Abstract
A polyester container made from a polymer having ethylene glycol moieties, isosorbide moieties and terepthaloyl moieties, and the method of making the container is described. The polyester container is suitable for holding liquids and solids, and may be hot-filled or cold-filled. In particular, wide-mouth jars and narrow-necked bottles may be formed. The polyester has an inherent viscosity of at least 0.35 dL/g when measured as a 1% (weight/volume) solution of the polyester in o-chlorophenol at a temperature of 25.degree. C.
