| 摘要 | PURPOSE:To obtain a sealing film excellent in its resistance against aromatic series solvent and durable in prolonged used by constructing the sealing film in such a way that at least its one side exposed to stored gas is made up with a layer comprising a specific high polymer film material. CONSTITUTION:At least one side which is exposed to stored gas, of a sealing film of pontoon type gas holder 8 is made up with a layer 20 comprising a single or fiber-reinforced elastomer of either among polyester series, polyamide series, and polyerethane series. In case said sealing film is formed in a composite layer made of different kinds of high polymer film materials or a composite layer made of a high polymer film material 20 and a reinforcing material 21, at least one side of the sealing film is formed in a layer made of the thermoplastic elastomer, allowing said layer to be used as a side where the gas holder is exposed to the stored gas. | ||||||
