PROBLEM TO BE SOLVED: To lessen the elution of low-mol.wt. components into an inside soln. by laminating sealant layers laminated with two kinds of mixed film layers formed by mixing high-density polyethylene(HDPE) and linear low-density polyethylene(LLDPE) respectively having specific densities by interposing adhesive resin layers on transparent film layers. SOLUTION: This plastic film for a medical treating liquid container consists of the sealant layers 2, 3 formed by respectively laminating the first, second film layers 2a, 2b and first, second film layers 3a, 3b which are formed by mixing the HDPE having the high density of >=0.941g/cm<3> in density and the LLDPE having 0.900 to 0.940g/cm<3> in density and vary in the mixing ratios thereof and the transparent film layers 5 which are laminated via the respective adhesive resin layers 4, 4 between these layers 2 and 3. At this time, the HDPE/ LLDPE (weight) is adequate 10/0 to 8/2 with the first film layers 2a, 3a and 5/5 to 1/9 with the second film layers 2b, 3b. |
