The full name of color masterbatch is called color masterbatch. It is a new type of special colorant for polymer materials. It is composed of three basic elements: pigments or dyes, carriers and additives. The resultant aggregates contained in the resin can be regarded as pigment concentrates, so its tinting power is higher than the pigment itself. Color masterbatches are mainly used in plastics to achieve the desired color effect in plastic or rubber products. Masterbatch can be divided into different grades:

1. Injection color masterbatch: used in cosmetic packaging boxes, toys, electrical appliances and other products.

2. Ordinary injection color masterbatch: used for general daily plastic products, industrial containers, etc.

3. Blown film masterbatch: used for blow molding coloring of ultra-thin products.

4. Ordinary blown film masterbatch: used for blow molding and coloring of general packaging bags and woven bags.

5. Spinning masterbatch: used for spinning and coloring of textile fibers. The masterbatch has fine pigment particles, high concentration, strong coloring power, good heat resistance and light resistance.
