Abstract

This invention relates to a process for metalizing polyolefin film in which at least one outermost layer of the unmetalized polyolefin film has at least about 90% cycloolefin polymer that has not been subjected to a process for increasing surface tension before metalization. The metalized films are useful as dielectrics in capacitors.
