<p>PURPOSE:To provide satisfactory heat sealing properties by using a multilayer laminate consisting of a crystalline polypropylene layer A, a layer B containing a polymer composition of polypropylene amorphous polymer, and a low-density polyethylene layer C, which are positioned as an outermost layer, an intermediate layer and an innermost layer respectively. CONSTITUTION:A multilayer laminate is composed of a crystalline polypropylene copolymer layer A, a layer B containing a polymer composition of polypropylene or polybutene amorphous polymer, and a low-density polyethylene layer C as main components. In addition A, B, C are positioned as an outermost layer, an intermediate layer and an innermost layer respectively. Further, a base material for a medicare container is not only a multilayer laminate of three different kinds and three layers but also can be, for example, the form of a laminate composed of three different kinds and three layers type of A/B/A/C.</p> |
