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?

I hadn't thought of that, but I may well start vacuum-sealing my nice clothes for meeting with C&I.

Not quite sure I would do that. I recall a story from a tactical aviator to the effect that, upon the advice he had received from a crew chief, he had ''emergency clothing'' consisting of a civilian shirt, slacks, sox and undies vacuum packed by the safety systems folks into a single bag that he carried in his flight bag where space was at a premium, just in case he might have to do an unforeseen and unforecasted overnight somewhere. Well, a year and a bit later, the crew chief advice did pay off, as he and his crew got stranded in a small village due to inclement weather. After checking in at the local hotel, he finally cut open the bag and extracted his clothes. Trying as hard as he could that evening, he was never able to get rid of the well encrusted wrinkles that developed through the process and time spent in the bag.

Re: Vacuum Sealing Gear and Supplies

I have never had a wrinkle problem, but I am careful to roll things up not fold them. That being said I also don't leave them in the bag for long, a few weeks at the longest.

I should also point out that the vacuume saver jars are terrible. I have had a few and they all fail in weeks. However the large mouth jar sealer is amazing, but it does raise the problem of having glass jars on board.

Yes all the plastic containers they sell fail quickly. I like the idea of the jar sealer though. It is nice to have a stiff walled container for soft items I don't want to crush.

They are also almost infinitely reusable. At home I have most of my pantry in bell jars. The smaller jars are great, you can seal single use sizes like one cup of rice, or popcorn in each jar. It just takes a few minutes when you bring home a big bag of stuff, but then nothing goes stale.

Just off hand some of my favorites for this...

1) rice
2) peanuts (other snack food)
3) popcorn
4) chocolate covered nuts/raisin
5) granola
6) flour (in 2 and 4 cup sizes)
7) sugar (1 cup at a time)

Bah. Now I sound like a vacuume saver nut.... I really do think these things are amazingly useful once you start playing with them.

Re: Vacuum Sealing Gear and Supplies

I'm not a fan of heating plastics in food, but FoodSaver (Jarden) says that their bags are made from polyethylene glycol and nylon, and don’t contain BPA, phthalates, or other plasticizers with EA (estrogenic activity)-leaching additives. Still, I avoid it. I don't want to read a study about some plasticizer or other surprise down the road.

That being said, I am vac sealing all kinds of leftovers in small portions for the freezer. I'll just remove it before re-heating.

Another incredible new application for the FoodSaver ... it can reseal mylar potato-chip type bags (vac sealed or just sealed without vac).

Yesterday, I just stuck three pairs of vac sealed socks in my forward berth. My life is forever changed.

You can also seal wine bladders. I've carried lemonade and various juices in repurposed wine bladders.

Re: Vacuum Sealing Gear and Supplies

David, if you're using the mylar chip bags for your socks, they may be a little salty and crunchy when you go to wear them. You might want to turn the bag inside out next time.

Re: Vacuum Sealing Gear and Supplies

Kind of an aside, but at least the Zip-Lock brand freezer bags are microwave safe (and BPA free), so won't leach out anything if you boil them.
