Excessive migrants in PET food packaging
문제 현상
PET food packaging migrant test exceeds standard (total migration >10mg/dm²), not complying with food contact regulations.
원인 분석
High low-molecular oligomer content in raw material, processing temperature too high producing degradation products, high additive migration.
해결 방법
Select food-grade PET (low oligomer); reduce processing temperature; control additive types and dosages; strictly control recycled material.
핵심 요약
PET food packaging compliance involves comprehensive control of raw materials, process, and additives.
