Durable&mdash;long lived plastic films carrying sputter-deposited metal layers such as reflective metal layers on both sides are disclosed. The slip side of the plastic film is not preglowed. The nonslip side is preglowed. This combination of glowing and not preglowing leads to the desired long life.

The durability of thin metal coatings and particularly substantially transparent copper and silver plus noble metal coatings and their ability to withstand corrosive environments is improved by overcoating the metal layers with a double coating of dielectric. The first coating is made up of dielectric based on indium and/or zinc. The second coating is made up of dielectric based on indium and tin. These overcoatings are more effective than a single coating based on one metal or a single coating based upon the two metals.
