PLA film brittle tearing
Sorun Belirtisi
PLA film has poor tensile and tear properties.
Neden Analizi
PLA's inherent brittleness makes the film poorly ductile; the crystalline state also affects toughness.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Çözüm
① Add plasticizers to improve flexibility; ② blend with PBSA/PHB etc.; ③ optimize the biaxial stretching process; ④ control crystallinity.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
PLA film relies on plasticization and blending to improve toughness; bio-based toughening agents maintain degradability.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
