I was eatting a bag of Doritos and I saw the shiney backing of what I thought to be mylar. It resealed in my foodsaver and it worked like mylar. Is this stuff food grade mylar with some designs printed on it? If it is, I am just going to start recycling this stuff to vaccum seal and store my dry stuff. My family goes through Costco size bags of this stuff all the time. It certainly isn't 5 mils thick though but I wonder if concept will work.

Potato Chip bags Mylar?
Maybe double bag stuff. The first bag to "seal" stuff in, the second as a security blanket. Might be worth a try
look at the rates of through flow on bags that thin. these would not be good for long term storage.
I doubt its Mylar. However kutos on recycling.
Contact the Franchise and ask them specifically. In fact I will try and find you the number, if I don't ask them myself.

On the other hand I bet you a nickle they would go with what ever is cheapest. Same reason why once you open the bag, you find that its already half empty. In economically frugal companies, expect low end results.

It isn't mylar in the slightest.
People assume that mylar means metalized plastic. Mylar is actually a form of plastic instead. Biaxially-oriented polyethylene terephthalate.

The mylar bags used to seal up prepper food is a mis-naming for convenience. You can buy mylar bags that have absolutely no metal in them and are just see-through plastic.
What preppers use to store food in are really "metalized mylar" bags. The type of plastic is essential, namely actual mylar.
No, chip bags are not real mylar and do not store food long term. The plastic is the wrong type, it's too thin, and the metal coating is too thin as well. It will not create the proper gas barrier seal long term.
Don't be cheap. A real 5mil mylar bag AND correct sized O2A will cost as low as 50 cents per gallon volume of storage in a modest quantity. Even small quantity purchases cost under a dollar. Since a gallon bag of potato chips costs more than a dollar you are spending too much money on a phony bag that contains zero real food.
Don't try to redneck outsmart the food you may desperately need someday. Quit trying to reuse kitchen trash from junk food. No potato chip bags, no 2L soda bottles, no gatorade bottles, no thin glass pasta sauce jars. It's just trash. The "food" in them is trash too.
We wouldn't need to have this conversation if you had read about food storage in the easy to find threads at the top of the food section.
And that vacuum sealer? Not for storing dried food long term either. You can't get all the air out with a vacuum sealer. A vacuum sealer serves absolutely zero purpose in the long term storage of dried foods. Again a topic easily found and explained in the food section.

Do not use it for anything. I did a test where I left bags sit in a low heat, low humidity pantry for 6 months and 1 year. The chips in the bags went stale. The bags still get penetration making the contents horribly useless.
Re-purposing is one thing, but going cheap where you shouldn't is another
Plastic ziplok bags can be used way more than the are, being discarded after one use by most people. That's a good item to re-use or repurpose.
An empty Doritos bag to store your food preps and bank that its still gonna be good after x amount of time???
There are plenty of things that can and should be re-used/re-purposed. When it comes to your life, don't mess with something that you had what you thought was a brainstorming revelation. In other words stick with something that is known to work. Or at least until something else is proven to work better

I have an extensive back ground in packaging. Spent lots of time in the Frito-Lay plants across the US and Canada.
First, I doubt you'll get ANY useful info from Frito-Lay, they DON'T share any info on their food processing and packaging.
When Mylar first appeared in the food packaging industry product shelf life went from weeks to months.
While Mylar's vapor barrier improves shelf life it has it's own drawbacks, main one being it's very Susceptible to rips/tares. Next it doesn't have "sealing" qualities, instead it's laminated to a poly type plastic.
Sealing is always a function (besides the packaging materials own properties) Time-Temperature-Heat.
failing to apply the "right" combination of time temperature and heat can result in "QUESTIONABLE" seal Integrity.
Add to the problems are the contaminants from the chips/oils/salts/seasonings.
If one is looking for a source of packaging material I'd suggest looking up "Flexible packaging material"
While some companies use a "polyester" Mylar Some use "FFL" Foil/Film/laminates.

I'm recycling some food bags.
Not for food though.
I put other things that need protection from the elements in those recycled bags. Tools, batteries, ammo, etc.
Cheap disposable packaging for those items.
Not for LTS food.
(The plastic seals better on the non printed side and must be contaminant free. )

If you just need a waterproof sealed bag then a heat resealed chip bag is just fine.
It's when folks expect it to block air that I throw a flag on the play.

Yes they are a very high grade mylar. I worked on the packing machines at fritolay. The sun chips are now using a biodegradable bag though as a test so they will be phasing out mylar in the future.
Repurposing potato chip bags, that is some out of the box thinking. Totally the commodity that a survivalist needs most when the SHTF. When it does, my money will be on you coming out on top of the heaps of naysayers and righty tighties.
Ignore the comedian.
Just put a potato chip bag on the shelf for a couple months and see what happens.
It will deflate on its own due to outgassing. Proper mylar is gas barrier.

I have seen them bloat up tight, then outgas & deflate in short order.
From chip content producing gas pressure that broke bags seal.
