(57) [Abstract] [Problem] To prevent deterioration of a medical solution due to oxygen, prevent volumetric expansion, improve hygiene and flexibility, improve transparency, To provide a medical solution bag made of a laminated film which is excellent in heat resistance, pinhole resistance, etc. and is easy to dispose. SOLUTION: This is a medical solution bag made of a laminated film, wherein the laminated film has an innermost layer composed of a polyolefin layer and an adhesive layer, a polyamide layer, an adhesive layer, and a polyolefin layer in order from the innermost layer to the outer layer. At least 5 The laminated film is characterized in that the polyamide layer is composed of a polyamide having a low molecular weight polymer content of 0.7% by weight or less and an ash content of 500 ppm or less. [Effect] The above problem is solved. |
