LDPE Storage and Transportation
Fenómeno del problema
Pellets agglomerate during storage, or film rolls block and cannot be used after storage
Análisis de la causa
LDPE pellets may agglomerate when stored in high-temperature environments; interlayer blocking occurs in film rolls when the slip agent is insufficient; storage temperature and stacking pressure are the main variables; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solución
① Store pellets in a cool place to prevent high-temperature agglomeration; ② film rolls contain sufficient antiblock agent; ③ store film rolls vertically to prevent pressure blocking; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusión clave
LDPE storage manages temperature and pressure; pellets prevent agglomeration and film rolls prevent blocking, each with its own countermeasures; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
