A method for packaging a good by means of a package formed of a shrinkable lower filmand an upper filmis provided. The lower film may be deep-drawn to form a container for accommodating the good, and after filling in the good, an upper film may be supplied for covering. The such-formed package is sealed and then may be subjected to shrinking in an evacuating and sealing station. Consecutively to the evacuating and sealing, an additional shrinking may be performed by subjecting the package to heat from all sides, so as to remove the film section having developed between the part of the lower and the upper film directly resting against the good and the sealing rim. A corresponding device for executing the method is indicated.

Method and device for packaging

A packaging machine is described. A plurality of working stations is arranged between the input side and output side of the machine. A conveyor moves packages carrying a product along a path from the input side to the output side through the working stations. A device feeds a cover film onto the packages. The cover film has two layers bonded together with a limited bonding strength. A first layer has a portion protruding beyond said second layer. Another device separates the first layer from the second layer in a defined region extending across the cover film transversely to the conveyor path. The separator seals the defined region of the cover film and supplies a pressurized fluid to said defined region. The defined region includes at least part of the protruding portion of the first layer. A method of using the packaging machine to package product also is described along with the package that is made.

Apparatus for separating laminated areas of multi-layered film, packaging machine comprising this apparatus and package having a cover film consisting of at least two laminated layers

A packaging machine comprises a base frame having an input side and an output side as well as a transport path from the input side to the output side. A plurality of tray carriers for holding trays are arranged in succession from the input side to the output side along the transport path. A drive means advances the tray carriers in an advancement plane. Further, feed means are provided for feeding a cover film for covering the filled trays. Successive tray carriers are pivotally interconnected by means of pivoting coupling links. Each tray carrier has engagement elements provided at its forward and rearward side. The drive means is formed as a drive chain with a chain strand trained over chain wheels and the engagement elements engage the chain strand when in a position adjacent thereto. The feed means for the cover film likewise includes laterally guided chain strands which are guided in a plane parallel to the first chain strand along a predetermined length parallel to the first chain strand and at a predetermined distance therefrom. The engagement elements engage the first chain strand along a predetermined length and also the second chain strand along a predetermined length whereby both drive chains are driven by the same drive means.
