High film breakage rate of PLA biaxially stretched film
Problembeschreibung
Biaxially stretched PLA film breaks frequently.
Ursachenanalyse
PLA has limited extensibility, and excessive stretching exceeds the limit.
Lösung
Control draw ratio (longitudinal 2-3, transverse 2-3); optimize stretching temperature.
Wichtigste Erkenntnis
PLA biaxial stretching film breakage rate is higher than traditional polyester.
