A thermoform packaging machine comprising, as work stations, a forming station for thermoforming troughs in a packaging film, at least one sealing station for sealing the troughs with a cover film, and a cutting station as well as a feeding device for causing a feed of the packaging film. A method for using such a thermoform packaging machine wherein a controller determines for two or more work stations, prior to a process step, which required feed length each of these work stations has, the required feed length indicating the distance by which the packaging film will have to be conveyed for the next process step of the respective work station, before a feed length specification is ascertained from the required feed lengths determined and the feeding device is controlled accordingly.

A method of forming dual layer water soluble packets includes drawing a base film into a cavity of a mold, drawing air through openings in the base film, metering an amount of a first product of a first color onto the base film in the cavity, metering an amount of a second product of a second color onto the amount of the first product, and, sealing a lid film to the base film.

Forming and sealing tool assemblies, utilized in conjunction with the commercially available, horizontal, form, fill and seal packaging machines, manually interchangeable with other forming and sealing tools assemblies, modifiable to accommodate the varying product shapes and sizes. 1. The forming tool assembly, designed to form the bottom portion of the package, is sub-divided into two sub-assemblies, the top and the bottom. a. The top sub-assembly, comprises of a forming chamber, and a forming heater. The bottom sub-assembly, releasably attached to a forming base containing a nozzle directing the vacuum and vent cycles, comprises of a forming o-ring tool base, a forming tool and a plurality of forming tool inserts. b. When utilizing the forming tool assembly, the packaging machine feeds into the forming station the first layer of the packaging film, where said packaging film is engaged by the top and the bottom sub-assemblies of the forming tool assembly, wherein i. the top sub-assembly projects the heat onto the packaging film, positioned directly above the forming pockets of the forming tool, and ii. the bottom sub-assembly, using the vacuum and vent cycles traveling from the vacuum system, through the forming base nozzle, through the air dispersing pocket shapes of the forming o-ring tool base, through the forming pockets of the forming tool, into the small air holes of the forming tool inserts, pulling the packaging film up against the bottom and side panels of said forming inserts, causing the packaging film to retain the shape of said forming tool inserts, thus pre-forming the bottom portion of the package. 2. The sealing tool assembly, designed to form the top portion of the package, is sub-divided into two sub-assemblies, the top and the bottom. a. The top sub-assembly, comprises of a sealing chamber, and a sealing heater. The bottom sub-assembly, releasably attached to a sealing base containing a nozzle directing the vacuum and vent cycles, comprises of a sealing o-ring tool base, a sealing tool with squeeze stoppers, and a sealing gasket. b. When utilizing the sealing tool assembly, the packaging machine using the conveying chain, transfers the pre-formed, and filled with product, bottom portion of the package, into the sealing station. Here, the machine feeds the second layer of the packaging film, and engages the top and the bottom sub-assemblies of the sealing tool assembly, wherein i. the top sub-assembly, while generating the heat, is lowered and sandwiches together, the first layer (forming the bottom of the package) and the second layer (forming the top portion of the package) of the packaging film, against the seal gasket protected by t

A package includes a chamber portion, a hollow frame adjacent to the chamber portion, and a frangible chamber closure zone between the chamber portion and the frame. A method of releasing at least one agent into a chamber portion of a package includes rupturing a frangible closure between the chamber portion and a hollow frame to release the at least one agent contained in the hollow frame into the chamber portion. A process of packaging includes providing a base web; placing a product on the base web; positioning over the product a lid web; fixing the lid web to the base web to form a chamber portion enclosing the product; fixing the lid web to the base web to form a hollow frame adjacent to the chamber portion; and including an agent in the frame.

The present invention relates to a thermoform packaging machine with a forming station. The forming station can include a forming tool lower part with at least one mold insert that is movable relative to the forming tool lower part. The present invention also relates to a method of forming a film including the step of moving the mold insert, relative to the forming tool lower part and the formed film, to a removal position while the film is clamped between the forming tool upper part and the forming tool lower part.

The present invention relates to a flow wrapper which comprises a form and/or film tube, which forms the planar film into a film tube and/or fills the film tube with a packaging item and which comprises means to provide a longitudinal- and/or cross-seal to the film tube.

The disclosure refers to a packaging device for manufacturing a packaging for a foodstuff. In particular, the packaging may include a trough-shaped lower packaging part and a top film which can be sealed together along their edges by means of a sealing tool of the packaging device. In order to improve a packaging device completely without evacuation or by evacuation in a simple and inexpensive manner with only a slight negative pressure in such a way that sufficient vapor purging is possible and at the same time cooling of the foodstuff before sealing or excessive degassing of the foodstuff does not take place, vapor can be introduced under pressure between the lower packaging part and the top film at at least one vapor entry point before sealing and can be released into the surrounding atmosphere at an outlet point from the packaging.

A thermoforming packaging machine with a top film forming station, wherein the forming tool upper part and the foaming tool lower part of the top film forming station are disposed above a transportation plane of a lower film. One of the forming tool upper part or the forming tool lower part are operably connected to a lifting mechanism by a traverse system. The lifting mechanism is disposed below the transportation plane of the lower film. The traverse system transfers a lifting force from the lifting device to one of the forming tool upper part or lower part through the transportation plane of the lower film.

A machine including a first film dispenser which dispenses a first film, a second film dispenser which dispenses a second film, a first form system configured to form a first shape in the first film, a second form system configured to form a second shape in the second film, and a seal system configured to join the first film to the second film after the first shape is formed in the first film and the second shape is formed in the second film, wherein the first form system includes a bucket configured to hold a forming plate and a form head configured to form a cavity between the form head and the bucket that receives the first film.

A method of forming dual layer water soluble packets includes drawing a base film into a cavity of a mold, drawing air through openings in the base film, metering an amount of a first product of a first color onto the base film in the cavity, metering an amount of a second product of a second color onto the amount of the first product, and, scaling a lid film to the base film.
