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.
A method for filling and closing off a two-chamber container with different filling materials includes two sealing steps for the closing-off procedure, the first chamber being filled with the first material under sterile conditions and closed off over a first partial seal with a covering sheet, after which the second chamber is filled with the second material and closed off by means of a second partial seal with formation of a fully sealed two-chamber container.
A method for applying to a support multiple articles held in protective elements comprises the following steps: thermoforming a thin plastic material sheet to provide a plurality of hollow recesses therein, introducing into the recesses a plurality of articles, applying to the recesses a closure film, coupling to the closure film a multilayer strip including a first film element which can be bound to the closure film, an adhesive layer and a siliconized paper layer, the method further including a die-cutting step for die-cutting material portion encompassing the recesses and removing the waste material including all the mentioned layers, with the exception of the siliconized paper layer.
A process for making and packaging multi serving ice cream products using cryogenic hardening of ice cream in consumer containers before the containers are closed and labeled. A plastic tray container which is stable when disposed horizontally or vertically provides better processing and an improved package for both retailers and consumers.

A reusable package and method suitable for storage and handling of a fragile dicing blade includes a rigid card having a smooth surface upon which the blade is placed. A flexible plastic film is placed over the blade and card surface and bonds to the surface through a molecular bonding action with sufficient bonding force for holding the disk in place on the card. With such a combination of card, blade and film, the blade is protected during storing, shipping and handling. Further, such a packaging method provides for repeated use of this non-adhesive package thereby increasing useful life of both the blade and package. Molecular bonding of the film to the card surface provides sufficient strength to hold the blade and to provide a hermetically sealed chamber within which the blade is positioned and stored. A package and handling for a fragile dicing blade and electronic components is described but application for components having stringent handling and storage requirements is appropriate.
