Title:
複室容器
Document Type and Number:
Japanese Patent JP4412463
Kind Code:
B2
Abstract:
Multi-chamber container (1) having its interior partitioned by weak seal portions (3) provided through detachable heat sealing so that multiple contents are accommodated separately from each other, wherein use is made of heat seal layers consisting of a composition comprising two types of propylene copolymers components (component A and component B) from propylene and ethylene and/or a C 4 -C 8 ±-olefin which have the following elution properties. Thus, a region wherein a change of seal strength by a change of heat seal temperature is small has a wide temperature range to thereby facilitate controlling of the seal strength at the weak seal portions. The proportion (mass%) of, to total solution, elution according to the TREF method (temperature: 0 to 140°C and solvent: ODCB) is as follows. With respect to component A: 15 to 50 at 0°C, and 5 to less than 15 at 60 to 90°C. With respect to component B: 0 to 25 at 0°C, and 15 to 70 at 60 to 90° C.
