Abstract
Abstract A hollow blow-moulded container (1) of a biaxially oriented polyethylene terephthalate or saturated polyester resin in which the neck section (2) is crystallized, and the body (3) is coloured transparently or opaquely and is thermoset. Thus, the container (1) affords better protection to its contents from the effects of external light, and the neck section (2) can be rigidly formed with stable physical properties.
