Masterbatch & Additive is a solid or liquid additive used to add color to plastic materials during the plastics manufacturing process.

With using additives it is possible to improve the usability of existing products or to create new ones by modifying the properties of the basic raw material or adding a supplementary feature to it.

The most common properties created with additives and masterbatches are modifications of surface properties, such as anti-block, slip and anti-slip, and anti-static features. Product properties are often enhanced with, for example, antioxidant and UV stabilizer. Food packaging can be improved by an anti-fog additive.
