Engineered with specialized carrier resins to guarantee maximum dispersion, zero phase separation, and enhanced mechanical integrity in recycled polyethylene compounds.
Post-Consumer Recycled (PCR) and Post-Industrial Recycled (PIR) Polyethylene pose significant compounding hurdles due to thermal history degradation, cross-contamination, melt flow index (MFI) variance, and residual odor.
Recycled PE often contains traces of Polypropylene (PP), PET, or EVA. Our specialized Masterbatch utilizes Maleic Anhydride Grafted Polyethylene (PE-g-MAH) coupled with reactive functional surfactants. This lowers interfacial tension between immiscible polymer phases, preventing phase separation, mechanical brittleness, and surface delamination during high-speed extrusion.
PCR feedstocks suffer from severe batch-to-batch MFI fluctuations (ranging from MFI 0.2 to 8.0 g/10min). Our custom formulations incorporate narrow molecular weight distribution (MWD) carrier resins combined with rheology control agents. This stabilizes melt tension, reduces melt fracture (sharkskin effect) in blown film, and ensures uniform mold filling in injection processes.
Regrind materials frequently possess an inherent grey/yellow tint and residual volatile organic compounds (VOCs). We integrate micro-encapsulated inorganic absorbers (molecular sieves) alongside high-chroma, high-heat-resistant organic pigments to neutralize yellowing, mask background color variances, and absorb processing odors up to 260°C.
Understanding the fundamental technical metrics that distinguish general-purpose colorants from engineered recycled-grade masterbatches.

Located in the heart of China's advanced manufacturing corridor, Changzhou Jiazhou combines 16 years of polymer compounding experience with scalable, cost-optimized production capabilities.
Our 6,000 m² factory houses state-of-the-art co-rotating twin-screw extruders featuring high-vacuum multi-stage de-volatilization zones. This allows deep degasification of volatile contaminants while compounding colorants directly into sensitive PCR substrates.
By leveraging robust raw material procurement networks across China’s chemical hubs and optimizing pigment concentration up to 50%-70% loading, we deliver significant unit-cost savings to global buyers without compromising optical or mechanical performance.
Every production run undergoes rigorous spectro-photometric testing (Datacolor 800), melt flow index analysis (ASTM D1238), moisture titration, and blown film filter press test (FPV) to guarantee batch-to-batch color delta-E < 0.5 and zero nozzle blockage.
As global packaging regulations move rapidly toward compulsory recycled plastic content, procurement managers require compliant, traceable, and performance-backed masterbatch suppliers.
With the European Union mandatory packaging waste directives requiring up to 30% recycled content by 2030, our PCR-compatible PE masterbatch enables converter plants to maintain high line speeds, zero burst rates, and vibrant branding colors while complying with Extended Producer Responsibility (EPR) mandates.
All Jiazhou products are fully documented with SVHC screening under REACH, heavy metal test reports under RoHS 2.0, and halogen-free certifications necessary for European and North American market clearance.
Using our high-concentration masterbatches with recycled carriers allows brand owners to directly lower their Scope 3 greenhouse gas emissions. By replacing virgin polymer carriers with certified post-industrial or post-consumer PE bases, converter operations lower total life-cycle carbon intensity per ton of finished plastic goods.

Stay ahead of market shifts with next-generation masterbatch innovations currently in development at Changzhou Jiazhou.
As recycled plastic feeds exhibit fluctuating baseline shades, traditional fixed color formulas often result in batch off-tones. Jiazhou is pioneering spectrophotometer AI matching that dynamically adjusts pigment ratio masterbatch additions based on incoming regrind color values, keeping finished products precisely within target color corridors.
Moving beyond standard fossil-fuel resins, the future of masterbatch manufacturing lies in bio-based Polyethylene (Bio-PE derived from sugarcane) and chemically recycled post-consumer resins.
