Abstract
An apparatus and method for continuously forming hermetically sealed packages of a food item. A continuous web of thermoplastic material is folded and continuously formed with a hermetic longitudinal seal. The food item is inserted between inner surfaces of the tubular web member, which is then flattened to form a thin slice. A hermetic cross-seal is continuously formed transverse to the longitudinal seal. The web can be cooled before the cross-seals are formed.
