Blown‑Film Processing
‑ Processing temperature: general blown‑film temperature range 160‑220℃; fine‑tune according to low‑MFR characteristic and actual equipment. Excessively high temperature causes resin degradation and brittle film; insufficient temperature leads to poor plasticization. ‑ Screw configuration: higher driving power and melt pressure are required for this low‑melt‑flow grade. ‑ Blow‑up ratio: key process parameter, ratio of bubble diameter to die annular diameter. Typical range 2‑4. Higher blow‑up ratio improves transverse strength yet may cause bubble instability and film wrinkles. ‑ Draw ratio: ratio of film take‑up speed to annular extrudate speed. Higher draw ratio enhances longitudinal tensile strength. ‑ Cooling: sufficient cooling is required; well‑performed die cooling system ensures stable film forming.
