Plastic pelletizing recycling machine is a device used to convert waste plastic into recycled pellets after processing. These pellets can be used again to manufacture plastic products, thus realizing resource recycling. However, in the market, there is a growing demand for individualization of the color of recycled plastic pellets, so color customization in the production process has become particularly important.

Why customized colors for recycled pellets?

  • Diversified market demand: In the plastic product manufacturing industry, color is one of the most important considerations in product design. Consumers have different color preferences and needs. Therefore, plastic pelletizing machines that produce plastic pellets need to offer diverse color options to meet market demand.
  • Improve the application range of recycled plastic pellets: Plastic pellets of different colors can meet the needs of different fields. For example, the construction field often uses colored pellets in the concrete filling, while household goods may require specific colors of recycled pellets. By customizing colors, plastic pellets produced by waste plastic extrusion machines can be used in a wider range of applications.
  • Increased product value: Custom-colored recycled pellets can add value to plastic products. Colors that meet specific design requirements can enhance a product’s brand image and market recognition.

Methods of customized color for plastic pellets

Sorting treatment

Before the production of recycled pellets in plastic pelletizing machines, sorting treatment can be used. This process involves the use of optical or manual sorting techniques to separate plastics of different colors to obtain a single color of waste plastic to produce recycled pellets of a specific color.

Color additives

The most common method is to add color additives to the plastic pelletizer production process. These additives include pigments, masterbatches, etc., which directly impart the desired color to the pellets. This method is simple and easy to use and allows for quick color customization, but requires precise control of the amount and ratio of additives used to ensure pellet color stability and quality.

Color mixing and blending

A certain degree of color customization can be obtained by mixing different colors or different types of plastic waste and blending the raw materials before processing in the plastic recycling pelletizer machine. This method is more flexible, but it also requires precise control of the raw material ratios as well as the mixing process to ensure that the final recycled pellet meets the customer’s desired color requirements.
