Metallization means that a metallic material such as aluminum is added to the underlying support member. This is the process of adding It bonds a thin film of metal foil to the surface of its supporting member This can be achieved by letting This bonding is done using a suitable adhesive. The result is a laminate of support material and foil.

Alternatively, electrical resistance, electromagnetic induction or electron beams can be used to create gold in a high vacuum. The metal is vaporized to form a metal layer on the support member. This method removes significant moisture Valid only for support members that do not contain The presence of moisture prevents metallization. The vacuum draws out vapors and other by-products that must be removed before It will be taken away. Also, in the final product, there are no defects in the supporting member. Regularity begins to emerge.

As a result, if it is desired to directly metallize the paper support using a vacuum, outgassing ( The paper is first dried until the outgassrng) is negligible.
