Mylar bags are metalized, multi-layer pouches that block light, moisture and air, which makes them a favorite for storing dry goods such as rice, beans, oats and flour. Most people pair them with oxygen absorbers and seal them inside a bucket for extra protection against pests and crushing.
The six items below cover the bags themselves, the oxygen absorbers that go inside and the bucket gear that holds everything. We have not used these products ourselves, so confirm bag size, thickness, pack count and absorber sizes on the current listing before you buy. Mylar suits dry, low-moisture foods only.

What to Look For

|---|---|
| Bag thickness | Thicker bags resist punctures and hold up better in a bucket |
| Size | Match the bag to your bucket or container, such as one gallon or five gallon |
| Seal type | Heat-sealable bags need an iron or impulse sealer; zip bags are quicker |
| Pack count | Larger packs take less handling but need more storage room |
| Oxygen absorbers | Pick absorber sizes that suit the bag volume |
| Food type | Use mylar for dry foods and skip anything with high moisture or oil |

1. Pack Fresh USA 1-Gallon Mylar Bags
A pack of heat-sealable mylar pouches in a size that suits smaller portions of rice, beans, pasta and oats.

Larger mylar bags built to line a five gallon bucket, so a bulk purchase of wheat or rice goes in a single bag. Check the listing for the thickness and the pack count.
Suits: bulk grain storage. Strengths: a bucket-ready size. Weaknesses: bulky to seal evenly. Skip it if you prefer small meal-size pouches.

A screw-top lid that fits onto a standard food-grade bucket, making it easy to open and close without prying. It suits buckets of grain or flour that you reach into often.

Mylar Bag FAQ
Do I always need oxygen absorbers?
They are widely used with mylar for long-term storage, but needs vary with the food. Follow the guidance of your bag and absorber makers.
How long will food last in mylar?
It depends on the food, the seal and the storage conditions, so we cannot promise a figure.
Can I seal mylar with a clothes iron?
Many people use a hot iron or a hair straightener, though an impulse sealer gives a more even seal.
Which foods work best?
Dry staples such as rice, beans, oats and pasta suit mylar. Check the maker’s guidance for each food.
