Description
しかし、PLA樹脂系の接着剤を使用する方法は、紙カップの製造手順のヒートシール工程(縁部接合工程)の前段に、接着剤の塗布という工程を付加しなければならない点で、必ずしも称揚できない。
しかして、本発明の目的は、カップ胴部の接合に接着剤が全く使用されておらず、当該部分の接合が、加熱圧接で完遂されている紙カップを提供することにある。
100重量部のポリ乳酸樹脂に、0.6重量部の硫酸バリウムを配合して混練物を用意した。次に、押し出しラミネート機を用いてカップ用原紙(270g/m2)の片面に、混練物Aを厚さ20μmでラミネートすることで片面PLAラミネート紙を得た。
この片面PLAラミネート紙を通常の紙カップ製造装置に供給して紙カップAを製造した。
100重量部のポリ乳酸樹脂に、0.8重量部の硫酸バリウムを配合して混練物を用意した。次に、押し出しラミネート機を用いてカップ用原紙(270g/m2)の片面に、混練物Bを厚さ18μmでラミネートすることで片面PLAラミネート紙を得た。
この片面PLAラミネート紙を実施例1と同じ紙カップ製造装置に供給して紙カップBを製造した。
カップ用原紙(210g/m2)の片面に、ポリエチレン(低密度ポリエチレン)を厚さ15μmでラミネートして得た片面PEラミネート紙を用い、実施例1と同じ紙カップ製造装置に供給して紙カップXを製造した。
硫酸バリウムの配合を省いた以外は実施例1と全く同様にして片面PLAラミネート紙を得た。この片面PLAラミネート紙を実施例1と同じ紙カップ製造装置に供給して紙カップYを製造した。
Claims (3)
- 紙層と,硫酸バリウム又は沈降性硫酸バリウムを配合したポリ乳酸樹脂を,前記紙層の片面にラミネートして得たポリ乳酸樹脂層とを有する片面ポリ乳酸ラミネート紙をカップ材料とし,
前記片面ポリ乳酸ラミネート紙の一端の前記紙層に前記片面ポリ乳酸ラミネート紙の他端の前記ポリ乳酸樹脂層を加熱圧接することで成型されたカップ胴部を備える,
紙カップ。 - 紙の片面への上記ポリ乳酸樹脂のラミネート加工が,押し出しラミネートである請求項1記載の紙カップ。
- 硫酸バリウム又は沈降性硫酸バリウムの配合割合が,ポリ乳酸樹脂の固形分100重量部当たり,0.5〜3重量部の範囲で選ばれる請求項1記載の紙カップ。
