Considering my somewhat limited needs, I went for cheap. I got a
Ziploc Brand at Walmart for $49.95.
And it can use (comes with a hose) Food Savers vacuum canning adapters.
The plan there is to use Ball Mason jars for vacuum marinading, vacuum pickling, and vacuum dry canning.
I find the rolls of bags a tad pricey. But depending on what you had in the bag, you can wash, sanitize, and reuse the bags in a smaller configuration if you dare to.
If you've got deep pockets, you can go up to a vacuum chamber sealing machine. Those will vacuum seal bags with liquid in them.
Shotgun Red has a demonstration of a Food Saver VS: a Chamber Machine.
I, LOL, I packaged up a block of cheddar cheese I had smoked. Then I packaged up the block I had shredded. :)
The block I had shredded turned back into a lump with the atmospheric pressure trying to get back in the sealed bag.
Imagine taking shredded cheese in your hand, then crush it. Makes a lump.
But with a vacuum sealer, it's about 100 times as squished. :confused::eek:
Moral of that story is: Put grated cheese in a Mason jar. ;)
