Explore our top-tier color and filler masterbatches engineered for maximum pigment dispersion, thermal endurance up to 260°C–300°C, and melt consistency.
Understanding the molecular dynamics, melt index matching, and structural strain requirements for high-speed raffia extrusion lines.
In modern polypropylene (PP) and polyethylene (PE) woven sack manufacturing, flat tape extrusion operates under extreme mechanical shear and orientation draw ratios (typically ranging from 1:4 to 1:7.5). As extruded film strips pass through heating ovens and orientation godets at line speeds exceeding 500 meters per minute, any microscopic agglomeration of inorganic pigment or carrier resin mismatch causes catastrophic strand snapping, micro-fibrillation, or splitting.
Our PE Masterbatch for Woven Bag Drawing is engineered with narrow molecular weight distribution (MWD) Linear Low-Density Polyethylene (LLDPE) carriers, delivering uniform melt fluidity and zero melt fracture during high-speed stretching.
A critical benchmark for drawing masterbatches is the Filter Pressure Value (FPV), measured in bar/g according to EN 13900-5. Standard commercial colorants frequently exceed 2.5 bar/g, clogging melt screen packs (100–150 mesh) and forcing frequent extruder shutdowns.
By utilizing sub-micron pigment dispersion and multi-stage twin-screw shearing techniques, Jiazhou’s woven bag drawing masterbatch guarantees an ultra-low FPV under 0.4 bar/g. This prolongs screen filter lifespan up to 300%, maintains stable die backpressure, and eliminates gauge variation across stretched tapes.
| Performance Parameter | Standard Commercial Masterbatch | Jiazhou Drawing PE Masterbatch | Industrial Benefit |
|---|---|---|---|
| Carrier Resin Grade | Recycled or Broad MWD LDPE | Prime Virgin LLDPE / Metallocene PE Blend | Eliminates structural weak points during stretching |
| Filter Pressure Value (FPV) | 1.8 – 3.5 bar/g | < 0.4 bar/g | Prevents screen pack clogging & line stoppage |
| Pigment Particle Size | 2.5 – 5.0 microns | < 0.5 microns (Micronized) | Maximized color yield & zero filament breakage |
| Thermal Stability Rating | 220°C – 240°C | 260°C – 300°C | Zero thermal degradation or off-gassing at high heat |
| Tape Tenacity Retention | 82% – 88% | 96% – 99.5% | Exceeds ISO 21898 standards for FIBC heavy load sacks |
A look inside our multi-stage extrusion technology, pigment wetting agents, and thermal stabilizer complexes.
We incorporate metallocene-catalyzed polyethylene (mPE) as a secondary carrier modifier. mPE offers exceptionally low molecular weight distribution and precise viscosity matching to standard host PP/PE resins, reducing interfacial tension between pigment clusters and matrix polymer during high-ratio drawing.
Uncontrolled longitudinal splitting is the leading defect in woven sack tape drawing. Our proprietary formulation includes specialized hyper-dispersants and processing aids that encapsulate organic and inorganic pigments, mitigating internal stress concentrations and maintaining high transverse film toughness.
Woven bags deployed in outdoor agricultural storage or maritime shipping face intense solar radiation. We integrate high-molecular-weight Hindered Amine Light Stabilizers (HALS) and primary/secondary antioxidants (Irganox 1010 / Irgafos 168 equivalent), guaranteeing lightfastness ratings of 7–8 on the Blue Wool Scale.
Delivering continuous supply chain reliability to over 100 countries across packaging, agriculture, and construction sectors.
The worldwide Flexible Intermediate Bulk Container (FIBC) and industrial woven sack market is expanding rapidly, driven by agricultural exports, bulk chemical logistics, and infrastructure geotextiles. Converting mills in South East Asia, the Middle East, South America, and Europe require masterbatches that sustain continuous extrusion without inducing die build-up or filament breakage during high-speed weaving on circular looms.
Modern B2B buyers must navigate complex environmental guidelines. Our high-concentration PE masterbatches strictly adhere to EU REACH Regulation (EC) No 1907/2006, RoHS 3 Directive 2015/863, FDA 21 CFR 177.1520 for food contact packaging, and heavy-metal-free standards (EN 71-3).
Headquartered in Changzhou, Jiangsu Province, Changzhou Jiazhou Plastic Products Co., Ltd. represents the cutting edge of Chinese masterbatch manufacturing.
Operating multiple high-speed, co-rotating twin-screw extruder lines equipped with loss-in-weight gravimetric dosing systems. Our automated production line ensures pigment loading accuracy within ±0.2%, eliminating batch-to-batch color shifts and density fluctuations.
Strategically located in the Yangtze River Delta industrial belt near Shanghai and Ningbo deep-water ports. We maintain a raw material safety stock of prime PE resins and high-purity pigments, ensuring seamless 15-day order turnaround for international FCL and LCL ocean shipments.
Every batch undergoes rigorous quality assurance inside our ISO-certified lab: X-Rite Datacolor spectrophotometer analysis, melt flow index testing (ASTM D1238), moisture content analysis (< 0.05%), and blown film microscopic gel inspection before packaging release.

Pioneering sustainable carrier formulations, post-consumer recycled (PCR) resin integration, and ultra-thin raffia tape engineering.
As global sustainability initiatives accelerate, woven bag converters are increasing the ratio of Post-Consumer Recycled (PCR) and Post-Industrial Recycled (PIR) polyolefins in their extruders. Recycled polymers frequently suffer from wide melt flow variability, thermal history degradation, and odor issues. Jiazhou’s advanced R&D roadmap introduces specialized compatibilizing masterbatches that repair polymer chains, stabilize melt viscosity, and restore optical brilliance when using recycled resin streams.
The industrial packaging market is shifting toward light-weighting to reduce material cost and carbon footprints. Conventional colorants fail when drawing ultra-thin tapes below 20 Tex due to pigment agglomerates breaching tape thickness. Jiazhou is deploying sub-micron nano-pigment surface coating tech, establishing high color density at let-down ratios as low as 1.0%–1.5%, enabling light-weighting without sacrificing opacity or mechanical strength.
