Food Storage Packaging Methods

Glass Cans

Foil Pouches

Polyethylene terephthalate (PET or PETE) and foil laminate pouches are exceptional food containers. The polyethyene (PET) layer is food-grade plastic with no known toxicities. The foil layer dramatically reduces the transmission of oxygen and moisture through the film. One trade name is Mylar and its often used as a generic name.

Glass Canning Jars With Screw-on Lids

All glass jars used to can foods work well for storing dry foods provided a tight sealing lid is used, e.g. Mayonnaise jars. However, only mason-type canning jars can be used for canning foods in jars. Be sure jars are thoroughly cleaned of all previous food residue before using it for food storage.

Plastic (PETE) Bottles

PETE is the same plastic in foil pouches molded to form rigid bottles. The bottles are identified on the bottom, next to the recycle emblem, with the letters PET or PETE. This type of container has good oxygen barrier qualities and can be used with oxygen absorbers to store bulk dry foods. The low oxygen content of the sealed containers protects the stored food from insect infestation and helps preserve product quality. These containers are well suited for products that are rotated on a regular basis, while still providing many years of storage capability. Use only PETE bottles that have been previously commercially packaged with food. Bottles need to have screw-on lids with plastic, not paper or foam, lid seals. Verify that the lid seal will not leak air by placing a sealed empty bottle under water and pressing on it. Wash and rinse bottles to remove any residue. Drain and dry bottles. Place an oxygen absorber packet into each bottle. Fill bottles with bulk dry products that are low in moisture and oil content. Wipe top sealing edge clean. Screw lids on tightly. Tape the lid edge to prevent loosening.
