LDPE Air Ring Single and Dual Lips
문제 현상
The LLDPE bubble is unstable with a single-lip air ring, with frequent film breakage making speed increase impossible.
원인 분석
A single-lip air ring is sufficient for LDPE bubble stability; LLDPE's soft characteristic during stretching makes bubble stability poor, requiring a dual-lip air ring to provide stronger cooling and support.
해결 방법
①Equip LLDPE with a dual-lip air ring to stabilize the bubble; ②Internal cooling IBC further improves stability; ③Dual-lip air rings are standard for high-output lines; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
핵심 요약
Air ring selection upgrades with the material; single lip is enough for LDPE, LLDPE must have dual lips plus internal cooling; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
