20 Mylar Bags 2.5 Gallon Extra Thick 15 Mil - Long-Term Food Storage

Our review of these 20 Mylar bags finds them best suited to home preppers and families who need reliable long-term food storage without fuss. The biggest reason to buy is the combination of thick, triple-layer construction and included 1000cc oxygen absorbers that together reduce oxygen and protect dry goods for extended periods. For anyone storing rice, beans, powdered milk, or emergency rations, the package offers a ready-to-use solution with resealable zippers and optional heat-seal capability.

Key Features

• Pack content: Includes 20 Mylar bags, 20 individually vacuum-packed 1000cc oxygen absorbers and 20 labels, so you can store and organize many batches right away.
• Durable design: The 14.8 mil total thickness with 7.4 mil per side and triple-layer construction provides puncture resistance and better barrier protection for long-term storage.
• Oxygen absorbers: Individually sealed 1000cc absorbers are sized to remove oxygen from the 2.5-gallon bags to help keep food fresh and slow oxidation.
• Easy to use: Zipper seal plus a U-shaped tear for quick opening, with the option to heat-seal for extra protection against moisture and air.
• Stand-up gusset: The bags stand upright for easier filling and labeling, which simplifies packing bulk portions into buckets or cupboards.

Who It's For

These Mylar bags are ideal for home emergency preppers, bulk food buyers, and anyone who wants to portion dry staples like rice, beans, pasta or powdered foods into stable, long-term packages. The included 1000cc oxygen absorbers and labels make the set convenient for immediate use and organized storage.

Those who need single-use vacuum sealing for perishables that require refrigeration, or who prefer zip-top plastic alone for frequent everyday access, might prefer a different system. Also, if you need larger gallon capacity than 2.5 gal, consider larger bag sizes.
