I use coke/soda/pop 2 liters for my rice. No idea if they're the best or not, but they're Mylar, and very cheap.
Sorry, I mis-typed earlier. They're not quite Mylar, but look up PET plastic, and you'll see that it and Mylar are very closely related. PET is an oxygen barrier, so it works along the line of Mylar. Used with a oxygen absorber (to absorb oxygen in the bottle), white rice stored in 2-liters can supposedly last for a long ole time.Thanks for ther tips. I don't understand what you mean though that your soda 2ltr bottles are mylar? Aren't the plastic?
i gave up on that process 20 years ago.so far i'm done rice in vacuum sealer bags; however, i'm not happy with it. The rice tips can be sharp and poke holes.
