<p>PURPOSE:To provide the vessel which has an excellent gas barrier property and excellent long-term preservable stability and is transparent and, therefore, allows the easy checking of the intrusion of foreign matter and the change of contents by using a transparent laminated film provided with thin layers of ceramics on one or both surfaces of a plastic film. CONSTITUTION:The transparent laminated film provided with the thin layers of the ceramics on one or both surfaces of the plastic film is used. The films using plastics, such as polyester, polycarbonate, polyamide, polyimide, and polyvinylidene chloride, in addition to plastics, such as polyvinyl chloride, polyethylene, polypropylene, and ethylene/vinyl acetate copolymer, are usable as the plastic film. The thickness of the plastic film is adequately in a 10 to 1000mum range in the case of forming the plastic film into a bag. Further, this plastic film is formed by laminating >=2 kinds of plastic films. The formation of the thin layer of the ceramics is executed by known methods, such as vacuum vapor deposition, ion plating or ion sputtering. The thickness of the thin layer of the ceramics is adequately about 0.001 to 0.8mum, more preferably 0.01 to 0.5mum in terms of the balance between the gas barrier property and flexibility or transparency.</p> |
