High-concentration, non-toxic formulations optimized for extrusion, blown film, and injection molding.
In modern rigid and flexible food packaging supply chains, selecting FDA food-certified Polyethylene (PE) masterbatches is not merely a matter of aesthetic color matching—it is a critical exercise in chemical compliance, toxicological risk management, and polymer rheology optimization. As international regulatory bodies such as the US Food and Drug Administration (FDA) under 21 CFR 177.1520 and the European Commission under EU 10/2011 tighten thresholds for low-molecular-weight penetrants, heavy metal traces, and specific migration limits (SML), procurement directors must look past elementary pigment blending.
Changzhou Jiazhou Plastic Products Co., Ltd., leveraging 16 years of compounding engineering expertise, engineers specialized PE color masterbatches and filler masterbatches that meet non-toxic, non-migratory, and high-dispersion standards required by global FMCG brands, pharmaceutical packaging convertors, and industrial film blowers.
Full compliance with olefinic polymer regulations, ensuring carrier resins (LDPE/LLDPE/HDPE) contain zero unapproved processing aids or hazardous low-molecular fractions.
Strict adherence to EU Directive 94/62/EC and RoHS. Total concentration of Lead, Cadmium, Mercury, and Hexavalent Chromium is strictly capped below 100 ppm aggregate.
Formulated to prevent off-flavor or odor transfer into food substrates (milk, mineral water, oils), maintaining organoleptic integrity throughout product shelf-life.
Achieving uniform color values and structural strength in thin-wall food packaging (such as multi-layer blown films under 15 microns) requires total micro-dispersion of inorganic pigments and organic dyes within the Polyethylene matrix. When masterbatches suffer from pigment agglomeration, blow-hole pinholes, web breaks, and visual streaks occur during extrusion.
The Melt Flow Index (MFI) of the masterbatch carrier resin must be engineered higher than that of the matrix resin (e.g., LLDPE or HDPE film grade). Our formulation architecture utilizes narrow molecular weight distribution (MWD) virgin PE carriers with MFI values adjusted between 10 g/10min to 30 g/10min (190°C/2.16kg). This ensures rapid melting, optimal shear thinning, and complete encapsulation of pigment nanoparticles.
High-concentration pigment loading (up to 70% for Titanium Dioxide White Masterbatches, 40-50% for high-grade Carbon Black and organic colorants) relies on multi-pass continuous twin-screw extrusion equipped with high-shear kneaders. Pigments are reduced down to sub-micron particle sizes (<0.5 µm), maximizing opacity, tinting strength, and light fastness.
| Masterbatch Grade | Carrier Resin | Pigment Loading (%) | Heat Resistance (°C) | Primary Technical Advantage | FDA / Compliance Status |
|---|---|---|---|---|---|
| FDA Food-Grade White | Virgin LLDPE / LDPE | 50% - 70% Rutile TiO₂ | 280°C - 300°C | High Opacity, Non-Yellowing, Blue Tinting | FDA 21 CFR 177.1520, EU 10/2011 |
| High-Tech Black Masterbatch | Virgin PE Matrix | 30% - 50% Carbon Black | 260°C - 280°C | High Jetness, UV Absorption, Anti-Oxidant | RoHS, REACH Compliant |
| Custom Color Masterbatches | HDPE / LLDPE | 20% - 45% Organic/Inorganic | 240°C - 260°C | Delta E < 0.5 Color Match, Non-Migration | FDA Food Contact Safe |
| Nano CaCO₃ Filler Grade | LLDPE Base | 75% - 85% Fine CaCO₃ | 250°C | Tensile Retain, Scrim Reduction, Cost Saving | Non-Toxic, Eco-Friendly |
When global procurement managers evaluate potential masterbatch partners, navigating market choices requires looking beyond surface-level pricing. Differentiating between basic trading intermediaries and true OEM/ODM manufacturing facilities (Factories) directly impacts product quality stability, batch-to-batch color repeatability, and overall Total Cost of Ownership (TCO).
Trading brokers and general supply companies often aggregate inventory from multiple unverified small mills. This supply structure introduces critical technical risks for automated plastic converters:

FDA food compliance under 21 CFR 177.1520 requires verifying both the carrier resin purity and the pigment/additive composition. Tests include Overall Migration Limits (OML) using food simulants (n-hexane, 95% ethanol, water), heavy metal analysis (Lead, Cadmium, Hexavalent Chromium), and confirming that all color additives comply with 21 CFR 178.3297 (Colorants for polymers). Jiazhou provides full compliance declarations per batch.
If the carrier resin has an incompatible melt flow index or resin density compared to your primary matrix resin (e.g., LLDPE/LDPE blend), the masterbatch will not melt uniformly. This leads to gel formation, melt strength loss, surface haze, or bubble instability on blown film lines. We match carrier polymers precisely to your process specs to maintain optimal bubble stability and physical strength.
Due to our high pigment loading concentrations (up to 70% in White and up to 50% in standard colors), typical recommended let-down ratios range from 1% to 4% (1:100 to 1:25) depending on required opacity, wall thickness, and color intensity. This high concentration minimizes total masterbatch usage, lowering your per-unit manufacturing cost.
Yes. Our high-temperature masterbatch formulations utilize specialty inorganic pigments and thermally stable organic colorants capable of enduring thermal exposure up to 260°C to 300°C without thermal discoloration, outgassing, or chemical degradation during prolonged molding cycles.
Custom color matching takes 3 to 5 working days upon receipt of target samples or Pantone codes. Once a formulation is approved, standard production order lead time is 15 business days for full container loads (FCL), supported by rapid shipment setup from Shanghai or Ningbo ports.
Our Calcium Carbonate (CaCO₃) filler masterbatches utilize sub-micron, surface-treated nano-scale calcium carbonate particles coated with coupling agents. When added at 10% to 30% loading into PE film or injection formulations, it reduces raw material costs, speeds up cooling cycles by increasing thermal conductivity, and maintains tensile elongation and drop-impact resistance.
