Description
例えば、充填食品が豆腐である場合、容器に豆乳と凝固剤を投入した豆腐材料を充填して密封し、豆腐材料を充填した容器を60~100度で加熱することにより、充填豆腐を製造している(例えば、特許文献1参照)。
この特許文献3に記載されている技術を特許文献2に記載された紙容器材料の最内層に適用すれば、紙容器の内面と食品との身離れ性が良くなり、紙容器から食品を容易に取り出せることになる。
図1は本発明に係る充填食品用紙容器を形成する容器材料の積層構造の一例を示す説明図である。
先ず、紙基材層(B層)の外面に熱可塑性樹脂層(A層)をラミネートして積層させる。
熱可塑性樹脂層(F層)、熱可塑性樹脂層(G層)、熱可塑性樹脂層(H層)の積層にあっては、熱可塑性樹脂層(F層)、熱可塑性樹脂層(G層)、熱可塑性樹脂層(H層)の3層フィルムを熱可塑性樹脂層(I層)の上にラミネートして積層してもよく、また、熱可塑性樹脂層(F層)、熱可塑性樹脂層(G層)、熱可塑性樹脂層(H層)の素材同士を共押出しにより熱可塑性樹脂層(I層)の上にラミネートして積層するようにしてもよい。
Claims (2)
- 外面側から内面側にかけて、ポリエチレン樹脂を主成分とする熱可塑性樹脂層(A層)、紙基材層(B層)、ポリエチレン樹脂を主成分とする熱可塑性樹脂層(C層)、バリア層(D層)、エチレン・メタクリル酸共重合樹脂を主成分とする接着層(E層)、ポリエチレン樹脂を主成分とする熱可塑性樹脂層(I層)、ポリエチレン樹脂を主成分とする熱可塑性樹脂層(F層)、ポリエチレン樹脂とポリプロピレン樹脂を混合した熱可塑性樹脂層(G層)、ポリオレフィン系樹脂に多価アルコールもしくはその誘導体およびポリオキシエチレン誘導体から選ばれる配合剤を添加した熱可塑性樹脂層(H層)を備えた容器材料からなり、
前記エチレン・メタクリル酸共重合樹脂を主成分とする接着層(E層)と前記ポリエチレン樹脂を主成分とする熱可塑性樹脂層(I層)は素材同士が共押出しにより積層状態に形成されたものであることを特徴とする充填食品用紙容器。 - 前記エチレン・メタクリル酸共重合樹脂を主成分とする接着層(E層)と前記ポリエチレン樹脂を主成分とする熱可塑性樹脂層(I層)の共押出しがTダイ法によるものであることを特徴とする請求項1に記載の充填食品用紙容器。
