Abstract:
Apparatus and methods for the formation of biaxially oriented thermoplastic articles having flat surfaces or sharp contours, and the articles so produced. Such apparatus and methods relate to the heat-shrinking of biaxially oriented intermediates onto male forms to produce articles of exacting dimensions and flat surfaces or sharply defined contours. Such thermoplastic articles include autoclavable, heat fillable, heat stable, transparent PET containers.
