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.

Methods and apparatus for prilling are provided which include dynamically controlling the pressure at the prill head for increased control over prill quality and size distribution. In one embodiment, the pressure of a headspace above a volume of liquid or slurry is regulated to maintain a more precise control of the pressure of the liquid or slurry at the prill head. In another embodiment, an axial upflow device is used to maintain a more precise control of the pressure of the liquid or slurry at the prill head.
