Re: Vacuum Sealing Gear and Supplies
The ziplock bags, even the thicker freezer bags, are not impermeable. I'd guess the vacuum bags are made from a different material for different purposes. And that the ziplock bags are either untested or unfit for boiling, maybe the plasticizers migrate out.
Plasticizers routinely migrate out of "rubbers" and plastics and perhaps that would be made worse in a vacuum bag. Or maybe not. If you just sealed them without a hard vacuum, and used Armorall (etc) or talc before putting them away....Is there still time to apply for federal grant money to study this?
