High-concentration pigment dispersions optimized for high-speed tubular film co-extrusion and injection processes.
Founded in 2010 and strategically located in Changzhou, Jiangsu Province, Changzhou Jiazhou Plastic Products Co., Ltd. has grown over 16 years into an authority in polyolefin masterbatch formulation and extrusion technology. Our facility spans over 6,000 square meters, fully integrated with multi-stage co-rotating twin-screw extrusion lines, high-shear mixing units, and advanced colorimetric quality testing equipment.
As a specialized high-concentration PE masterbatch manufacturer, Jiazhou bridges the gap between raw pigment physics and high-speed film processing. We engineer masterbatch solutions engineered specifically for Linear Low-Density Polyethylene (LLDPE), Low-Density Polyethylene (LDPE), and High-Density Polyethylene (HDPE) film extrusion systems, satisfying complex industrial demands across food packaging, agriculture, construction, and consumer goods.
In modern plastic blown film extrusion, the quality of color masterbatch is paramount to maintaining bubble stability, tensile strength, and optical uniformity. Blown film is an intricate process where molten polymer is extruded vertically through a circular die, expanded by internal air pressure, and cooled by an external air ring. Any micro-agglomeration of pigment or carrier resin mismatch introduces critical structural defects such as pinholes, gel spots, melt fracture (sharkskin), and gauge variation.
A fundamental failure mode in film coloring occurs when carrier resins possess a lower Melt Flow Index (MFI) than the matrix resin, leading to localized shear heating and un-melted masterbatch core regions. Jiazhou utilizes high-MFI (15–30 g/10min at 190°C/2.16kg) virgin LLDPE/LDPE carrier resins with targeted molecular weight distribution (MWD). This guarantees rapid shear-induced melting and perfect molecular entangling within the host polyolefin matrix without reducing the tensile strength or dart impact resistance of the final film.
In pigments such as Rutile Titanium Dioxide ($TiO_2$) or Carbon Black, surface energy dictates agglomeration behavior. Organic pigments used in Jiazhou masterbatches undergo specialized hydrophobic wax coatings and hyper-dispersant surface treatment. This reduces the primary particle agglomeration from tens of microns down to sub-micron scales ($< 0.3 \mu m$), preventing light scattering anomalies and ensuring intense color strength at minimum let-down ratios (LDR of 1% to 3%).

As a global exporter supplying masterbatches across more than 100 countries in Europe, North America, the Middle East, Southeast Asia, and South America, Changzhou Jiazhou maintains compliance protocols tailored to destination country regulations.
The polymer industry is undergoing a transition driven by circular economy imperatives and intelligent manufacturing. Jiazhou's R&D department is focused on three technology vectors:
Traditional carbon black absorbs Near-Infrared (NIR) light, preventing automated optical sorting in recycling plants. Jiazhou's next-gen NIR-black masterbatch allows automated optical sorters to detect host PE resins, enabling black plastic packaging recycling.
Developing color masterbatch systems utilizing bio-polyethylene (Bio-PE), PLA, and PBAT carriers. Designed for 100% biodegradable agricultural films and compostable shopping bags without degrading composting kinetics.
Incorporating nano-silica and nano-zinc oxide into masterbatches to combine anti-blocking, anti-fogging, UV shielding, and antimicrobial capabilities within a single ultra-concentrated masterbatch pellet.
