Formulated with premium organic Phthalocyanine Green G pigments and inorganic metal oxides, guaranteeing non-degrading color fastness even under extreme thermal processing conditions.
In modern industrial plastics processing, achieving exact chromatic consistency while maintaining structural polymer integrity is a critical benchmark for tier-one converters. China Green PE Masterbatch Factory & Supplier solutions represent the pinnacle of high-shear twin-screw compounding, where organic and inorganic pigments are homogeneously encapsulated into a virgin Polyethylene (PE) carrier resin matrix.
Key Engineering Insight: Optimal masterbatch performance depends on matching the Melt Flow Index (MFI) of the masterbatch carrier with the target base polymer. If the carrier MFI is improperly tuned, phase separation occurs, leading to streaks, pinholes, and reduced tensile strength in blown films and molded parts.
The primary role of a polyethylene masterbatch carrier is to encapsulate pigment micro-particles—typically ranging from 0.05 to 0.5 microns in primary particle size—and deliver them uniformly throughout the melt stream during extrusion or injection molding. At Changzhou Jiazhou Plastic Products Co., Ltd., our proprietary compounding line utilizes co-rotating twin-screw extruders featuring customized L/D (Length-to-Diameter) ratios of 44:1 or 48:1. This extended residence time under controlled shear stress breaks down pigment agglomerates into primary particles, eliminating surface defects in thin-gauge films down to 10 microns.
Green masterbatches primarily utilize C.I. Pigment Green 7 (Copper Phthalocyanine Green) and C.I. Pigment Green 36 (Chlorinated/Brominated Phthalocyanine Green). These organic pigments exhibit exceptional chemical inertness, resisting migration into food products, fats, and solvents. For applications requiring extreme heat resistance above 300°C—such as thick-walled HDPE pipe extrusion—inorganic Chrome Oxide Green (C.I. Pigment Green 17) is incorporated to prevent thermal degradation and chemical leaching.

International corporate buyers face strict regulatory mandates regarding hazardous substances in consumer packaging and industrial plastic goods. Changzhou Jiazhou Plastic Products Co., Ltd. enforces a zero-compromise compliance framework:
Our Green PE Masterbatch products undergo routine third-party testing via SGS and Intertek. Formulations strictly comply with European Union REACH Regulations (EC 1907/2006), verifying the absence of SVHC (Substances of Very High Concern). Furthermore, products satisfy RoHS Directive 2011/65/EU & (EU) 2015/863 restricting heavy metals such as Lead (Pb), Cadmium (Cd), Mercury (Hg), and Hexavalent Chromium (Cr VI).
The plastics industry is undergoing a paradigm shift toward circular economy principles. As a leading masterbatch supplier, Jiazhou is at the forefront of sustainable formulation advancements:
We now produce specialized masterbatches utilizing Bio-based Polyethylene (Bio-PE) derived from sugarcane ethanol, reducing net carbon footprints by up to 70% compared to fossil-based polymers. Additionally, for recycling facilities processing Post-Consumer Recycled (PCR) HDPE and LDPE, our green masterbatches incorporate anti-oxidant additives and heat stabilizers that neutralize resin degradation, restoring color brilliance and tensile strength in recycled plastic products.
Tailored masterbatch formulations optimized for specific plastic processing methods and end-use environments.
Engineered for agricultural greenhouse films, silage covers, shopping bags, and heavy-duty shipping sacks. Formulations deliver high opacity, UV protection, non-tearing stretch dynamics, and uniform coverage down to 12-micron film thickness.
