PACKAGING CONTAINER USING RECYCLED POLYESTER

摘要

PROBLEM TO BE SOLVED: To provide a polyester packaging container using a recycled polyester material wherein tendency toward crystallization occurring at the time of thermoforming is suppressed and the container is excellent in moldability and appearance characteristics such as transparency. SOLUTION: The packaging container comprises a thermoformed blended substance including thermoplastic polyester (A) which mainly contains ethylene terephthalate units with at least a part made of a recycled material and polyester or a polyester composition (B) induced from at least one of components selected among a group consisting of (a) dibasic acid mainly containing terephthalic acid, (b) a kind of diol mainly containing ethylene glycol and (c) ethylene oxide adduct of bisphenol, polyhydric alcohol of trivalent or higher and polyhydric carbonic acid of trivalent or higher.
