A disaster pouch has to survive rough terrain, repeated handling, long storage and fluid-heavy cases. That is why most mass-fatality plans specify heavy supported PVC rather than light poly.

What makes a disaster bag

  • 18 mil or heavier supported PVC vinyl
  • Heat-sealed seams, leak proof
  • A heavy #10 curved zipper
  • Riveted handles with a stated rating per opposing pair
  • Toe tags and a pouch for paperwork

The 2XL Disaster Bag, 8 Handles (54 × 108 in.) and the Child Disaster Bag, 4 Handles (36 × 60 in.) are both built this way.

Where polyethylene fits

Poly bags are lighter, cheaper and chlorine-free, which matters if cremation will follow. A leak-proof poly bag like the Diamond Chlorine-Free Bag, Oversize XL is a good second tier in a cache.

Stocking a cache

Plan by size and type, not just a total count. Include adult, XL, 2XL and child sizes, a few water recovery bags if there is water nearby, and chlorine-free stock for cremation. Bags store flat in cases of 5, so rotate them and check zippers every year. See the mass fatality response equipment guide for the storage side.
