<p>The invention provides a method for making a medical bag which is capable of preventing the pattern printed upon the medical bag from separating and a medical bag made via the method. The method comprises the follow steps: preparing the sheets (21); carrying out corona discharge treatment over part of the surface of the sheets (21) for printing; carrying out printing upon the part having received corona discharge treatment with ultraviolet curing printing ink; irradiating the printed ink with ultraviolet rays to solidify the ink; cutting the sheets (21) according to each bag body segment; welding a discharge opening upon the bag body obtained via cutting; filling fluid respectively in a first space and a second space; and the main component for the sheets (21) is the polypropylene resin. The Young modulus ranges from 100 to 250 MPa, with the water contact angle ranging from 70 to 90 degrees.</p> |
