I'm about to start storing and vacuum sealing (with oxygen absorbers) food in a 5 gal bucket. When I look for the Mylar bags online what thickness to I need to make sure I get? What do I look for in the oxygen absorbers? I seem to remember reading you need to use type D because they are made better or something. Where is a good place online I can buy the mylar bags and oxygen absorbers? I don't need to many, just 5 5gal and maybe 5 1 gal bags for the time being. Thanks for your help.
