Harvest Right Mylar Bags, 8" x 12" (50-Pack)

Light- and Moisture-Blocking Bags for Long-Term Food Storage, 8 in x 12 in

Freeze-dried food draws moisture back out of the air, so storage containers matter as much as the drying itself. Mylar bags block light, moisture and oxygen, and when heat sealed with an oxygen absorber inside they protect freeze-dried food for long-term storage. Harvest Right bags are 7 mil thick for durability.

Each 8 in x 12 in bag holds roughly a half-gallon of freeze-dried food, a practical size for most single batches, meal portions and snacks. The pack contains 50 bags.

Key Features & Benefits

• 7 mil thickness — a heavy barrier that resists punctures.
• Blocks light, moisture and oxygen — the conditions that degrade stored food.
• Heat sealable — close with an impulse sealer for an airtight seal.
• 50 bags per pack — 8 in x 12 in size for half-gallon-scale portions.

Who Should Use Mylar Bags

Mylar bags suit anyone storing freeze-dried food long term, from families building an emergency supply to homesteaders packaging a harvest. Growers use them to store dried herbs and plant material away from light and moisture.

Frequently Asked Questions

Why use Mylar bags instead of plastic bags or jars?

Mylar blocks light and is far less permeable to oxygen and moisture than ordinary plastic bags. Sealed with an oxygen absorber, it protects freeze-dried food for long-term storage. Jars work for food you'll eat soon, but they let light in unless stored in the dark.

How do I seal a Mylar bag?

Fill the bag, add an oxygen absorber, press out excess air and seal across the top with an impulse sealer. Leave headspace above the food so the seal sits on clean, flat material. Check the seal by gently tugging the bag's sides.

What does 7 mil mean?

Mil is a thickness measurement equal to one-thousandth of an inch, so 7 mil is 0.007 inches. Thicker bags resist punctures from sharp freeze-dried food better than thin ones. Harvest Right's bags are 7 mil.

How many oxygen absorbers do I need per bag?

Use at least one oxygen absorber per bag, matched to the bag's size and how full it is. Harvest Right's 50-pack oxygen absorbers are sized for gallon-size Mylar bags. Seal bags promptly after adding absorbers, since they start working as soon as they're exposed to air.
