Explore our primary masterbatch grades manufactured specifically for high-speed blown film, non-woven extrusion, and injection molding applications.
In the global B2B flexible packaging and eco-friendly shopping bag sector, Polyethylene (PE) non-woven fabrics—specifically those manufactured via continuous spunbond and meltblown processes—demand exceptionally rigorous polymer masterbatch formulations. Unlike conventional injection molding or heavy-gauge sheet extrusion, non-woven fiber spinning forces molten polyolefin resin containing concentrated pigment through microscopic spinneret nozzles ranging from 0.15 mm to 0.6 mm in diameter. Any sub-optimal agglomeration of organic pigments or inorganic carrier additives immediately leads to continuous filament breakage, pressure spikes across melt pumps, and costly production line downtime.
As a primary China PE color masterbatch manufacturer with 16 years of polymer compound engineering experience, Changzhou Jiazhou Plastic Products Co., Ltd. specializes in synthesizing high-dispersion PE masterbatch specifically tailored for non-woven shopping bag production lines. By controlling key rheological metrics including Melt Flow Index (MFI) matching, filter pressure values (FPV < 1.5 bar/g), and ultra-fine sub-micron pigment grinding, our factory yields color masterbatch that ensures brilliant color opacity, maximum tensile strength retention, and zero spinneret head clogging during high-speed spinning (up to 600 m/min).
Our PE non-woven bag masterbatches utilize virgin carrier resins matching the exact melt flow index (MFI 15 to 40 g/10min) of the target non-woven polyolefin matrix, ensuring homogenous thermal blending without phase separation.
Pigment particles are subjected to multi-pass wet milling and triple-screw dispersive extruders, maintaining particle size under 1.5 microns to eliminate filament surface defects and micro-hole formation.
Formulated to resist thermal degradation up to 260°C – 280°C. Prevents shade alteration, gas-fading, and degradation of physical tensile elongation properties during high-temperature extrusion.
The structural integrity of a non-woven PE shopping bag depends upon continuous filament tenacity. When masterbatch is incorporated into the extruders, pigment agglomerates act as stress concentration points if not properly dispersed. Our factory implements high-shear twin-screw compounding combined with customized low-molecular-weight polyethylene dispersant waxes (PE wax) to coat individual pigment molecules during synthesis.
| Performance Parameter | Jiazhou Non-Woven Grade Masterbatch | Standard Commercial Masterbatch | Industrial Quality Impact |
|---|---|---|---|
| Pigment Dispersion (Particle Size) | < 1.2 Microns (D99) | 5.0 – 12.0 Microns | Zero spinneret hole blockage; seamless continuous filament spinning. |
| Filter Pressure Value (FPV) | < 0.8 bar/g (DIN EN 13900-5) | > 3.5 bar/g | Extends filter pack lifespan by 300%; reduces melt pressure surges. |
| Melt Flow Index (MFI @ 190°C/2.16kg) | Customized: 25 - 45 g/10min | Fixed: 5 - 10 g/10min | Eliminates polymer melt fracture and yarn necking during high-speed draft. |
| Heat Resistance Rating | 260°C – 280°C Continuous | 200°C – 220°C | Prevents color shifting and thermal degradation during thermal bonding/embossing. |
| Color Migration Stability | Grade 5 (ISO 105-X12 Anti-bleed) | Grade 3 (Slight Bleeding) | Prevents pigment transfer to stored retail items or heavy shopping bag loads. |
As illustrated above, optimizing the Filter Pressure Value (FPV) is essential for B2B procurement managers seeking to maximize factory throughput. Lower FPV directly translates into fewer screen pack changes on non-woven production lines, saving hundreds of labor hours annually and significantly reducing scrap rates during bag manufacture.
Global packaging regulations are shifting rapidly toward circular economy frameworks. Global enterprises in the European Union, North America, and Southeast Asia face stringent mandates regarding single-use plastics, requiring shopping bag manufacturers to transition toward Post-Consumer Recycled (PCR) polyolefins and bio-based carriers. Our technical team at Changzhou Jiazhou has developed advanced color solutions to address the inherent challenges of recycled plastic processing.
We supply specialized masterbatch carrier resins compatible with up to 100% Post-Consumer Recycled (PCR) PE/PP resins, masking yellowing effects and neutral color variances common in recycled feedstocks.
Fully compliant with EU REACH Annex XVII, RoHS 3.0, and FDA 21 CFR 177.1520 standards. Formulated without lead, cadmium, or diarylide pigments, ideal for grocery shopping bag applications.
High pigment loading design allows low let-down ratios (LDR of 1% to 3%), drastically lowering logistics volume and reducing energy consumption during extrusion compounding.
Selecting the right OEM/ODM masterbatch manufacturer requires evaluating scale stability, chemical procurement integration, and direct factory quality guarantees. Situated in Changzhou, Jiangsu Province—the epicenter of China's high-tech polymer extrusion hub—Changzhou Jiazhou Plastic Products Co., Ltd. operates a modernized 6,000m² manufacturing facility serving B2B clients in over 100 countries.
With 16 years of continuous R&D, our facility operates twin-screw high-torque extruders capable of annual outputs exceeding 15,000 metric tons. We maintain strict batch-to-batch consistency using Datacolor spectro-photometers, guaranteeing Delta E (ΔE) color variance under 0.5.
Direct strategic procurement with Sinopec, PetroChina, and top-tier global pigment suppliers allows us to bypass intermediary cost markups. Our streamlined production logistics deliver customized color matching samples within 48 hours and complete container load fulfillments within 15 days.
When evaluating masterbatch for non-woven shopping bag production, buyers must align technical properties with the end-use bag requirements. Below is our engineered application matrix detailing recommended let-down ratios (LDR) and functional additive additions for various shopping bag market sectors.
Recommended LDR: 2.0% – 4.0%
Requires high tensile strength and puncture resistance. Formulated with PE color masterbatch featuring slip additive synergy and high lightfastness (Blue Wool Scale 7-8) for outdoor reuse.
Recommended LDR: 1.5% – 3.0%
Focuses on visual vibrancy and high surface gloss. Metallic Gold and Silver PE masterbatches utilize ultra-fine mica/aluminum platelets surface-treated to eliminate nozzle clogs.

Addressing the critical engineering, rheological, and procurement questions raised by global non-woven bag manufacturers and plastic extrusion plants.
Standard masterbatches engineered for injection molding or thick film extrusion often contain larger pigment agglomerates (> 5-10 microns) and low MFI carriers. When processed through non-woven spinneret orifices (0.15–0.4 mm), these large particles quickly clog filter packs, cause frequent yarn breakage, and disrupt melt pressure. Non-woven grade masterbatch requires sub-micron dispersion and specialized melt-flow matching.
We employ triple-screw high-shear extrusion compounding combined with specialized low-viscosity dispersant systems. Every masterbatch batch undergoes strict Filter Pressure Value (FPV) testing per DIN EN 13900-5, guaranteeing an FPV below 0.8 bar/g. This guarantees uninterrupted high-speed filament spinning up to 600 meters per minute.
Depending on required color opacity and bag thickness (GSM), our high-concentration masterbatches operate effectively at an LDR of 1.0% to 3.0%. For intense hues or metallic effects (such as gold/silver), an LDR of 2.5% to 4.0% is recommended. Our technical lab can customize pigment concentrations to minimize your overall cost-per-ton.
Yes. Our organic and inorganic pigments are selected for thermal stability exceeding 260°C – 280°C. They do not discolor, sublime, or degrade during continuous hot-rolling, ultrasonic welding, or heat-sealing during shopping bag conversion.
Absolutely. All our non-toxic masterbatch formulations comply fully with EU REACH regulation (EC No 1907/2006), RoHS directives, and US FDA 21 CFR standards for plastics intended for food contact, making them 100% safe for supermarket grocery shopping bags.
Clients provide Pantone, RAL codes, or physical target samples. Our color R&D lab utilizes computer spectrophotometers to generate exact matches within 48 hours. Trial laboratory samples are extruded and spun into actual test non-woven swatches before full-scale container production.
