Abstract
Provided is a method of preparing a film including the steps of providing a polymer substrate, depositing a metal layer on the polymer substrate in a metallization chamber, removing the metallized film from the metallization chamber, and applying a topcoat to said metal layer within 1 week of depositing the metal layer on the polymer substrate. A film produced by such a method exhibits improved barrier properties, such as improved water-vapor transmission rates.
Claims21
A method of preparing a film comprising the steps of:
- a) providing a polymer substrate;
- b) depositing a metal layer on the polymer substrate in a metallization chamber;
- c) removing the metallized film from the metallization chamber;
- and
- d) applying a topcoat to said metal layer;
- wherein step (d) occurs within 1 week of step (b).
A film made by the process of:
- a) providing a polymer substrate;
- b) depositing a metal layer on the polymer substrate in a metallization chamber;
- c) removing the metallized film from the metallization chamber;
- and
- d) applying a topcoat to said metal layer;
- wherein steps (d) occurs within one (1) week of step (b).
A multilayered film structure comprising:
- a) a polymer substrate;
- b) a metal layer;
- and
- c) a topcoat;
- wherein said film has a water-vapor transmission rate that is 80% or less than the water-vapor transmission rate of a film comprising said polymer substrate and said metal layer.
(canceled)
A method of preparing a film comprising the steps of:
