MULTILAYER PREFORM MADE OF SATURATED POLYESTER RESIN AND MULTILAYER BOTTLE FORMED FROM THE PREFORM

摘要

PROBLEM TO BE SOLVED: To provide a polyester preform excellent in transparency and surface slidability and a hollow molding.

SOLUTION: The multilayer preform made of a saturated polyester resin is formed from a saturated polyester resin layer having at least two layers including a skin layer and a core layer. The saturated polyester resin forming the skin layer contains inert particles with a mean particle size of 5μm or below. A multilayer saturated polyester resin bottle is obtained by extension-molding the preform.
