[PROBLEMS] To provide a medical bag containing medicine, blood, etc. that has high hygiene, excellent flexibility, transparency, glossiness and delamination strength, and good pinhole resistance and heat sealability. Is an issue. The first layer is a metallocene-catalyzed propylene / α-olefin random copolymer and propylene homopolymer, the second layer is a specific ethylene / α-olefin polymer and high-density polyethylene, and the third layer is It is a composition of a specific propylene / α-olefin random copolymer, and the melting peak temperature and melt viscosity of each layer are controlled to predetermined values. [Selection figure] None |
