（従来の技術）
従来から防湿性フィルムとして塩化ごニリデン樹脂層（
ＰＶＤＣ￥ｒＪ）がポリエヂレデレフタレート（Ｐ Ｅ
Ｔ ）やポリプロピレン（ＰＰ）フィルムに積層され
包装フィルムとして広く使用されている。(Conventional technology) Nylidene chloride resin layer (
PVDC￥rJ) is polyethylene derephthalate (P E
It is widely used as a packaging film by laminating it on T) or polypropylene (PP) film.
一方、ポリクロロトリフルオロエチレン樹脂口（ＰＣＴ

フィルムとして広く使用されている。On the other hand, polychlorotrifluoroethylene resin (PCT)
FEIM) is also widely used as a moisture barrier film for electroluminescence (EL).
（発明が解決しようとする問題点）
これら従来の技術で使用されるＰＶＤＣｆｍは、低温で
の防湿性に対し、高温での防湿性は若干悪くなるがそれ
程度化なくほぼ一定の防湿性を有する。(Problems to be Solved by the Invention) The PVDCfm used in these conventional technologies has almost constant moisture resistance at high temperatures, although the moisture resistance at high temperatures is slightly worse than at low temperatures. .
一方、ＰＣＴＦＥ層はＰＶＤＣ層に比し低温での防湿性
が秀れ、高温では劣る。On the other hand, the PCTFE layer has better moisture resistance at low temperatures than the PVDC layer, but is inferior at high temperatures.
従って、ＰＶＤＣ層は低温側で、ＰＣＴＦＥ層は高温側
でそれぞれ防湿性に問題点がおり、その改善が望まれて

It may also be laminated by thermal bonding or bone cement via a modified polyolefin layer (modified POI) having a thickness of m, or by co-extrusion.
ｐｖｏｃ層の上にはヒートシール層として２０〜１００
μｍ厚みの変性ＰＩやエチレンビニールアルコール層等
を設けても良い。20 to 100 as a heat seal layer on top of the pvoc layer.
A modified PI, ethylene vinyl alcohol layer, etc. with a μm thickness may be provided.
更に保護層としてポリプロピレン層やポリエチレン層を
設けても良い。Furthermore, a polypropylene layer or a polyethylene layer may be provided as a protective layer.
