ABSTRACT:
The present invention is directed to a method and apparatus for manufacturing a tray having an integral purge juice trap. A particularly important step in the method is adhering a border area of a perforated thermoplastic sheet to a raised shoulder area of a tray. Preferably, this step is accomplished simultaneously with the step of perforating the thermoplastic sheet. A preferred method for adhering the border area to the shoulder area is heat sealing.
