Information Gain Insight: Unlike generic masterbatch formulations that use low-cost recycled carriers causing melt fracture during high-speed blown film extrusion, Jiazhou's customized PE masterbatches utilize virgin Linear Low-Density Polyethylene (LLDPE) carriers with identical Melt Flow Indexes (MFI) to your base virgin or recycled resin. This eliminates interfacial tension, reducing die build-up by up to 65% and preventing film bubble oscillation.
Tailored optical, thermal, and pest-repellent functionalities for specialized co-extrusion agricultural mulch film lines.
Formulated with fine particle size P-type carbon black. Blocks 99.9% of Photosynthetically Active Radiation (PAR, 400-700nm) to completely eradicate weed germination without herbicides, preserving soil moisture and nitrogen levels.
Designed for 3-layer co-extrusion blown film lines. The outer silver layer reflects UV rays to repel winged aphids and thrips while maintaining cooler root temperatures; the inner black layer suppresses weeds and blocks root-zone solar thermal stress.
Integrates specialized organic pigments and non-migratory surfactant additives. Controls NIR (Near Infrared) heat transfer while providing long-lasting anti-drip and anti-fog performance inside greenhouse tunnels and crop covers.
Strategic location, twin-screw extrusion automation, and strict ISO-certified quality assurance driving global supply chain reliability.
Located in the plastic manufacturing hub of Changzhou, Jiangsu, Changzhou Jiazhou Plastic Products Co., Ltd. operates a 6,000m² state-of-the-art production facility equipped with multi-zone high-torque twin-screw extruders. We maintain direct strategic partnerships with Tier-1 global pigment and carbon black manufacturers.
By controlling the surface treatment chemistry of raw pigments (silane and titanate coupling agents), we achieve ultra-high pigment loading without compromising the rheological flow of the PE matrix. This offers global buyers a cost reduction of 15%–25% compared to European or American suppliers, with zero compromise on tensile elongation at break or melt strength.
Every masterbatch batch undergoes rigorous quality control: X-ray fluorescence (XRF) elemental testing, computerized color spectrophotometry, Melt Flow Index (MFI) verification, and laboratory-scale blown film extrusion to inspect pinholes and dispersion specs before container loading.
With export documentation completed in-house and a guaranteed 15-day production lead time, Jiazhou provides seamless OEM and private label services to over 100 countries across North America, South America, Southeast Asia, the Middle East, and Europe.
Strategic solutions for bio-degradable carrier integration, pesticide chemical resistance, and ultra-thin film processing stability.
The Challenge: Conventional PE mulch leaves toxic soil residues, prompting strict soil protection regulations worldwide.
Jiazhou Solution: We supply specialized PBAT/PLA bio-masterbatch carriers loaded with organic pigments and natural inorganic UV blockers, enabling fully compostable soil degradation without heavy metals.
The Challenge: Pesticides, acidic soils, and sulfur fumigation deactivate standard HALS light stabilizers, destroying film strength.
Jiazhou Solution: Incorporating non-basic NOR-HALS additives and active acid scavengers into masterbatch formulas to withstand up to 3000 ppm sulfur exposure.
The Challenge: Post-consumer recycled (PCR) resin contains impurities and variable MFI, causing melt fractures and dull colors.
Jiazhou Solution: Formulated with processing aids (PPA) and targeted antioxidant packages to homogenize PCR viscosity and restore physical elasticity during extrusion.
A systematic technical trial, color matching, and supply chain verification workflow for industrial film producers.
Buyer provides target polymer resin specs (LDPE/LLDPE/mLLDPE) and extruder screw L/D ratio to determine carrier viscosity.
Target color or optical performance (PAR transmittance, Delta E < 0.5) matched in our R&D laboratory via spectral analysis.
Sample batches (100kg-500kg) are run on pilot blown film lines to verify filter pressure (FPV) and bubble stability.
High-volume twin-screw compounding with automated pellet screening, moisture checks (<0.08%), and ISO certification.
