Oxyfree Oxygen Absorbers - Wholesale Bulk Cases (300cc, 2000cc)

Wholesale Oxygen Absorbers for Mylar Bags and Long-Term Food Storage

Save on high-performance OxyFree Oxygen Absorbers with full wholesale cases designed for commercial packaging, freeze-drying businesses, preparedness retailers, food-storage groups and high-volume home users.

Choose from 300cc oxygen absorbers for smaller Mylar bags or 2000cc oxygen absorbers for 5-gallon bags and bulk food storage. Each case contains multiple factory-sealed packs, allowing you to open only the quantity needed for each packaging session.

Choose Your Oxygen Absorber Case

300cc Wholesale Case

The 300cc case contains 1,500 total oxygen absorbers, packaged as 75 sealed packs of 20.

A 300cc absorber is an excellent general-purpose size for:

• 1-gallon Mylar bags
• Quart-size and smaller food-storage bags
• White rice
• Dry beans
• Pasta
• Rolled oats
• Powdered foods
• Freeze-dried meals, fruits and vegetables
• Dehydrated foods that have been thoroughly dried

For most properly filled 1-gallon Mylar bags, use one 300cc oxygen absorber. Bags containing lightweight foods with significant airspace may require additional capacity.

2000cc Wholesale Case

The 2000cc case contains 240 total oxygen absorbers, packaged as 24 sealed packs of 10.

The larger 2000cc size is designed for:

• 5-gallon Mylar bags
• Food-grade storage buckets
• Bulk grains
• White rice
• Dry beans
• Pasta
• Rolled oats
• Wheat berries
• Freeze-dried foods
• Emergency and institutional food-storage programs

Use one or two 2000cc absorbers per 5-gallon bag, depending on the amount of food, food density and remaining headspace. Dense foods such as rice and wheat contain less trapped air than bulky foods such as pasta or oats.

Why Choose OxyFree Oxygen Absorbers?

Stronger Performance and More Working Time

According to independent testing, OxyFree absorbers significantly exceeded their labeled capacity. Our 300cc oxygen absorber measured an actual oxygen-absorption capacity of approximately 1,106cc during testing.

That excess capacity provides two important benefits:

• Greater protection against residual oxygen inside the package
• More practical working time during large food-packaging projects

Instead of racing to seal every bag immediately, you have more time to fill, arrange and properly heat-seal your Mylar bags.

Convenient Sealed Packs

Opening a large package exposes every absorber inside it to oxygen. Our wholesale cases divide the absorbers into smaller sealed packs:

• 300cc absorbers are packed 20 per package
• 2000cc absorbers are packed 10 per package

This makes it easier to use only what you need while keeping the remaining absorbers protected for future packaging sessions.

Designed for Long-Term Food Storage

When used inside a properly sealed high-barrier package, oxygen absorbers help:

• Reduce residual oxygen
• Slow oxidation and rancidity
• Protect flavor, aroma and color
• Preserve sensitive nutrients
• Discourage insects and oxygen-dependent spoilage organisms
• Extend the usable storage life of properly prepared dry foods

Oxygen absorbers work especially well with genuine Mylar® bags, metal cans, glass jars and other airtight, high-barrier food-storage containers.

How to Use Oxygen Absorbers

1. Fill and organize all Mylar bags before opening the absorber package.
2. Prepare your heat sealer and leave enough room at the top of each bag for a complete seal.
3. Open one sealed pack of oxygen absorbers.
4. Place the correct absorber size inside each bag.
5. Press out as much excess air as practical.
6. Heat-seal the bag immediately.
7. Double-seal the bag when using an impulse sealer.
8. Store any unused absorbers in a heat-sealed barrier bag or a tightly closed glass mason jar.

Do not judge an oxygen absorber solely by whether the bag becomes visibly vacuum-tight. Oxygen absorbers remove oxygen, but they do not remove the nitrogen that makes up most of the air. Powders and tightly packed foods may also show very little visible contraction even when the absorber is functioning properly.

Important Food-Safety Information

Use oxygen absorbers only with properly dried, low-moisture or correctly freeze-dried foods.

Do not use oxygen absorbers to store moist foods at room temperature. Removing oxygen from a moist food package can create conditions that allow dangerous anaerobic bacteria to grow.

Oxygen absorbers are also generally unnecessary for granulated sugar, salt and similar products that do not require oxygen removal. Sugar may become extremely hard when stored with an oxygen absorber.

The packets are intended to be placed inside food packages but are not edible. Do not cut open the packets or allow their contents to mix with food.

Frequently Asked Questions

Which size should I choose?

Choose 300cc absorbers for quart and 1-gallon Mylar bags. Choose 2000cc absorbers for 5-gallon Mylar bags and food-storage buckets.

How many absorbers should I use?

A properly filled 1-gallon bag commonly uses one 300cc absorber. A 5-gallon bag commonly uses one or two 2000cc absorbers. Lightweight foods with more trapped air may require greater absorber capacity.

Can I use more capacity than required?

Yes. Using slightly more oxygen-absorbing capacity than necessary will not harm properly dried food. It can provide an additional margin for headspace, trapped air and small amounts of oxygen that may enter through the packaging over time.

Why didn’t my Mylar bag shrink tightly?

Oxygen represents only part of the air inside the bag. Nitrogen remains after the oxygen has been absorbed. Powders, flour, freeze-dried foods and densely packed products may also prevent the bag from visibly pulling inward.

Check the sealed area for leaks and inspect the space near the top of the bag. If the two sides are being drawn together, the absorber is likely working even when the entire package does not appear vacuum-sealed.

Wholesale Value Without Wholesale Waste

Whether you are packaging 1-gallon portions for resale or filling 5-gallon emergency food-storage buckets, these wholesale OxyFree cases give you the capacity, pack sizes and flexibility needed for efficient large-scale food storage.

Select 300cc or 2000cc from the options above to order the right wholesale case for your packaging operation.

Here are the main benefits of using our oxygen absorbers:

• Lowers oxygen Levels inside your sealed Mylar bag to less than 0.1; in contrast, vacuum sealing only reduces oxygen to around 2%.
• Keeps the freshness and original taste, smell, and color of your stored food items
• Prevents your food from becoming stale, rancid, or spoiled
• Prevents the growth of mold, mildew, bacteria, aerobic pathogens, spoilage organisms, and anaerobic microorganisms.
• Dramatically extends your stored items' shelf life
• Emits no harmful gases or bi-products
• Are FDA approved for direct contact with food and related products
• Eliminates the need for unhealthy preservatives such as sorbates, benzoates, BHA, BHT, PFAS, sulfur dioxides, and more.
• Works well with vacuum packaging or gas flushing to even further absorb any already oxygen sealed inside or that may eventually permeate the package
• Helps keep the nutritional qualities of polyunsaturated oils and fats
• Prevents the oxidation of your food's A, C, and E Vitamins
• Works well with dry or semi-moist foods
• Great for grains, legumes, beans, nuts, seeds, dried meats, jerky, milk powder, baking mixes, flours, sugar, salt, spices, seasonings, herbs, coffee, tea, candies, confectionaries, snacks, breads, cakes, cookies, pastries, pasta, pharmaceuticals, vitamins, supplements, bird seed, pet foods, and more
• Great for storage of tools, artwork, medical diagnostic kits and devices, etc.
• VERY Safe, Non-Toxic & SUPER EASY TO USE
