LLDPE corona decay
Fenómeno del problema
Printing adhesion of LLDPE film decreases with storage
Análisis de la causa
Corona treatment level decays over time; when troubleshooting on site, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solución
Re-measure dyne value before printing; print as soon as possible; re-corona when necessary; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Conclusión clave
Manage corona effect by aging; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
