Abstract
A method for sealing an ink cartridge is disclosed. A cover film is bonded to the ink cartridge in such a manner as to cover an ink inlet hole formed in the ink cartridge. An opening is formed in the cover film in such a manner as to communicate with the hole of the ink cartridge. The method includes preparing a seal film and bonding the seal film to the cover film with a bonding strength smaller than the bonding strength of the cover film with respect to the ink cartridge in such a manner that the seal film becomes peelable from the cover film, thereby sealing the opening of the cover film.
