The dry lamination process makes this material suitable for boiling, freezing, or use in a microwave. The outer layer of polyester (Mylar) provides the structure with oxygen barrier properties 10x that of a polyethylene bag twice as thick. However, both the oxygen and moisture barrier properties are considerably less than any foil laminate structure.  This material provides good protection against corrosion and oxidation, used on items requiring moderate protection against the environment.
