1 Gallon Mylar Bags in 4 Useful Styles

Not every food storage project needs the exact same bag. That’s why this listing lets you choose from four different 1 gallon Mylar bag styles, each made for a slightly different use.

Whether you are packing rice and beans for emergency storage, portioning freeze dried foods, packaging dry goods for resale, or organizing pantry staples, these 5 mil per side Mylar® bags provide strong, reliable barrier protection against the three biggest enemies of long-term dry food storage: oxygen, moisture, and light.

When properly heat sealed and paired with the correct oxygen absorber, these bags help extend the shelf life of dry foods and protect your supplies for years.

Choose Your Style

10"x14" Open Top Mylar Bag — Exactly 1 Gallon

This is the compact, classic 1 gallon option. It is open at the top and designed to be filled, oxygen absorber added, and heat sealed closed. This size is a great choice when you want a true 1 gallon bag without extra height.

Best for:

• Rice
• Beans
• Lentils
• Pasta
• Oats
• Dehydrated foods
• Freeze dried ingredients
• Pantry rotation bags

10"x16" Open Top Mylar Bag — Approx. 1.125 Gallons

This taller open-top version gives you a little extra room above the food for easier filling and sealing. The extra height can be useful when packing bulkier foods or when you prefer more headspace to make a clean seal.

Best for:

• Pasta
• Cereal
• Freeze dried meals
• Oats
• Powdered foods
• Bulkier dry goods
• Easier sealing with extra headroom

10"x16"x4" Gusseted Ziplock Mylar Bag — Approx. 1.25 Gallons

The gusseted ziplock style expands at the bottom, giving the bag more usable space and making it easier to stand and fill. The zip seal allows the bag to be resealed after opening, while the top can still be heat sealed for long-term storage.

Best for:

• Freeze dried foods
• Snacks
• Retail packaging
• Foods you may open and close repeatedly
• Small business packaging
• Pantry goods that benefit from a stand-up bag

10"x16" Tamper Evident Ziplock Mylar Bag — Approx. 1 Gallon

The tamper evident option is designed differently from a standard ziplock bag. It is pre-sealed above the zipper at the top and open at the bottom. You fill the bag from the bottom, then heat seal the bottom closed.

This gives the finished package a tamper evident top seal. The end user can tear or cut open the top seal to access the zipper underneath.

Best for:

• Retail food packaging
• Customer-facing products
• Freeze dried foods for resale
• Samples and specialty dry goods
• Packaging where visible tamper evidence matters

Why Use Mylar Bags for Food Storage?

Mylar bags are one of the best choices for long-term dry food storage because they provide a protective barrier against oxygen, moisture, and light. These are three of the main factors that reduce food shelf life.

For best results, use these bags with dry foods that are suitable for long-term storage and add the proper oxygen absorber before heat sealing. Store sealed bags in a cool, dry place and use a rigid container or bucket when extra protection from rodents, crushing, or rough handling is needed.

Common Uses

These 1 gallon Mylar bags are ideal for storing:

• White rice
• Dry beans
• Lentils
• Pasta
• Oats
• Flour
• Sugar
• Powdered milk
• Dehydrated vegetables
• Freeze dried fruits
• Freeze dried meals
• Emergency food rations
• Camping and backpacking meals
• Dry pet food portions
• Snacks and dry retail foods

Note: Oxygen absorbers are generally recommended for low-moisture dry foods. Do not use oxygen absorbers with brown sugar or high-moisture foods.

Recommended Oxygen Absorber Guidance

For most dense dry foods in a 1 gallon Mylar bag, a 300cc oxygen absorber is a common choice. For foods with more air space, such as pasta, oats, freeze dried foods, or irregularly shaped foods, consider using a larger absorber or multiple absorbers.

When in doubt, it is usually better to slightly oversize the oxygen absorber than to undersize it.

FAQ Section

What size are these 1 gallon Mylar bags?

This listing includes four style options: 10"x14" open top, 10"x16" open top, 10"x16"x4" gusseted ziplock, and 10"x16" tamper evident ziplock. The exact capacity depends on the style selected.

What is a tamper evident Mylar bag?

A tamper evident Mylar bag is pre-sealed at the top above the zipper and open at the bottom. You fill the bag from the bottom, then heat seal the bottom closed. This creates a finished package where the customer must break or cut the top seal before accessing the ziplock.

Are these bags heat sealable?

Yes. These Mylar bags can be heat sealed with an impulse sealer, flat iron, or household iron. Ziplock styles should still be heat sealed above the zipper for long-term food storage.

Are ziplock Mylar bags good for long-term food storage?

Yes, as long as they are also heat sealed. The zipper is convenient for opening and reclosing the bag after use, but the heat seal is what creates the stronger long-term storage closure.

What foods can I store in 1 gallon Mylar bags?

These bags are commonly used for rice, beans, oats, pasta, dehydrated vegetables, freeze dried foods, flour, powdered foods, emergency meals, and other dry goods.

Do I need oxygen absorbers?

For long-term storage of dry foods, oxygen absorbers are usually recommended. They help remove residual oxygen from inside the sealed bag and improve shelf life.

Can I use these for freeze dried foods?

Yes. These bags are a good choice for freeze dried foods, especially when paired with oxygen absorbers and properly heat sealed.

Are these bags reusable?

They may be reused for short-term storage if they are clean, dry, and undamaged. For long-term food storage, especially with oxygen absorbers, a fresh bag and fresh seal are recommended.
