Ok, I get it, Mylar is only Dupont’s product name/trade name
Basically all these other products including the one I am using are Mylar too as long as they have a metal coating. I just checked, mine all have a metal film too.
They are just your standard long term food storage bags that I bought from the grocery store. 10x cheaper than the “Mylar” brand.
Do tell. Brand name? Store name? Mfr. name? Size? Price per bag?
I imagine the ones you bought are a couple mils thick vs. the more expensive 4-5 mil...which should be ok.
Inquiring minds want to know.
