A vertical packaging machine originally created for confectionery packaging has been redesigned for use with a wider selection of foods requiring modified atmosphere packaging (MAP) applications, its manufacturer claims.
PFM Packaging Machinery says that its PFM Comet machine is ideal for high-speed form fill and seal wrapping using heat sealable film for products like cheese and nuts that require gas flushing in compact spaces.
MAP is used extensively in the food industry as a means of extending shelf life.
Typically, air is removed from the space above the food as it is being packed by flushing the package with an inert gas such as carbon dioxide or nitrogen.
It is an increasingly lucrative technology for packaging companies currently used to provide fresher food such as sandwiches, fresh pizzas and meats.
According to PFM, the Comet has been redesigned from its earlier PV260 packaging system to offer manufacturers a more compact packaging technology that also ensures improved control and synchronization with product feeding and dosing systems.
PFM department manager, Ermanno Roso, said the machine had allowed the group to improve upon the previous design, originally used for wrapping jelly sweets, with further development allowing for the extension of its applications.
"The system was supplied complete with an MBP multi-head weigher and currently has a production speed of 140 packs per minute which is impressive given that the features of the company's product are soft, sticky and extremely lightweight," he stated.
According to PFM, the design of their new machine makes use of a stainless steel frame, which it claims offers food manufacturers robust protection from organism infiltration as well as a more user-friendly cleaning system.
The PFM Comet also contains the latest generation Long Dwell rotary sealing system, which the company claims has been found in testing to achieve 200 mechanical cycles a minute while also ensuring hermetic sealing.
The manufacturer says that the addition of this technology to the machine has allowed additional packaging capabilities such as for products like mozzarella in brine, due to the low leakage rate of the packs.
The machine's capabilities for high speed 100 per cent hermetic sealing reduces any possible negative effect if the product falls against closed sealing jaws or the seal itself, according to the company.
The machine also makes use of an LCD colour touch screen to control the operations. The screen can also be connected remotely for servicing and repairs, PFM says.
Additionally the company claims that the technology can also be developed for online programming and diagnostics.
