Abstract
Description
ヒートシール可能な板紙であって、
- 第1の面および第2の面を含む板紙基材、
- 板紙基材の第1の面上に配置された第1の分散液コーティング層、および
- 第1の分散液コーティング層上に配置された第2の分散液コーティング層を含み、
第1の分散液コーティング層がラテックスおよび顔料を含み、第2の分散液コーティング層がポリオレフィンを含む、ヒートシール可能な板紙。
いくつかの実施形態では、板紙は以下の特性を有する:
- 5%以上、好ましくは6%以上もしくは7%以上の、ISO1924-2に従う引張強度によって測定された破断点伸び(CD)、および/または
- 10g/m2以下、好ましくは5g/m2以下の、SCAN試験P12:64に従って測定された吸水率(COBB600)。
吸水率は、板紙のコーティングされた第1の面上で、すなわち、それから形成された包装の裏面/内面を形成する面の上で測定される。
ヒートシール可能な板紙を製造する方法であって、
- 第1の面および第2の面を含む板紙基材を提供するステップ、
- 板紙基材の第1の面上に第1の分散液コーティング層を適用するステップ、
- 第1の分散液コーティング層上に第2の分散液コーティング層を適用するステップ、および
- 任意選択で、板紙基材の第2の面上に第3の分散液コーティング層を適用するステップを含み、
第1の分散液コーティング層がラテックスおよび顔料を含み、第2の分散液コーティング層がポリオレフィンを含む、ヒートシール可能な板紙を製造する方法。
図1は、本発明の一実施形態によるヒートシール可能な板紙の概略図である。
図2は、本発明の別の実施形態によるヒートシール可能な板紙の概略図である。
本発明の包装材料を評価するために、ロッドコーターを使用する実験室規模の試験で、本発明に従って製造された包装材料のバリア特性、破断点伸びおよび静摩擦係数を評価する一連の試験を実施した。
