PRODUCTION METHOD AND TRANSPORT METHOD FOR VERY THIN COPPER FOIL LAMINATED FILM

摘要

Disclosed is a method for producing a very thin copper foil laminated film comprising (1) a first step wherein a carrier foil is removed from a very thin copper foil laminated film with a carrier foil which is obtained by arranging a very thin copper foil with a carrier foil and a film in layers, and (2) a second step wherein the copper surface is subjected to an anti-rust treatment within a short period of time after removal of the carrier foil in the first step before the copper surface is oxidized. The thus-produced very thin copper foil laminated film can be stored for a long time, and it can be easily transported since it is light weighted.
