Engineered with 100% virgin polyethylene carriers and food-safe inorganic/organic pigments. Optimized for high-speed blown film, injection molding, and complex profile extrusion.
In modern food packaging engineering, the transition from basic colorants to certified, migration-compliant polymer additives is governed by strict global safety directives. As a premier custom FDA food certified PE masterbatch manufacturer, Changzhou Jiazhou Plastic Products Co., Ltd. addresses the stringent demands of international food packaging supply chains.
Specifies the exact purity metrics and extraction limits for polyethylene polymers intended for direct and indirect food contact. Our PE masterbatch formulations utilize exclusively approved virgin LLDPE/HDPE resin matrices with certified low extractable fraction profiles under N-hexane and xylene solvents.
Aligns with European Union Regulation (EU) No 10/2011 on plastic materials intended to come into contact with food. Complete verification of Overall Migration Limits (OML) and Specific Migration Limits (SML) for heavy metals, primary aromatic amines (PAAs), and volatile organic compounds (VOCs).
Full compliance with Chinese National Food Safety Standards for food-contact plastic resins. Our production lines maintain strict traceability protocols ensuring batches pass rigorous sensory testing, potassium permanganate consumption, and heavy metal extraction challenges.
Standard industrial color masterbatches often rely on low-cost dispersants or unrefined pigment cakes that contain trace heavy metals (Lead, Cadmium, Hexavalent Chromium) or low-molecular-weight waxes. Under heat or acidic food contact, these low-molecular species migrate into the foodstuff. Jiazhou's custom FDA food certified PE masterbatch utilizes hyper-dispersed, ultra-high molecular weight organo-inorganic complexes bound within a narrow molecular weight distribution PE lattice, rendering migration technically non-detectable.
The operational success of food-grade masterbatch depends on matching carrier melt flow indices (MFI) to target sub-resins while enforcing zero-contamination processing environments.
