Abstract

A multi-layer polyester container comprising inner and outer layers of a polyester resin and at least one intermediate layer of a functional resin or a functional resin composition, wherein a difference of tan δ of the inner polyester layer at 80° C. and 60° C. is 0.035 or less in the measurement of the dynamic viscoelasticity (DMS) thereof at 0.5 Hz. Even when the functional resin or the functional resin composition having a large draw stress is used as an intermediate layer, therefore, excellent transparency is obtained while effectively exhibiting the function such as barrier property possessed by the functional resin or the functional resin composition.
