PURPOSE:To obtain a fluororesin composition resistant to the lowering of moisture-proofness even after thermal history and suitable as a moisture-proof film, etc., by mixing a polychlorotrifluoroethylene with an ethylene- chlorotrifluoroethylene copolymer. CONSTITUTION:The objective composition is produced by compounding (A) 100pts.wt. of a polychlorotrifluoroethylene with (B) preferably 0.1-0.6pts.wt. of an ethylene-chlorotrifluoroethylene copolymer having a molecular weight of 100,000-500,000 (measured by osmotic pressure) and, if necessary, (C) an additive such as colorant, filler, etc. The crystallization of the component A in the composition is suppressed even by the thermal history during or after molding and, accordingly, a molded product having excellent moisture-proofness can be produced while suppressing the loss of the moisture-proofness.
