MEDICAL MULTI-CHAMBER CONTAINER

摘要

PROBLEM TO BE SOLVED: To provide a multi-chamber container which can form an isolation part of a stable half-sealing strength without requiring neither a complicated material composition nor structure. SOLUTION: This medical multi-chamber container which has the periphery part thereof fully sealed and an isolation part thereof half-sealed employs a single layer film with a thickness of 50-300μm that comprises a propylene/α- olefin random copolymer with the content of propylene of 50 wt.% or more while the content ofα-olefin, which is at least one selected from those having the carbon number of 2-12, is 2-8 wt.% and the melt flow rate of the copolymer is 0.1-20 g/10 min. when measured on the conditions of a load of 2.16 kg at a temperature of 230 deg.C in conformity to JISK 7210. The half sealing is made under the conditions of 4-12% in the forcing rate at a sealing temperature of 122-127 deg.C by a heat seal bar driven by a servo motor.
