Abstract

Injection stretch blow molded containers are obtainable from olefin polymers, comprising homopolymers of propylene or copolymers of propylene with other C2-C10-alk-1-enes, which are obtainable by polymerizing the corresponding monomers with metallocene catalysts.Processes for producing injection stretch blow molded containers from olefin polymers, and also the use of olefin polymers for producing injection stretch blow molded containers, are described.
