Plastics; generic identification and marking of plastic products

This technical specification outlines the fundamental principles for marking and identification of plastic products. It establishes a standardized system designed to facilitate the recognition of various polymer materials throughout their lifecycle, from manufacturing to end-of-life processing. The core content details specific symbols and codes used to identify different types of plastics, ensuring consistency across international trade and recycling operations. By implementing these identifiers, manufacturers and recyclers can accurately sort materials, which is essential for effective waste management and resource recovery. The document provides guidance on the placement, legibility, and durability of these marks on diverse plastic items. It serves as a reference for labeling requirements applicable to both finished goods and raw materials. The approach described promotes uniformity in communication regarding material composition, aiding in the reduction of environmental impact through improved sorting efficiency. Adherence to these guidelines supports global efforts in managing plastic waste streams and enhancing the circular economy. This framework remains a foundational element for industry compliance and environmental stewardship in the plastics sector.
