Processing techniques for PET master batch
PET color masterbatch is commonly used in various polyester processing techniques, delivering excellent dispersion and color stability in the molten state. Below are the most common processing methods for PET masterbatch:
Injection Molding: Primarily used for PET preforms and transparent containers, with typical processing temperatures ranging from 260–300°C. During injection molding, PET colour masterbatch rapidly melts and thoroughly blends with PET resin, ensuring uniform color and high transparency in preforms. This process does not affect PET’s inherent viscosity, maintaining excellent stretchability and mechanical strength during subsequent blow molding.
Extrusion Molding: Widely applied for PET sheets, packaging films, and BOPET films. Color masterbatch must exhibit high temperature resistance and excellent melt dispersion to prevent color streaks, yellowing, or crystallization during high-speed extrusion. High-quality PET master batch enhances film gloss, thickness uniformity, and overall optical performance.
Stretch Blow Molding: PET preforms undergo biaxial stretching and blow molding after heating, producing beverage bottles, mineral water bottles, oil containers, and similar products. During stretching, the bottle walls achieve uniform thickness and stable color without decomposition or migration. The finished products feature refined appearance and minimal color variation, meeting stringent aesthetic requirements in the packaging industry.
Co-extrusion: Suitable for producing multi-layer PET structural materials like high-barrier films, protective films, and functional packaging sheets. Masterbatch for PET must exhibit excellent interlayer compatibility within multi-layer structures, ensuring color is uniformly distributed within the target layer without migrating to other structural layers.

Advantages
- High Transparency: PET color master batch maintains brightness and clarity during high-temperature processing, reducing color spots and haze while enhancing overall visual appeal. Ideal for transparent or translucent products.
- Excellent Dispersibility: Pigments disperse uniformly within the PET matrix, improving coloration efficiency and reducing required dosage. Typically achieves desired hues with minimal addition, without compromising bottle strength or transparency.
- Superior Thermal Stability: Exhibits outstanding heat resistance and degradation resistance, accommodating high processing temperatures (250–300°C). Prevents yellowing or color drift during processing, enhancing product quality.
- No Impact on Mechanical Properties: Does not alter PET’s inherent viscosity (IV value) nor affect product compressive strength, bottle rigidity, or impact resistance.
- Environmentally Safe: Meets international food-grade standards including FDA, EU, and RoHS requirements, ensuring safety and reliability for applications such as mineral water bottles, edible oil containers, and cosmetic packaging.
- Highly Customized: Offers color customization based on Pantone, RAL, or physical samples, providing opaque, transparent, pearlescent, fluorescent, and other effects to rapidly match brand visual requirements.
