Vacuum Packing Systems
Vacuum Sealing Machines
We supply a wide range of vacuum sealers from Lavezzini, full details can be seen at www.lavezzini.it/index/en
Vacuum sealing is used as a method of preservation and shelf life extension for food products, and as protective packaging for other non food products.
There are two types of vacuum sealer, the external bag machines, and the chamber machines.
External bag machines are cheaper, smaller in footprint, and limited in capability. These machines use a special embossed channel film either in roll form or as pre-made bags. This material is quite a bit more expensive than the regular smooth vacuum bags. For larger production quantities the saving on packaging costs will be enough to pay the additional cost of a chamber machine in a short space of time. The external machines cannot be used for products with liquids because the liquid gets sucked through the channels in the film into the vacuum pump. For liquid products it is possible to attach a vacuum tube connected to separate rigid plastic storage containers. This process however is not suitable for mass production.
The chamber type of machines are used for volume production using smooth vacuum bags. Chamber machines come in different ranges, table-top, floor standing with plexiglass lid, and the top of the range Supertech series. Within each category are different model sizes and various levels of automation and sophistication of control of the vacuum cycle.
Chamber machines - Table Top Range
The New series are manual machines with a 250 mm sealing bar and 7 cu m/hr pump are at the bottom of the range. The Prestige Series has automated digital control of the cycle, while the Top series has automated cycle with LCD control panel.
