Abstract
A process for producing metalized packaging films comprises the step of sputtering a metal, such as aluminum, gold, silver, copper, platinum, nickel, titanium or tantalum onto a biodegradable poly(hydroxy acid), preferably poly(lactic acid) film, which may then be adhered to a cellulosic substrate if desired.
