Abstract
An inkjet ink cartridge (20) having nozzle holes (24) to eject ink is sealed against escape of the ink from the orifices by tape (1) is hard at any temperature the container might reach during shipment and handling. This hardness resists any creep of the tape material into the orifices. The tape is applied after the surface that contacts the region of the orifices is softened by application of solvent for the material of the tape. The solvent softens the surface, causing it to conform closely to the surface having the nozzle plates in the manner of conventional pressure sensitive adhesive. The solvent is then removed. The tape can have high temperature resistance and the solvent need not be one that acts on the nozzles.
