The present disclosure is directed to the packaging of metal thin films deposited on polymeric substrates. The packaging method prevents deleterious change of surface energy/water contact angle as a function of time for metal thin films such as rolls, coils, sheets or strips of sputtered or vacuum deposited metal thin films. Methods and kits directed toward a unique packaging and storage scheme are also disclosed. This results in maintenance of the metal film's hydrophilicity and surface energy for extended periods of time.
