Abstract: A method for producing open-ended biaxially oriented containers includes forming a biaxially oriented intermediate by blow forming, without plug assist, a sheet of unoriented thermoplastic material into a forming tube to a depth of draw sufficient for full orientation of the side walls. The blow formed intermediate is placed on a male form a predetermined size, shape, and texture. The intermediate is heated above the orientation temperature of the thermoplastic material to heat shrink the intermediate onto the surface of the male form. The formed container is then removed from the male form.

Abstract: A method for producing open-ended biaxially oriented containers includes forming a biaxially oriented intermediate by blow forming, without plug assist, a sheet of unoriented thermoplastic material into a forming tube to a depth of draw sufficient for full orientation of the side walls. During blow forming the thermoplastic material is prevented from sticking to the side walls of the forming tube. The blow formed intermediate is placed on a male form a predetermined size, shape and texture. The intermediate is heated above the orientation temperature of the thermoplastic material to heat shrink the intermediate onto the surface of the male form. The formed container is then removed from the male form.

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.
