Description
製造例1(食品用抗菌生分解性フィルム)
20重量%のサイクロデキストリン水溶液にイソチオシアン酸アリルをサイクロデキストリン固形分に対して11重量%混合攪拌して包接化合物水溶液を得た後、ポリ乳酸二軸延伸フィルム(商品名「エコロージュ」、三菱樹脂株式会社製、融点155〜175℃)の表面に塗布し、乾燥させて10〜30μm厚のコート層を形成させ、本例のフィルムを得た。尚、前記ポリ乳酸二軸延伸フィルムの塗布面には、事前に、バイオテックカラーHGC(大日精化製)を用いて周知手段で模様を付したものを用いた。
バイオテックカラーHGC(大日精化製)を用いて周知手段で模様を付したポリ乳酸二軸延伸フィルム(商品名「エコロージュ」、三菱樹脂株式会社製、融点155〜175℃)の表面(模様を付した側)にランディPL−2000(ミヨシ油脂株式会社製)を塗布して乾燥させた後、レーヨンパルプ紙を重ねてローラで両者を挟んで加圧加熱成型して積層体を得た。次に、20重量%のサイクロデキストリン水溶液にイソチオシアン酸アリルをサイクロデキストリン固形分に対して11重量%混合攪拌して包接化合物水溶液を得た後、前記積層体の表面(紙側)に塗布し、乾燥させて10〜30μm厚のコート層を形成させ、本例の成型フィルムを得た。
製造例1のフィルム及び製造例2の成型フィルムに関して、抗菌性の評価を行った。ここで、抗菌性試験は、サンプルを20×20cm大に製袋して、その中にマグロドリップを混釈した液体培地シャーレを入れて10℃で48時間放置した後、液体培地中の生菌数を測定して抗菌効果の有無を調査し、〇は抗菌効果が認められることを示し、×は認められないことを示している。結果を表1に示す。
製造例1のフィルム及び製造例2の成型フィルムに関して、抗菌性の評価を行った。ここで、生分解性試験は、10cm×10cm、厚さ0.2cmの平板フィルムを調製し、このフィルムを土中に埋設して、生分解性をその重量変化によって調べた。重量の減少(2ヶ月後の重量減量率%)は、平板フィルムが生分解を受ける程度を示す。結果を表1に示す。
