Product Overview
Liquid Color Masterbatch is a liquid masterbatch product designed for injection molding, blow molding, extrusion, and plastic packaging coloring. Its liquid dispersion system evenly introduces pigments or functional additives into resin, making it suitable for mass production of transparent, light-color, high-gloss, and colored plastic products.

Key Features
- Low-dosing-ratio coloring: It is suitable for transparent colors, light colors, and thin-wall products that require low-dosage color matching.
- Fast dispersion: The liquid form mixes into molten resin and helps reduce color specks, color streaks, and local color variation.
- Suitable for multiple processing methods: It can be used for injection molding, blow molding, extrusion, calendering, and sheet processing.
- More flexible color switching: It is suitable for multi-color, batch, or frequent color-change plastic product production.
- Formula adjustable by resin: The formula can be adjusted according to resin, product thickness, transparency, hiding power, and weathering requirements.
Applications
- Food packaging bottle cap coloring
- PET / PE / PP packaging container coloring
- Blow molded bottle and packaging coloring
- Transparent and translucent part coloring
- Daily-use product and toy part coloring
- Extrusion sheet, pipe, and profile coloring
OEM / Customization Capabilities
- Color customization: Color matching is supported by Pantone, RAL, color plates, sample parts, or customer color samples.
- Resin matching: The formula can be adjusted for PP, PE, PET, ABS, PS, EVA, PLA, and other resins.
- Dosing ratio adjustment: Masterbatch concentration can be adjusted according to transparency, hiding power, and cost requirements.
- Functional additive compounding: UV resistance, anti-static, brightening, pearlescent, fluorescent, and other effects can be added as required.
- Sample confirmation: Color plates, injection molded samples, or customer-resin test samples can be provided.
- Batch standard retention: Color standards can be retained according to the approved sample to reduce color variation in later batches.
QC Process

Quality Control
Liquid Color Masterbatch is produced and controlled according to the approved color sample, customer resin, and batch formula requirements. Key inspection items include color consistency, dispersion, state stability, impurity control, packaging sealing, and batch labeling. Batch orders can be checked against approved samples, and sample results or production updates can be provided during production.
Frequently Asked Questions
1. What information is needed for color matching?
-
It is recommended to provide the target color sample, Pantone / RAL color code, resin type, processing method, product thickness, and final application.
2. How should the dosing ratio be confirmed?
-
The dosing ratio should be confirmed based on color depth, hiding power, base resin color, product thickness, and production testing.
3. Is it suitable for transparent or translucent products?
-
Yes. The formula can be adjusted for transparent, light-color, and translucent products according to resin transparency and product thickness.
4. Is dosing equipment required?
-
A liquid masterbatch metering pump or controller is recommended to reduce dosing fluctuation and manual weighing errors.
5. How is batch-to-batch color difference controlled?
-
Custom colors are matched against the approved sample, standard color plate, or customer sample. Sample results should be confirmed before batch production.
