<p>PURPOSE:To maintain the resilience of the bag for medical treatment liquid and to improve the blocking resistance and transparency thereof by using specific branched low-density polyethylene(LDPE) for an inner layer and using specific straight chain polyethylene(PE) for an intermediate layer and outer layer, respectively. CONSTITUTION:The branched LDPE of >=0.918g/cm<3> density obtd. by a high- pressure method is used for the inner layer and the straight chain LDPE which is a copolymer of ethylene and 1-olefin of <=0.915g/cm<3> density is used for the intermediate layer and the straight chain LDPE of >=0.920g/cm<3> density is used for the outer layer to form a laminate. The bag for medical treatment liquid having the excellent resilience, transparency, heat resistance, blocking resistance and mechanical strength is obtd. in this way. The practicable performance of the bag for medical treatment liquid is, therefore, additionally improved.</p> |
