Vacuum Pack Machines: Inside Secrets You'd Be Wise to Learn
One of the terms you'll come up against is chamber vacuum packer also called external vacuum packer or external bag machine.
For home use, external bag machines are ideal. Vacuum chamber machines are big and heavy and are more often found in commercial premises.
With the external bag machine, it has an open port to which is attached the vacuum bag. When the appliance is switched on the air is evacuated. Sometimes the heat sealing of the bag is done at the same time, with other machines you have to seal the bag as a separate action.
A vacuum packaging machine helps cut down on waste so it's important as part of the economics to consider how much you'll have to payout in total.
And the first thing to say is you can buy really cheap machines but you get what you pay for.
If you want a machine that provides a good vacuum so the food lasts longer, you need one which has a good electric pump.
You can buy cheap vacuum packers for $30-00 but be aware that for a machine that works well and is going to keep working well for any appreciable time, the cost of the electric pump alone, will be greater than the cost of a cheap vacuum sealer.
You get what you pay for. A machine that costs two hundred to three hundred dollars, will probably serve you well for a number of years.
Also there's the matter of warranty to consider. It's wise to make sure you have a 2 year warranty as a manufacturer with enough confidence in their product will make a machine that can stand up to reasonably robust use for that length of time. Parts and labour one can reasonably expect would be included in such a warranty.
