Title:
MULTILAYERED PLASTIC CONTAINER
Document Type and Number:
Japanese Patent JP2009248996
Kind Code:
A
Abstract:
To provide a multilayered plastic container with excellent balance in flexibility, rigidity and falling resistance.
The multilayered plastic container 1 includes a core layer 5 formed of a resin with gas barrier properties, and an inner layer 6 and an outer layer 7 formed of a polyolefin resin. The polyolefin resin of the inner layer 6 is an ethylene--olefin copolymer having a long-chain branch structure polymerized by using a metallocene catalyst. The ethylene--olefin copolymer has a melt tension of 4.5-12 g at 190C, a melt flow rate (MFR) of 1.0 g/10 minutes, a density of 0.921-0.936, and a tensile impact strength of 800 kJ/m2.
