Hi John,
I use resealable manually hand Pump evacuation bags. I bought it from a camp store hoping to store dehydrated food - not so good, they eventually lost their suk !! Air got in a lost a batch of home made beef jerky. I was about to heave them to the bin, when my lovely wife suggested using them for already cut cheeses - we tended before to eat cheese like crazy as we didn't like the dry out aspect. Now, we can cut a cheese and store the rest, cut another chunk at a later date. I find them useful but as they don't keep their vacuum for long- 1 week at best- I wouldn't use them for long term storage.
