Abstract

Compositions of polyamide resins containing a low level of polyamide 66 comonomer are provided, which are useful in producing blown films. A method of forming a blown film includes: extruding a polyamide copolymer to form a polyamide film. The polyamide copolymer is formed from a mixture of caprolactam and hexamethylenediamine adipate where the caprolactam comprises from 85 mol. % to 99 mol. % of the total moles of caprolactam and hexamethylenediamine adipate.
