Description
なお、ポリプロピレン系樹脂とは、プロピレン単独のみならず、プロピレンとα−オレフィンとの共重合体樹脂をも含むものとする。
この場合、外蓋材のポリエチレン系フィルム層と内蓋材のポリプロピレン系フィルム層との接着強度よりも容体とヒートシール性樹脂層との接着強度の方を高くする必要があるので、使用するヒートシール性樹脂の種類やシール条件等を適宜選択する必要がある。
試料:長さ200mm×幅15mm
試験方法:T型剥離試験(試料を100mm/分の速度でT字角度で剥離)
(1) 外蓋材
(2) 内蓋材
(3) 不連続切れ目線
(4) 部分開口予定部
(5) 外蓋材の基材層
(6) 溶融押出しによる低密度ポリエチレンフイルム層
Claims (3)
- 外蓋材と内蓋材とが積層されてなり、内蓋材がポリプロピレン系フィルム層から形成され、かつこの内蓋材に不連続切れ目線で囲まれた部分開口予定部または部分開口部が設けられ、外蓋材の基材層下面に内蓋材のポリプロピレン系フィルム層と界面剥離可能な溶融押出しによる低密度ポリエチレンフィルム層が設けられているホット飲料容器の蓋用蓋材。
- 内蓋材のポリプロピレン系フィルム層の下面に熱封緘性樹脂層が形成されている請求項1記載のホット飲料容器の蓋用蓋材。
- 外蓋材の低密度ポリエチレンフィルム層と内蓋材のポリプロピレン系フィルム層とのラミネート強度が5〜10N/15mmである請求項1または2記載のホット飲料容器の蓋用蓋材。
