Bag-in-Bag VF/F/S is Really Two Machines in One Enclosure

While both machines operate independently, and bag lengths, temperatures and speeds are independent of one another, they operate hand-in-glove with the top machine cutting off sealed bags into the top of the forming tube of the second machine.

Mark Stenske, Service Manager for Matrix, a ProMach company, used PACK EXPO Connects to demonstrate how the Matrix Bag-in-Bag provides an innovative way to fill single-serve and multiple-serve pillow bags in an overwrap or master bag.

The Matrix Elete Bag-in-Bag machine is essentially two machines in a single frame. In the demonstration, one bagger above was feeding into another below in a single enclosure. In a ground coffee application, the top section packages product into heat-sealed filter paper pouches, and the lower section bags those pouches in metalized film packs. Visible are both rolls of filter-paper film and foil film, one above the other, on the back of the machine. At the front, visible are pull belts advancing the upper filter paper as the vertical seal bar intermittently seals the top, and the end-seal jaws separate each filter-paper pouch, and drop them into a funnel to introduce to the second portion of the machine.

There, on the bottom section, again pull belts advance the film, this time the metalized plastic, with horizontal seals making the end seal and a knife separates each metalized film pouch. All programs are saved into recipes and can be recalled into future runs.

Another application demonstrated included small, single-serve candy bags in registered film being filled into clear plastic film at a ratio of 10:1, equating to 90 primary bags/minute and 9 secondary clear bags/minute.
