For packaging dehydrated foods for backpacking, the two options that I can think of are mylar bags, and vacuum sealed bags. What are the pros and cons of each method?

Mylar bags vs. Vacuum sealed.

Pro.

  • durability (in general, it depends; thickness is varying);
  • you can pour inside boiled water without additional wares;
  • more thermal isolation and great sun protection;
  • can preserve wet and/or warm food;
  • exists solutions for vacuuming, strong sealing, etc.;

Cons.

  • slightly larger weight (thickness is varying; usually the packets weight is insignificant);
  • more volume is consumed inside your backpack (if isn't vacuumed);
  • non transparent, need signs, etc.;
  • some air still closed inside (for some products in a long run, it may make a difference);
  • can't be sealed by molding (most of time even a zip-lock will be ok);
  • price (in general);

Yes, I used both and had chosen the mylar bags. Maybe, I'm biased.
