PackFreshUSA: Quart (8″ x 12″) AirTight Seal-Top Mylar Bags for Long-Term Food Storage – Premium Century 7 Mil Thick (Per Side) – Resealable – Heat Sealable – Food Grade – Rounded Corners – Free Guide -Pack of 100

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 over 140 psi, equivalent to the weight of 5 cinder blocks per square inch. These bags are strong, durable, and easily sealed with a vacuum-sealer, iron, or hair-straightening iron.
SEAL-TOP/TAMPER PROOF: New “Bottom-Filling” bags are tamper evident and easier to seal. Other brands require you to seal in a narrow area next to the seal top. This makes for an easy heat-seal, and the result is cleaner and much easier to open and reseal. You will appreciate the convenience when it comes time to open. Easily seal with vacuum-sealer, iron, or a hair-straightening iron.
*BE AWARE: ALL Mylar bags MUST be heat-sealed for food storage. A seal-top is only for resealing food after you open it.
DURABLE LONG-TERM STORAGE: 7 Mil (per side) single-colored mylar bags provide a substantial increase in puncture protection, improved durablility, and greatly increase long-term oxygen and moisture resistance. Superior oxygen barrier provides over 100 years of protection.
