Abstract
An apparatus and method are provided for forming a package with heat tack seals for a slice of a food item. A web of thermoplastic material is first formed into a tubular arrangement with a longitudinal heat tack seal. To form the tubular arrangement, means are provided for folding a continuous web of thermoplastic material into a tube and for continuously forming a heat seal along the longitudinal face of the folded web. The food item which has been formed into a soft mass, is then inserted into the tubular member and the tubular member is flattened to form a thin film tube. Means are provided for forming a heat tack cross-seal which is disposed substantially transverse to the longitudinal forward moving direction of the web.
