Document Type and Number:
WIPO Patent Application WO/2011/118608
Kind Code:
A1
Abstract:
Disclosed is a heat-resistant stretch molded container which has excellent transparency and stretch balance and is obtained without undergoing a heat fixation process.
Specifically disclosed is a stretch molded container comprising a layer that is formed from an ethylene terephthalate polyester resin. The stretch molded container is characterized in that: the layer is formed from a mixture of (A) an ethylene terephthalate polyester resin and (B) a chain extender that has a functional group reactive with a terminal functional group of the polyester resin (A); the chain extender (B) is contained in an amount of 10-4,000 ppm relative to the ethylene terephthalate polyester resin (A); and at least the body portion of the container has a tan δ peak of 0.3 or less as determined by dynamic viscoelasticity measurement.
