Subject: Metallizing paper
To metallize paper, high quality "clean" paper is selected and then coated with
a polymer and dried to about 2% moisture. It is then placed in a
metallizer with extra water pumping capacity and the metal deposited on
the polymer surface. To deposit the metal, the chamber in which the
paper is placed contains a paper unwind and rewind to pass the paper
over the aluminum deposition area. The chamber contains a vacuum pump
capable of 10-5 torr pressure and the aluminum is melted on ceramic
"boats" heated to 1500 C and the aluminum evaporates and condenses on
the paper as it is passed at high speed over the molten aluminum.
Process details can be obtained from metallizing equipment suppliers.
