Advanced Metallized and Metal-Oxide Films

Sigma’s hollow-cathode, inverted magnetron, vacuum plasma treatment systems work to functionalize polymer webs - as well as remove low molecular weight material and other surface contaminates that can degrade the quality of vacuum deposited barrier layers. Additionally, plasma treatment of the deposited metal layer, immediately after deposition, improves barrier performance, reduces “blocking,” and metal pick-off in subsequent processes, and dramatically improves metal corrosion resistance.
