Multi-layered, coinjection stretch-blow molded containers are obtained by stretch-blow molding a preform prepared by coinjection molding a polyester resin and an EVOH resin blend in which one of the EVOH resins is dispersed as particles in an EVOH resin matrix. Containers prepared with this EVOH blend have good impact delamination resistance, good gas-barrier properties, and high transparency is high, even without an adhesive layer. The EVOH blend is composed of two EVOH resins having different ethylene contents and degrees of saponification. The blend exhibits at least two crystal fusion peaks by DSC. |
