View Technical SpecsUnderstanding the shift from monolayer blown film to 3-layer, 5-layer, and 7-layer co-extrusion technology in flexible packaging and industrial applications.
The global flexible packaging market has undergone a fundamental transformation. Modern film extrusion converters are systematically abandoning mono-layer structures in favor of multi-layer co-extrusion systems (ABA, ABC, ABCDE, and ABCDEFG). This technological transition is driven by the imperative need to down-gauge film thickness while enhancing tensile strength, dart impact resistance, puncture resistance, and oxygen/moisture barrier properties.
However, multi-layer co-extrusion introduces complex polymer melt rheology challenges. Each individual film layer (ranging from thin 2-micron skin layers to core structural layers) demands exact Melt Flow Index (MFI) matching, zero thermal degradation at high shear rates, and absolute pigment dispersion down to the sub-micron scale.
How Changzhou Jiazhou Plastic Products solves complex melt flow mismatches, pigment agglomeration, and die build-up in high-speed extrusion lines.
In multi-layer co-extrusion, pigment aggregates greater than 5 microns cause catastrophic stress concentration points, leading to bubble rupture, film pinholes, and reduced tensile strength. Utilizing co-rotating twin-screw extruders with high L/D ratios (44:1 to 48:1) and specialized kneader elements, our PE carrier masterbatches achieve micro-dispersion with particle sizes strictly under 1 micron.
A frequent failure mode in 3-layer ABA co-extrusion is "interfacial wave instability," caused by viscosity mismatches between the masterbatch-loaded core layer and virgin outer skin layers. Jiazhou engineers tailor the Melt Flow Index (ranging from 2.0 to 20 g/10min at 190°C/2.16kg) to seamlessly match the matrix resin (LDPE, LLDPE, HDPE, or metallocene PE), ensuring smooth laminar flow through the spiral die head.

Located in Changzhou, Jiangsu, Changzhou Jiazhou Plastic Products Co., Ltd. leverages China’s elite chemical supply chain clusters to deliver world-class masterbatch at unmatched cost efficiencies.
Spanning 6,000 square meters, our facility houses continuous loss-in-weight gravimetric feeders, twin-screw high-intensity extruders, underwater pelletizing lines, and automated packaging systems. This setup guarantees batch-to-batch consistency for volume orders ranging from 1 ton to 500 tons.
Every single batch undergoes rigorous colorimetric evaluation using Datacolor spectrophotometers under D65, A, and F11 illuminants. We guarantee a tight color tolerance of ΔE < 0.5, ensuring zero color variation across global shipment lots.
Strategically situated in the Yangtze River Delta industrial hub near Shanghai and Ningbo ports, Changzhou Jiazhou maintains strong raw material reserves of organic pigments, rutile TiO2, and prime LLDPE, enabling a standard manufacturing lead time of just 15 days.
Tailor-made additive and color formulations optimized for specific downstream processing methods and demanding end-use environments.
Requires UV stabilizers (HALS), anti-fogging agents, and light-diffusing masterbatches. The outer layer (A) contains long-term UV inhibitors, while the inner layer (C) is loaded with anti-dripping masterbatch to optimize light transmission and crop yield.
Demands high-concentration PE White Masterbatch (up to 70% Rutile TiO2) and PE Black Masterbatch in 3-layer co-extrusion. Provides 100% opacity, extreme tear resistance, and anti-static properties for palletized fertilizer and polymer resin transport.
Integrates PE carrier masterbatches compatible with EVOH and Polyamide (Nylon) tie-layers. Formulated using 100% FDA food-contact compliant organic pigments that exhibit zero color migration during hot-fill or retort processing.
Combines a high-whiteness outer skin layer (for smooth barcode printing) with an ultra-opaque black inner layer (for complete privacy security and tamper resistance).
How Changzhou Jiazhou meets the stringent technical specifications and regulatory audits required by multinational enterprise procurement directors.
Every shipment comes with a full Certificate of Analysis (COA) and verified compliance documentation including RoHS 2.0, REACH SVHC, EU No 10/2011, FDA 21 CFR 177.1520, and Halogen-Free testing certificates.
Using sealed vacuum desiccant packaging, Jiazhou masterbatches maintain moisture levels under 500 ppm, preventing bubble formation, optical voids, and die-lip build-up during high-temperature extrusions.
Our lab provides rapid custom color matching against physical target plaques or Pantone/RAL codes within 48 hours, providing 1kg test samples for high-speed blown film trial runs.
Positioning your manufacturing operations for upcoming environmental regulations and circular economy demands.
As global brand owners mandate 30% to 50% PCR content in flexible packaging, masterbatches must compensate for gel defects, phase separation, and yellowing associated with recycled polyolefin streams. Jiazhou's next-generation PE masterbatches incorporate chain extenders, compatibilizers, and secondary antioxidants to stabilize PCR-containing film layers.
In response to global PFAS chemical restrictions, Jiazhou has developed 100% PFAS-free Polymer Processing Aids (PPA). These non-fluorinated additive masterbatches effectively eliminate melt fracture (shark skin), reduce die build-up, and lower extrusion back-pressure without violating EU/US environmental regulations.
With film thicknesses dropping down to 10–12 microns in agricultural and stretch hood applications, conventional masterbatch fillers can cause film tears. Our nano-dispersed masterbatches ensure defect-free film blowing even at extreme blow-up ratios (BUR 3.5:1) and high haul-off speeds (>120 m/min).
Traditional carbon black absorbs Near-Infrared (NIR) light, rendering black plastic unclassifiable in automated recycling sorting facilities. Jiazhou offers specialized NIR-detectable black masterbatches that allow automated optical sorting systems to identify and recycle PE film fractions.
