PAK48MT2500
PAK48MT2500 material provides good protection against corrosion and oxidation, used on items requiring moderate protection against the environment, 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. (See PAKVF4 or PAKDRY7500)
