Abstract
A process is disclosed for forming blown film of a low strain hardening polymer, such as a low pressure polymerized-low density ethylene copolymer, including an improved film bubble expanding technique which permits high production rates to be achieved with good film bubble stability. Advantageously, most of the films produced by the process have a relatively high degree of film clarity.
