Abstract

Automatic packaging apparatus and methods for packaging food products such as bacon in evacuated or gas-filled packages. The disclosed machine is capable of convexly thermoforming two webs of packaging material into respective sets of pockets which are brought together in opposed positions to enclose the product. One preferred package made by the disclosed techniques comprises a transparent semi-rigid cup-like shell and a back-formed flexible film sealed over the shell opening. In operation of the disclosed machine, the product is loaded into the semi-rigid package shell from below, so that the upper sides of the product as introduced into the machine are pressed up against the inside surface of the shell, and after evacuation are held in that position by atmospheric pressure acting through the flexible film beneath the product. Thus, such upper sides of the product are visible through the transparent shell which serves as the display side of the package.
