Key Features

 

The color formula can be matched to customer samples, color codes, or standard color plates, with the carrier or dispersion system adjusted for PP, PE, PET, ABS, PS, and other resins. It is used for packaging parts and plastic products where batch color consistency matters. Pearlescent, fluorescent, brightening, UV-resistant, and other functional effects can also be developed when needed. After the approved sample is confirmed, batch production and color management can be arranged for mass production.

Applications

 

  • Injection molding part coloring
  • Blow molded bottle and plastic container coloring
  • Plastic packaging cap and housing coloring
  • Daily-use product, toy, and household plastic part coloring
  • Extrusion sheet, pipe, or profile coloring
  • Colored plastic product projects

Quality Control
 

Plastic 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, color code, resin type, processing method, product thickness, and application environment.

2. How should the dosing ratio be selected?

 

-

The typical dosing ratio is 1%-5%. Transparent, dark-color, or high-hiding products should be confirmed through sample testing.

3. Can the carrier resin be matched to the customer resin?

 

-

Yes. The carrier can be selected and the formula adjusted for PP, PE, PET, ABS, PS, and other resins.

4. How is batch-to-batch color difference controlled?

 

-

Colors are checked against the approved sample and standard color plate. Color, pellet appearance, and batch labels are inspected before shipment.

5. Can the packaging be customized?

 

-

Yes. The standard package is 25 kg/bag. Cartons, pallets, 500 kg bulk packing, or jumbo bags can be selected by order.
