These bags are strong, durable, and easily sealed with a vacuum-sealer, iron, or hair-straightening iron.
Durable Long-term Storage: 7 mil mylar bags provide a substantial increase in puncture protection, improved durability, and greatly increase long-term oxygen and moisture resistance. Superior oxygen barrier provides over 100 years of protection when used with packfreshusa oxygen absorbers.
