ABSTRACT:
A resin composition which is a suitable component of a container which is superior in oil resistance and not deformed or swelled, even by oily filled contents in preservations. Additionally, the container made of the resin composition is superior in flexibility, squeezing capability, pressing out capability, pinch off adhesion capability, and heat sealing capability. According to this invention, there is provided a blended resin composition comprising at least one kind of a first polyester resin selected from the group consisting of amorphous polyester resins and polyester resin having a peak area of not more than 20mJ/g, which has a glass-transition temperature not less than 50.degree. C. and at least one kind of a second polyester resin which has a glass-transition temperature not more than 40.degree. C. The first polyester resin has a first peak representing a temperature dependency of tan .delta.. The second polyester resin has a second peak representing said temperature dependency of tan .delta.. The first peak of the first polyester resin is located at a higher temperature than the second peak of the second polyester resin. The blended resin composition has a third peak and a fourth peak. The third and fourth peaks of the blended resin composition are located at a lower temperature than the first peak. The third and fourth peaks of the blended resin composition are located at a higher temperature than the second peak.
