You can buy vacuum seal bags on Amazon which have a sealed, tear-off ziplock top and an open bottom which you seal. They seem thin, but I've never had one pop. I buy cans of mountain house, a bag of oxygen absorbers, and make my own individual meals with these

Again, I've been thoroughly impressed with these - no pops, no leaking ziplock, etc. I've used them on countless trips over the last 2 and a half years.
