This series uses evaporation to deposit 1µm aluminum on both sides of PET/PP and similar substrates 4.5-8.0µm thick, metallizing the film surface with a 'PVD aluminum–polymer support layer–PVD aluminum' sandwich and overcoming challenges in large-scale, rapid deposition of thick aluminum films. Composite aluminum foil is more difficult to manufacture than conventional rolled aluminum foil. PVD evaporation melts metal at high temperature and deposits aluminum on both sides of PET/PP film to make both surfaces conductive. No wet processes such as chemical electroplating are needed: dry processing alone completes both aluminum layers in one operation.
