Default Potato Chip bags Mylar?



Advertise Here

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.

I'm definitely not an expert in the area. But it seems like a good concept. My only concern might be that its not as durable as regular mylar. I would probably just spend the extra money and get some thick mylar bags that are going to stand up to some weight.

Maybe double bag stuff. The first bag to "seal" stuff in, the second as a security blanket. Might be worth a try

Yea that is what I was thinking. Certainly not as good as the ones you can buy. But it really isnt about the money, just like to reuse stuff whenever I can. And who knows, maybe somoene doesnt have the money/resources to order mylar bags and can use this also if it works. Ill try it out and let everyone know how it turns out.

I just had a thought. They are small enough that they could possibly be used in homemade MREs to seal stuff like single servings of granola and such.

look at the rates of through flow on bags that thin. these would not be good for long term storage.

Depends on what chip bags though also. I eat "Terra Chips" and those bags are thick. Got to be at least 3 mils. Ill measure next time I get a bag.

Do you have a resource for the flowrates of various thickness of mylar? I would love to read that.

I vac sealed some coffee beans in some tostitos bags last week. Ill see how long the seal lasts for. Might take a year or so until I report back though LOL

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.

Hey thanks for the contact page! Ill call them tomorrow. 30 minutes to late. Ill let you all know what they say though!

Edit:
Just contacted Terra Chips and they did say it was a pastic film sanwithched between layers of O2 barrier and design films. They said it was PET plastic though and food grade to keep oxygen out to maintain freshness. (well it better be!) LOL

Double Edit:
I guess PET is what Mylar is made of. Mylar one of the registered trademarked item/forumaltions. http://en.wikipedia.org/wiki/PET_fil...ially_oriented) Hmmm. Interesting! Going to keep a better eye on my bagged items in the pantry lol

Tripple Edit:
Wow making dinner and saw this was 4 mils thick! Going to repack and see how it does compared to the chipbag.
