PURPOSE:To obtain a product containing an enclosure such as fluoroplastic identification indicator plate with identification indication without using releasant by a method wherein the enclosure-containing hot melt fluoroplastic is heated and pressurized through polytetrafluoroethylene releasing sheet in a mold. CONSTITUTION:An enclosure 10 consisting of polytetrafluoroethylene film 2, on which identification indication is performed, or the like is covered with two hot melt fluoroplastic sheets 6a and 6b, which are preferably made of PFA. Next, the resultant covered material 20 is put through two polytetrafluoroethylene releasing sheets 8a and 8b in molds 60. The polytetrafluoroethylene releasing sheets 8a and 8b are interposed between the covered material 20 and the molds 60 so as to prevent the molds 60 and the covered material 20 from coming into contact with each other. Next, by peeling the releasing sheets 8a and 8b off the integrated covered material, the product concerned, on which the desired identification indication is attached, is obtained. |
