<p>PURPOSE:To provide a medical bag such as blood bag, chemical bag, and culture bag which can regulate the transmitted wavelength of ultraviolet ray and efficiently performing ultraviolet ray irradiation treatment. CONSTITUTION:In a medical bag, 0.01-1wt.% of at least one kind or more of additives selected from thermal stabilizer, ultraviolet ray absorber, and antioxidant is added to a polyolefin resin to regulate the bag to make the wavelength area less than 290nm of ultraviolet ray impermeable. Thus, at least UV-C is made perfectly impermeable, and these additives and the blending composition are properly regulated, whereby medical bags of UV-A permeable type and UV-B permeable type can be selected according to the purpose of use. Since UV-C giving a bad effect on cells can perfectly be shielded, irradiation times of UV-B and UV-A can be extended, and inactivation of leucocyte can be efficiently performed.</p> |
