INJECTION STRETCH BLOW BOTTLE

摘要

PROBLEM TO BE SOLVED: To provide an injection stretch blow bottle made from a polypropylene resin composition which has a desired transparency for a comparatively thick wall.

SOLUTION: The injection stretch blow bottle consists of the polypropylene resin composition and has a wall thickness of 0.85-1.6 mm at its trunk section, a ratio of haze value to the wall thickness (hereafter called a normalized haze value) of less than 5.0 %/mm at the trunk section and the haze value of 6.0% or less; wherein the resin component of the polypropylene resin composition is an isotactic polypropylene and/or a propylene-olefin copolymer.
