<p>PURPOSE:To protect a content medicinal fluid against light, and visually observe the state of the liquid by forming a shading soft vessel for the fluid out of a soft plastic sheet having a specific value of underwater transmission factor in a specific wavelength zone as well as in specific wavelength. CONSTITUTION:A shading soft vessel for a medical fluid is formed out of a soft plastic sheet having underwater transmission factor equal to or less than 10% in a wavelength zone between 290 and 420nm, and 60% or more in 600nm wavelength. In this case, the base material of the sheet is preferably made, for example, of linear low density polyethylene (LLDPE) having density between 0.908 and 0.920g/cm<3>, ethylene vinyl acetate copolymer (EVA) containing 5 to 30wt.% of vinyl acetate, or the copolymerized composition of crystalline polypropylene or crystalline copolymer (PP) mainly composed thereof, and atactic amorphous polypropylene or a copolymer mainly composed thereof.</p> |
