A plastic container has a high resistance to chemical attack and is made by a method including extruding and inflating a tube in a single operation by a coextrusion blow molding process to form a hollow plastic body. The tube consists of an outer layer made of glycol-modified polyethylene terephthalate (PETG) and an inner layer made of polyethylene terephthalate (PET), polyethylene naphthalate (PEN) or a mixture thereof. Selection of the foregoing materials and layers allows the plastic body for the container to be made in a single operation by coextrusion blow molding.
