<p>PURPOSE:To maintain the resilience of the bag for medical treatment liquid and to improve the blocking resistance and transparency thereof by using the compd. of a proper ratio of specific branched low-density polyethylene(LDPE) for an inner layer and outer layer and using specific straight chain LDPE for an intermediate layer. CONSTITUTION:The compsn. consisting of 70 to 95wt.% straight chain LDPE which is a copolymer of ethylene and 1-olefin of >=0.920g/cm<3> density and 5 to 30wt.% branched LDPE of >=0.918g/cm<3> density obtd. by a high-pressure method is used for the inner layer and the outer layer and the straight chain LDPE of <=0.915g/cm<3> density is used for the intermediate layer. These layers are laminated. The bag having the resilience and mechanical strength and the excellent blocking resistance and transparency is obtd. in this way and, therefore, the practicable performance of the bag for medical treatment liquid is additionally improved.</p> |
