Product Intelligence
High Concentration Filled Black Masterbatch for Film & Extrusion
Engineered for blown film lines that demand consistent deep-black coverage without compromising tensile integrity. E30 combines a 31% carbon black loading with calcium carbonate in a recycled PE carrier — giving film converters opaque blackness, a manageable melt flow, and a measurably lower virgin-material footprint in a single pellet.
Unlike diluted-concentration alternatives that require elevated dosage to reach full opacity, E30 achieves target blackness at 1–3% let-down ratio. That narrow range translates directly into cost control: purchasing teams can forecast raw-material spend without worrying about batch-to-batch dosage drift.

Product Highlights
Six Reasons Film Producers Specify E30
Coloration
Jet-Black at Low Add-On
A 31% carbon black load means you reach full visual opacity at just 1–3% dosage. There is no need to push let-down ratios higher to compensate for under-concentrated product, which keeps formulation costs predictable.
Rheology
High MFI for Smooth Film Extrusion
MFI exceeding 10 g/10 min at 190 °C/21.6 kg ensures the masterbatch merges readily into the host resin melt stream. Film lines running LDPE or LLDPE blends report consistent gauge without die-line artifacts related to poorly melted pigment agglomerates.
Filler Balance
CaCO₃ Extends Without Brittleness
The calcium carbonate filler component lowers the effective cost per ton of finished film without the stiffness penalty that coarser mineral fillers can introduce at elevated dosage. Ash content held below 32% keeps mechanical degradation minimal.
Circular Economy
Recycled PE Carrier
Using post-industrial recycled polyethylene as the carrier resin reduces demand for virgin feedstock in the masterbatch itself. For producers working toward recycled-content declarations in their packaging, this directly contributes to the material chain.
Moisture
Dry Pellets — Ready to Run
Moisture held below 0.50% eliminates the pre-drying step that high-moisture masterbatches require before extrusion. That means less energy consumption at the converter's site and shorter setup times during product changeovers.
Versatility
Tri-Process Compatibility
Qualified for blown film, pipe extrusion, and injection molding within a single grade. Procurement teams running mixed production lines can consolidate SKUs instead of maintaining separate masterbatch inventory for each downstream process.
End-Use Applications
Where E30 Is Used
The grade is optimized for applications where uniform black coloring, adequate film integrity, and cost-efficiency must coexist. Below are the primary downstream markets.
Garbage & Bin Liners
Flat and star-sealed black bin bags for municipal, commercial, and industrial waste collection.
Shopping Bags
Carrier bags and t-shirt bags for retail and grocery chains requiring opaque, robust black film.
Agricultural Mulch Film
Blown PE film for soil temperature control, weed suppression, and moisture retention in field crops.
Corrugated Pipe
Drainage and conduit pipes where black pigmentation provides UV protection and a consistent finish.
Industrial Packaging
Heavy-duty wrapping film and pallet liners for logistics, construction material, and chemical sectors.
Protective Sheeting
Construction protection films and geomembrane liners where opacity and tensile strength are critical.
Injection-Molded Parts
Housings, containers, and structural components where uniform black tone and low-moisture input matter.
UV-Barrier Wrap
Silage wrap and light-blocking storage film for agriculture and food processing logistics.
Processing Guide
Recommended Dosage by Process
The let-down ratio affects final color depth, film transparency, and production cost. These ranges represent factory-validated starting points. Fine-tuning to your specific resin, line speed, and finish requirements is recommended.
1–2%
Blown Film (Thin-Gauge)
For standard bin liners and shopping bags where full opacity is achieved at the lower range. Start at 1.5% and adjust based on JET blackness target.
2–3%
Blown Film (Heavy-Gauge) & Pipe
Thicker extrusion profiles may require the upper range to maintain consistent wall color. For corrugated drainage pipe, 2.5% is a common starting point.
1.5–2.5%
Injection Molding
Injection cycles with short shot times benefit from the high MFI of E30. For thin-wall molding, stay at the lower end to avoid potential plate-out at the gate.

From Raw Material to Pellet
How E30 Is Manufactured
E-LUCK operates an integrated production site in Huizhou, Guangdong. Every step from carbon black sourcing to final pellet packaging happens under one roof, giving the factory direct control over consistency and lead time.
01
Raw Material QC
Incoming carbon black and CaCO₃ tested for particle size, purity, and moisture before release to production.
02
Carrier Preparation
rPE carrier resin screened and conditioned. MFI verified to ensure carrier–pigment co-melt compatibility.
03
High-Shear Mixing
Carbon black and filler pre-dispersed at high shear to break agglomerates before entering the twin-screw extruder.
04
Twin-Screw Extrusion
Co-rotating extruder distributes pigment into the melt matrix. Temperature profile calibrated to E30 rheology.
05
QC & Packing
Finished pellets tested for MFI, moisture, ash, and color before being packed into 25 kg bags with batch labeling.
Sustainability
Closing the Loop on Plastic Colorant Production
By specifying rPE as the carrier, E30 keeps post-industrial polyethylene in active circulation rather than diverting it to landfill. For downstream producers with recycled-content targets in their product declarations, E30's carrier material is a documentable contribution toward those goals.

Manufacturer Advantage
Why Buyers Choose E-LUCK Direct
Sourcing from the factory rather than a distributor changes what you can ask for — and what you can afford. Here is what that means in practice.
Batch-Level Traceability
Every production run is assigned a batch number tied to raw material certificates and in-process QC records. Certificates of Analysis are issued as standard — no surcharge, no chasing.
Custom Formulation Service
Standard grades cover most applications. When your film specification, base resin, or end-use standard sits outside those parameters, the application lab reformulates specifically for your process — typically within two to three weeks.
Factory-Direct Pricing Structure
No intermediary margin is built into the price you receive. Volume commitments unlock tiered pricing that distributor channels cannot match. Spot quantities and trial orders are also welcomed without penalty.
Responsive Technical Support
Questions about dosage optimization, let-down ratio adjustments, or dispersion troubleshooting reach the production team directly. Response time is measured in hours, not weeks.
Consistent On-Time Delivery
Standard production runs ship within 7–15 working days. Forecasting support is available for customers with quarterly purchase programs who need guaranteed slot allocation during peak seasons.
Broad Portfolio — One Supplier
From shopping bag film to automotive interior parts to food-contact certified grades, E-LUCK covers the full application spectrum. Consolidating masterbatch procurement to a single factory simplifies logistics, documentation, and quality alignment.
Frequently Asked Questions
What Buyers Ask Most
Can E30 be used with recycled (rPE or rLDPE) base resins?+
Yes. Because E30 itself uses a recycled PE carrier, it is well-matched to rPE, rLDPE, and rLLDPE base resins. The similar melt-flow characteristics reduce the risk of incomplete dispersion that can occur when combining very different carrier and base-resin viscosities. We recommend running a dispersion test at 2% let-down first, since recycled-content resins can vary in MFI between lots.
Is pre-drying required before processing?+
No pre-drying is required under normal storage conditions (dry warehouse, sealed bags). Moisture content is maintained at less than 0.50% at the time of dispatch. If bags have been opened and stored in a humid environment, a brief drying cycle at 70–80 °C for 2 hours is recommended as a precaution to prevent steam-induced surging in the extruder.
What is the minimum order quantity for a trial shipment?+
Trial orders are available in quantities as low as 500 kg. For customers evaluating E30 against an existing specification, we can provide a sample pack (typically 5–25 kg) to allow lab and line trials before committing to a full order. Contact the sales team with your application details and we will advise the most appropriate trial quantity.
Can the carbon black concentration or filler level be adjusted?+
Yes. E30 is the standard formulation, but the E-LUCK application lab can reformulate for customers who need a different carbon black loading (for example, 40% for a carrier-efficient specification) or a modified filler ratio to hit a specific density or stiffness target. Custom grades typically require a minimum order of 2 MT per run and a 2–3 week development period.
Does E30 carry any environmental or safety certifications?+
E30 is produced within E-LUCK's ISO-certified quality management framework. Safety Data Sheets (SDS) and material declarations are available for all grades. If your application or market requires a specific certification (e.g., REACH compliance documentation, RoHS declaration, or recycled-content certificates for eco-label programs), please request this at the time of inquiry so the appropriate documentation can be prepared.
How does ash content below 32% affect finished film properties?+
Ash content is a proxy for the total inorganic mineral load (primarily from CaCO₃ filler) in the masterbatch. Higher ash levels increase stiffness and can reduce elongation at break in thin blown films. By capping ash at 32%, E30 maintains a balance that allows the filler to contribute cost reduction without significantly impairing the tear or puncture resistance needed for bin liners and shopping bags in typical gauge ranges (15–50 μm).
