COPOLYAMIDE FILM FOR PACKAGING

PURPOSE:To provide a copolyamide film having improved blocking resistance, by blending a bisamide with a copolyamide film. CONSTITUTION:A copolyamide film for packaging is obtd. by blending 0.1-0.5 pts.wt. bisamide of formula I or II with 100pts.wt. copolyamide. In the formulas, R is alkylene, aryle...

Zusammenfassung:	PURPOSE:To provide a copolyamide film having improved blocking resistance, by blending a bisamide with a copolyamide film. CONSTITUTION:A copolyamide film for packaging is obtd. by blending 0.1-0.5 pts.wt. bisamide of formula I or II with 100pts.wt. copolyamide. In the formulas, R is alkylene, arylene, arylenedialkylene; R , R are each alkyl, aryl, aralkyl, cycloalkyl; R , R are each H, alkyl, aryl, aralkyl, cycloalkyl. Examples of the copolyamide are nylon 6/66, nylon 6/610 and nylon 6/66/12. Examples of the bisamides of formula I are N,N'-methylenebisstearamide and N,N'- ethylenebisstearamide. An example of the bisamide of formula II is dioctadecyl dibasic acid amide.
