<p>PROBLEM TO BE SOLVED: To provide a laminate having high sanitation properties and excellent flexibility and transparency and also good in heat resistance and pinhole resistance and a medical bag formed of the same. SOLUTION: A polypropylene resin is used in an outer layer and a polyethylenic resin material based on an ethylene/α-olefin (3-18C) copolymer containing low and high crystalline components wherein the peak temp. of the low crystalline component of a TREF elution curve is 45-85 deg.C, a ratio (H/M) of the peak height of the low crystalline component and the height (M) of the min. trough between the peak of the low crystalline component and that of the high crystalline component is 9 or more, the area ratio of the peak temp. of the low crystalline component or lower to the total area of the elution curve is 35% or more and an MFR is 0.1-20 g/10 min is used in an intermediate layer and the outer layer, the intermediate layer and an inner layer are laminated in this order to obtain a laminate and a medical bag is formed from this laminate.</p> |
