Title
(EN) MANUFACTURE OF SHAPED PRODUCTS OF BIAXIALLY ORIENTED POLYMERIC MATERIAL
(FR) FABRICATION DE PRODUITS FACONNES EN MATIERES POLYMERIQUES, A ORIENTATION BIAXIALE
Abstract
(EN)
Apparatus (80) and methods for they formation of biaxially oriented thermoplastic articles (70) having flat surfaces or sharp contours, along with the articles (70) themselves, are disclosed by the present invention. Such apparatus (80) and method relate to the heat-shrinking of biaxially oriented intermediates (50) onto male forms (82) to produce articles (70) of exacting dimensions and flat surfaces or sharply defined contours. Such thermoplastic articles (70) include autoclavable, hot fillable, heat stable, transparent PET containers.
