HDPE food contact
Problembeschreibung
HDPE food containers have odor, or the migration test fails
Ursachenanalyse
HDPE itself has good food contact safety, but additives and degradation products may migrate; the migration amount increases when in contact with high-temperature grease; misuse of non-food-grade grades leads to compliance failure
Lösung
①Select FDA-compliant grades for food contact; ②perform migration verification according to the use temperature and contact medium; ③obtain the supplier's compliance statement; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
HDPE is the main material for food packaging; grade compliance plus migration verification is the application prerequisite; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
