How this estimate works

Air is about 21% oxygen. The calculator takes your bag capacity, applies a food-type factor for the air trapped between pieces, then multiplies by the oxygen fraction and rounds up to standard absorber sizes (100, 300, 500, 1000, 2000 cc). Dense foods need less; bulky or porous foods need more.

Round up, never down

It is common practice to round up to the next standard absorber size or combine absorbers. Extra oxygen absorption does not harm dry stored food, while too little can leave residual oxygen that shortens shelf life.

Storage aid, not a guarantee

Oxygen absorbers help slow spoilage and staleness in dry, low-moisture foods stored long term. They are a storage aid only, not a compliance claim. Store only appropriate dry goods and follow established food-storage guidance.

Questions buyers ask

How many cc of oxygen absorbers do I need for a mylar bag?
A common guideline is roughly 300 to 500 cc of oxygen absorbers per gallon of bag capacity. Dense foods like flour, sugar, or rice sit at the lower end because they leave little air; bulky or porous foods like pasta, beans, or freeze-dried meals sit at the higher end because more air is trapped between pieces. This calculator estimates a cc figure from your bag size and food type, then rounds up to standard absorber sizes.
What size oxygen absorber for a 1 gallon mylar bag?
For a 1 gallon mylar bag, a common recommendation is about 300 cc of oxygen absorbers for dense foods and up to 500 cc for bulky or porous foods. Many people use a single 300 cc absorber or three 100 cc absorbers per gallon bag.
How many oxygen absorbers for a 5 gallon mylar bag?
A 5 gallon mylar bag typically calls for roughly 1500 to 2500 cc of oxygen absorbers depending on how much air the food leaves behind. Dense grains sit near the lower end and bulky items near the higher end. Many storage guides use 2000 cc for a general-purpose 5 gallon bag.
Do oxygen absorbers affect how mylar bags store food?
Oxygen absorbers reduce the oxygen inside a sealed bag, which helps slow spoilage and staleness for dry, low-moisture foods stored long term. They are a storage aid only. Follow established food-storage guidance and store only appropriate dry goods. Teal Packaging manufactures custom printed mylar bags and does not make regulatory compliance claims; buyers verify requirements for their products.
