What are the main components of blown film color masterbatch?

In the production process of plastic film, blown film color masterbatch plays an indispensable role as a key coloring material. It not only endows the film with rich and colorful colors, but also affects the performance, stability, and service life of the film. So, what are the main components of blown film color masterbatch?

Carrier resin

The carrier resin is the basis of blown film color masterbatch, which determines the compatibility and processing performance of color masterbatch with plastic substrate. Common carrier resins include polyethylene (PE), polypropylene (PP)

Ethylene vinyl acetate copolymer (EVA) and other resins have good compatibility with the plastic substrate used in the blown film process, ensuring that the color masterbatch is evenly dispersed during processing, avoiding agglomeration and clumping.

Pigments or dyes

Pigments or dyes are the core coloring components in blown film color masterbatch, which determine the final color of the film. Pigments are usually tiny particles that are insoluble in plastic substrates and are separated by physical means

Distributed evenly in the carrier resin in a dispersed manner. And dyes can dissolve in plastic substrates, forming a uniform coloring layer. According to different application requirements and aesthetic standards, different types of pigments or dyes can be selected to mix the desired color.

dispersant

Dispersants play a crucial role in blown film color masterbatch. Due to the large specific surface area and high surface energy of pigment particles, they are prone to agglomeration during processing

Aggregation affects the coloring effect and transparency of the film. Dispersants can adsorb onto the surface of pigment particles, reducing their surface energy and promoting uniform dispersion of pigment particles in the carrier resin. Meanwhile, dispersants can also improve the processing stability of color masterbatch, reduce energy consumption and wear during the processing.

additive

In addition to the main components mentioned above, blown film color masterbatch may also contain a series of additives to improve its performance or meet specific application requirements. For example, antioxidants can slow down

The oxidation degradation of color masterbatch and film improves the service life of the product; Light stabilizers can absorb or reflect ultraviolet radiation, protecting the film from photoaging; Antistatic agents can reduce thinness

The surface resistance of the membrane reduces the accumulation of static electricity and the adsorption of dust. The types and amounts of these additives will be adjusted according to specific application scenarios and customer needs.
