Description
オブラートは澱粉からなるフィルムであるが、ガスバリア性が十分ではなく、包装された食品の長期安定性に改良の余地がある。
性を有することが好ましい。
また、本発明の包装容器は、上記の蓋材用包装用フィルムを折り返して開封する蓋材として用いた蓋を有するものである。
(酸素透過度)
作成した厚み150μmのカゼインフィルムの酸素透過度を、JIS-K7126B法に準拠した測定方法で測定した。
ビーカーに水を入れ、厚み150μmのカゼインフィルムのサンプルを入れ、ゆるやかに攪拌させ24時間後に確認した。
ビーカーにサラダ油を入れ、厚み150μmのカゼインフィルムのサンプルを入れ、ゆるやかに攪拌させ24時間後に確認した。
ヒートシール機にて厚み150μmのカゼインフィルムを重ね合わせて120℃でヒートシールを行い、シール性の有無を確認した。
厚み150μmのカゼインフィルム及び厚み40μmのカゼインフィルムのそれぞれを折り曲げ、もどりの有無を目視で確認した。
その結果、厚み150μmのカゼインフィルムの酸素透過度が1.68cc/m2・day・atmであった。この酸素透過度は、通常のPETフィルムの約6倍程度の酸素バリア性を有することを示していた。
Claims (4)
- カゼイン又はカゼインの塩及びグリセリンを含み、でんぷんを含まず、厚さ150~1000μmであり、酸素バリア性を有し、折り返して開封する蓋材において、開封したままの形状を保持でき、静置したままでは元の状態に戻らない程度のデッドホールド性を有することを特徴とする蓋材用包装用フィルム。
- 可食性材料からなる請求項1記載の蓋材用包装用フィルム。
- 耐油性を有する請求項1又は2記載の蓋材用包装用フィルム。
- 請求項1~3のいずれか一項に記載の蓋材用包装用フィルムを折り返して開封する蓋材として用いた蓋を有する包装容器。
