene/butylene-styrene block copolymer in a matrix of a polymer,
- wherein a ratio, by weight, of styrene to ethylene and butylene of the outer layer is between 0.18 and 0.28, and
- wherein a ratio, by weight, of styrene to ethylene and butylene of the intermediate layer is between 0.10 and 0.16.
A pharmaceutical product comprising a medical liquid contained within an infusion bag, wherein the infusion bag comprises a multilayer film comprising:
- an inner layer, an outer layer, and an intermediate layer disposed between the inner layer and the outer layer, wherein each of the inner layer, the outer layer, and the intermediate layer comprises a styrene-ethylene/butylene-styrene block copolymer in a matrix of a polymer,
- wherein a ratio, by weight, of styrene to ethylene and butylene of the inner layer and the outer layer is between 0.18 and 0.28,
- wherein a ratio, by weight, of styrene to ethylene and butylene of the intermediate layer is between 0.10 and 0.16, and
- wherein the polymer of the inner layer and the intermediate layer is a polypropylene random copolymer and the polymer of the outer layer is a polypropylene homopolymer.
