2023 Preparedness - Wednesday Wisdom: Week 31

August 2nd

We are back to answering your questions on the first Wednesday of each month. Keep those questions coming.

Can I use vacuum sealer bags instead of Mylar bags and O2 absorbers for long-term storage of grains?

The simple answer is yes but there are a few things to consider:

1. Mylar bags and O2 absorbers are about $3.00 per unit. The cost to seal the same amount of product in a vacuum sealer is $.61 and absorbers are not needed.

2. Mylar bags are pre-cut and the size cannot be modified.

3. To seal properly Mylar bags must be heat sealed.

4. Wet or moist foods cannot be stored in Mylar bags.

5. Seeds should not be stored in Mylar bags with O2 absorbers.

6. Mylar is not pest-proof.

Disadvantages to vacuum-sealed bags:

1. They are more likely to have seals fail.

2. They are not light-proof. All stored foods should be kept in a dark environment. Store in a five-gallon bucket or box to protect against the light.

3. They are easier to puncture.

4. Seeds should not be stored in vacuum-sealed bags.

5. Vacuum-sealed bags are not pest-proof.
