ABSTRACT:
A process for the manufacture of packages made of prefabricated containers which are substantially dimensionally stable and have at a filling end an outwardly projecting flange edge on which a cover sheet is fixed by welding, hot sealing or bonding. The process comprises the steps of providing a service belt consisting of a thermoplastic sheet material produced in a continuous sheet forming process. The continuous service belt moves along a path through a package forming, filling and closing work station. Recesses are formed in the service belt for receiving the prefabricated containers which are incorporated in succession and in a close spaced relationship into the recesses of the service belt. The prefabricated containers are filled with material and a continuous sheet web including weakening lines defining the outer edge surface dimension of a cover is supplied for each of the containers disposed in the recesses. The sheet web is applied to the containers to register a cover with each of the containers with the covers being separated along the weakening lines to form closed, filled containers. The remaining thermoplastic sheet material in the service belt is removed as waste after the covers have been separated therefrom thereby using the service belt only once as a disposable service belt to form the packages of the process.
