What are functional colorants and what functions should they possess?

Summary：It is a masterbatch containing functional additives other than color. The specific function depends entirely on the active ingredients contained.

Recently, the Ministry of Ecology and Environment issued the "Technical Specification for Control of Waste Plastic Pollution" (HJ 364-2022) (hereinafter referred to as the "Specification"). From the date of publication, the "Technical Specification for Pollution Control of Waste Plastic Recycling and Reuse (Trial)" formulated by the former State Environmental Protection Administration in 2007 has been abolished.

Jinlianchuang Plastic Analyst Lu Yanan stated in an interview with China Business News that the implementation of the above-mentioned "Regulations" is based on the 2007 version, which clarifies the methods of plastic waste recycling, specifies control requirements from the source of production, and adds green design to plastic products. The concept of recyclability is integrated into it, including requirements for establishing a recycling ledger. Among them, the concept of preventing "secondary pollution" is emphasized in multiple requirements. For some small workshops, especially those that do not handle environmental pollution properly, they will inevitably be gradually eliminated.
