Description
示差走査熱量測定(DSC)は、半結晶性ポリマーの溶融及び結晶化を試験するために使用され得る一般的な技術である。DSC測定の一般原理及びDSCの半結晶性ポリマーの研究への応用は、標準的なテキスト(例えば、E.A.Turi,ed.,Thermal Characterization of Polymeric Materials,Academic Press,1981)に記載されている。Tmeは溶融が終了する温度を意味する。Tmaxはピーク溶融温度を意味する。
この実施例では、様々な量のLLDPEを有する一連の剥離可能なシール層を表1に示す組成物で調製する。
フィルムに対するヒートシール測定は、ASTM F−88(Technique A)に従って市販の引張試験機で実施される。ヒートシール試験は、軟質バリア材におけるシールの強度(シール強度)のゲージである。それはシールを含有する材料の試験ストリップを分離するのに必要とされる力を測定することによってこれを行い、試料破損のモードを特定する。シール強度は、開封力及びパッケージの全体性に関連する。切断の前に、ASTM D−618(Procedure A)に従って、23℃(±2℃)及び50%(±5%)R.H.(相対湿度)で最低40時間、フィルムをコンディショニングする。次いで、シートを、3層共押出された積層フィルムから、おおよそ11インチの長さ及びおおよそ8.5インチの幅に機械方向に切断する。以下の条件下で、ある温度範囲にわたって、Kopp Heat Sealerで機械方向に交差してシートをヒートシールする。
シーリング圧力:0.275N/mm2
シーリングドウェル時間:0.5秒
温度範囲は、ホットタック範囲(すなわち、少なくとも最小のホットタックシールが達成され、かつバーンスルー温度の前の温度範囲)によっておおおよそ与えられる。
フィルムに対するホットタック測定は、ASTM F−1921(Method B)に従ってEnepay市販試験機を使用して実施される。試験の前に、ASTM D−618(Procedure A)に従って、23℃及び50%R.H.で最低40時間、フィルムをコンディショニングする。ホットタック試験は、シールが完全に冷却する機会を有する前に、材料をパウチまたは袋に充填することをシミュレートする。
試料幅:25.4mm(1.0in)
シーリング圧力:0.275N/mm2
シーリングドウェル時間:0.5秒
遅延時間:0.18秒
剥離速度:200mm/秒
この実施例では、実施例1からの比較組成物A、本発明の組成物2、及び本発明の組成物4を調製し、再度測定する。この実施例はまた、以下の通りの本発明の組成物5及び6を評価した。
