Abstract:Perturbation analysis, which has never been applied to film blowing, was used to explore the effect of system disturbances on the process. Results showed that perturbations related to heat transfer and inflation pressure were more significant than the effect of die swell. In addition, crystallinity is shown to have a stabilizing effect on the system, with more crystallinity dampening the effect of perturbations. Stability diagrams for each material and model show reasonable results, with higher blow-up ratios becoming unstable for all draw ratios.
