PackFreshUSA: Five Gallon Heavy Duty Seal-Top Mylar Bags – 2000cc + 500cc High Capacity Oxygen Absorber Packs – Rounded Corners – Heat Sealable – Long-Term Food Storage (10)

EXCEPTIONAL QUALITY: Our bags have rounded corners to protect your other stored items from puncture or damage. The strong Mylar film has a burst strength of 70 psi, equivalent to the weight of 2 1/2 cinder blocks per square inch. These bags are strong, durable, and easily seal with a vacuum-sealer, iron, or hair-straightening iron.
DURABLE LONG-TERM STORAGE: 5.5 Mil Seal-Top Heavy Duty 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.
LOW OXYGEN TRANSMISSION RATE: Mylar bag films provide three layers of protection and offer an extremely low Oxygen Transmission Rate (OTR) due to its thick foil laminate layer. This safeguards your food against the elements for long-term preservation.
OXYGEN ABSORBER PACKS (OAP): High capacity 2000cc and 500cc OAP will absorb 180% – 300% of their rating to have a substantial buffer of safety and to allow handling time. Convenient 10-Packs allow you to open smaller quantities at a time, reducing exposure, waste, and the need to reseal those you are not using.
