PURPOSE:To enhance a gas barrier effect and dynamic strength, by forming an ink container of a laminate film which comprises a metallic film layer and flexible polymer films sandwiching the metallic film layer and in which the metallic film layer is produced by vapor-depositing a metal onto one of the polymer films. CONSTITUTION:A flexible flat bag form ink container 6 is constituted of a polymer film 10 in which a metal, e.g., aluminum, is vapor-deposited onto a polyethylene film layer 7 in a thickness of about 0.05-1mum to produce an aluminum film layer 8 and a nylon film layer 9 is provided on the outer side of the layer 8. The film 10 is sealed up on three sides to produce a bag form container. An ink contained in the container 6 is led out to the exterior by a tube 2. The aluminum film layer 8 is contiguous with the polymer film layer, e.g., polyethylene film layer 7, on a molecular basis, exhibiting a merit that neither cracks nor pinholes are generated in principle. |
