ABSTRACT:
Methods for the formation of biaxially oriented thermoplastic articles having flat surfaces or sharp contours, along with the articles themselves. Such methods relate to blow forming a sheet of unoriented thermoplastic material to form biaxially oriented shaped intermediates, followed by the heat-shrinking of the biaxially oriented intermediates onto a male form to produce articles of exacting dimensions and flat surfaces or sharply defined contours. Such thermoplastic articles include autoclavable, hot fillable, heat stable, transparent PET containers.
