HDPE film ultra-thin film breakage
Sorun Belirtisi
Frequent film breakage occurs in the production of ultra-thin film below 10μm, and the yield is low.
Neden Analizi
Ultra-thin film has extremely high requirements for melt strength and uniformity; tiny gels and thickness fluctuations are magnified into breakage points.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Çözüm
①Add nano nucleating agent to improve melt strength; ②adopt gradient cooling technology; ③strengthen filtration to reduce gels; ④lower the blow-up ratio and operate conservatively.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
Ultra-thin film is the high-end field of film blowing technology; material modification and fine cooling must be used together to achieve stable production.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
