Storing freezer-dried food effectively is done by sealing mylar bags with oxygen absorbers sealed inside. This is made possible by a 5mm-wide impulse sealer.
The dial on this sealer should be set to the same thickness of the mylar bag. If the seal is difficult to achieve, turn up the dial until a seal is made. To test the seal, gently tug and the seal should not be easily pulled apart.
Double sealing ensures a stronger seal. Do not reseal in the same spot to avoid melting the mylar bag and ruining the seal.
