Engineered for flawless resin compatibility, low neck-in strain, zero pinhole defects, and extreme temperature tolerance up to 300°C.
Unlocking extreme melt drawability, eliminating edge bead phenomena, and ensuring thermal stability in ultra-high-speed lamination processing.
Extrusion coating requires rapid polymer relaxation under high shear strain. Custom PE masterbatch utilizes narrow molecular weight distribution LDPE/LLDPE carrier matrices, matching base resin MFI values between 12 to 25 g/10min (190°C/2.16kg). This prevents melt resonance, thickness variation, and web instability at line speeds exceeding 300 m/min.
By incorporating surface-treated inorganic micro-additives and strain-hardening polymer architecture, our masterbatch formulations minimize the neck-in defect (width shrinkage of molten polymer curtain) and control edge bead build-up. This significantly optimizes trim waste and reduces overall polymer consumption during paperboard or foil lamination.
Thermal extrusion coating operates at elevated melt temperatures (280°C–320°C). Our masterbatches feature hydrophobic pigment surface modifications with moisture levels strictly below 0.05%. This eliminates micro-cavities, volatile off-gassing, die-lip buildup, and pinhole failures in high-barrier liquid packaging layers.
How Changzhou Jiazhou Plastic Products Co., Ltd. combines chemical integration, scale economics, and rigid QA/QC controls to serve worldwide converting enterprises.
Located in the heart of Changzhou’s industrial plastic manufacturing corridor, Jiazhou Plastic leverages direct, long-term strategic relationships with premier global resin synthesizers (Sinopec, PetroChina, Sabic, ExxonMobil). By securing prime-grade virgin LDPE carriers and high-purity inorganic titanium dioxide (TiO2), carbon black, and organic pigment powders, we guarantee complete freedom from recycled contaminant trace elements. This ensures batch-to-batch chemical purity essential for sensitive food-contact extrusion coatings.
Our 6,000m² manufacturing facility operates multiple automated high-torque co-rotating twin-screw compounding extruders equipped with precision gravimetric feeder systems. Continuous melt filtration networks remove particles down to 15 microns. This state-of-the-art compounding technology achieves optimal shear dispersion without thermal over-shearing, maintaining the integrity of functional heat stabilizers, antioxidants, and optical brighteners.
Quantitative performance comparison demonstrating our superior dispersion, low melt pressure filter values, and extreme thermal resilience.

Mitigating legal, health, and environmental compliance risks for global enterprise buyers across strict international jurisdictions.
For paperboard, aluminum foil, and plastic laminate structures intended for food contact (aseptic milk cartons, quick-frozen food pouches), our custom masterbatches comply strictly with US FDA 21 CFR 175.300 (Resinous and Polymeric Coatings) and European Commission Regulation (EU) No 10/2011. Overall Migration Limits (OML) and Specific Migration Limits (SML) are rigorously tested and verified by independent accredited third-party laboratories (SGS, TUV).
Our pigment formulations are completely free from heavy metals (Lead, Cadmium, Hexavalent Chromium, Mercury), polybrominated biphenyls (PBB), and phthalate plasticizers. Fully certified under EU Directive 2011/65/EU (RoHS 2.0) and chemical safety framework REACH (Substances of Very High Concern - SVHC free), protecting brand owners from regulatory recall liabilities.
High extrusion coating temperatures can trigger thermal degradation products known as Non-Intentionally Added Substances (NIAS). Jiazhou integrates high-molecular-weight hindered amine light stabilizers (HALS) and primary/secondary phenolic antioxidant systems. This arrests thermal oxidation pathways, preventing off-flavor, odor transfer, or chemical migration into packaged liquids.
Custom masterbatch formulations tailored to specific coating lines, substrate structures, and downstream converting environments.
White PE masterbatches with up to 70% high-opacity TiO2 loading engineered for liquid packaging board (Tetra Pak formats, paper cups). Delivers brilliant whiteness, pinhole-free liquid barrier properties, strong seal integrity, and excellent Corona treatment retention for secondary printing inks.
Ultra-thin extrusion coating (8 to 15 microns) onto aluminum foil, PET, or BOPP films. Formulated with high-dispersion pigments that maintain optical opacity and uniform coloration without creating stress concentration points or compromising foil adhesion.
Heavy-duty polypropylene/polyethylene woven sack laminations. Color and filler masterbatches formulated with UV-stabilizer packages (UV-944 / UV-770) providing long-term light fastness (Blue Wool Scale 7-8) for agricultural and industrial construction containment.
Extrusion coated PE films onto kraft release paper for industrial tapes, medical packaging, and adhesive labels. Custom rheology prevents surface pinholes and ensures micro-smooth topography for uniform silicone release oil deposition.
Engineered for multi-manifold co-extrusion dies (ABA / ABC structures). Specific functional color masterbatches positioned exclusively in outer tie/sealant layers, maximizing cost efficiency while delivering superior aesthetic brilliance.
Heat-resistant black and functional masterbatches designed for flame-retardant or conductive PE extrusion coating onto architectural insulation foils, glass fiber scrims, and telecommunication cable jackets.
Aligning masterbatch chemistry with circular economy demands, bio-based polymers, and ultra-high-speed converting equipment.
As global packaging directives enforce mono-material recyclability (PE-only packaging structures), Jiazhou is leading the transition with bio-based polyethylene carrier masterbatches synthesized from renewable sugarcane ethanol. These solutions maintain identical melt flow dynamics and thermal performance as conventional fossil PE while reducing product carbon footprint (PCF) by up to 45%.
Modern extrusion coating lines demand thinner polymer coatings to cut raw material costs. Our masterbatch R&D team has developed hyper-dispersed nanometer-scale pigment formulations that enable continuous extrusion coating down to 6–8 microns without web breaking, edge tearing, or optical streaking.
