Abstract
Description
(a)50〜76重量%のホモポリプロピレン;
(b)2モル%〜10モル%のエチレン由来ユニットを有する12重量%〜25重量%のランダムコポリマーポリプロピレン;および
(c)10重量%〜25重量%のエチレン由来ユニットを有する12重量%〜25重量%のプロピレン−エチレンコポリマー。
(i)0.1g/10分〜4.0g/10分のMFR;
(ii)15N/15mm〜30N/15mmの密封強度
(iii)少なくとも15N/15mmの密封強度に対して165℃の密封開始温度。
実施例1:測定方法
(6.1)試料の調製:平らなレトルト可能なパウチを用いて、本明細書に開示するポリプロピレンフィルムの汚染特性について密封を評価した。パウチは、180℃、圧力2バール、保持時間1秒の恒温密封棒を有する高温密封バー機器を用いて、3辺密封包装パウチの形態で調製した。3辺密封包装パウチの内径は12.0cm×15.0cmであった。3辺密封包装パウチは、それぞれ200mLの食品模倣物を含む小型のバッグを形成していた。パウチの残りの辺を密封してレトルト可能なパウチを閉じ、それぞれの充填パウチ内の容積およびヘッドスペースを制御する固定位置にした。
出発材料はすべて市販されていた。
