China has introduced new national standards aimed at improving the recyclability of plastic packaging, marking a significant step in aligning the country’s packaging system with circular economy principles. The standards, published by the State Administration for Market Regulation and the Standardization Administration of China, focus on design for recycling (DfR) for two of the most widely used packaging materials: polyethylene terephthalate (PET) and high-density polyethylene (PE-HD).

The standards – Plastics – Guide of Design for Recycling – Part 1: Poly (ethylene terephthalate) (PET) Materials (GB/T 46020.1-2025) and Part 2: High-Density Polyethylene (PE-HD) Materials (GB/T 46020.2-2025) – were officially released on 1 August 2025 and came into force on 1 February 2026. Both are classified as GB/T recommended standards, meaning they provide technical guidance rather than legally binding requirements, although they can become mandatory when referenced in regulations or adopted by companies.

The development of these standards reflects growing global momentum around designing packaging to be recyclable from the outset. During the drafting process, technical concepts from the Golden Design Rules (GDR) developed by The Consumer Goods Forum (CGF) were referenced as part of the research and benchmarking work. These internationally recognised principles aim to guide companies in designing plastic packaging that can be effectively sorted and recycled within existing waste management systems.

According to the drafting notes, the relationship between the Golden Design Rules and the Chinese standards can be seen in both conceptual alignment and specific technical guidance. For example, one of the GDR recommendations encourages the use of transparent and uncoloured PET bottles, or light blue and light green variants, to support efficient recycling. The Chinese standard includes similar guidance, noting that colourless or lightly coloured transparent PET is preferable while opaque or dark materials should be avoided because they limit downstream recycling opportunities.

The standards also demonstrate how international design principles can be adapted to local industrial conditions. China’s packaging waste management system, sorting infrastructure and recycling technologies were taken into account when translating global design guidelines into national technical specifications. This approach allows global frameworks to be applied in ways that reflect the realities of domestic recycling capabilities.

The process involved cooperation between several industry organisations. The China Plastics Reuse and Recycling Association (CPRRA) supported the development of the standards by coordinating technical input and organising the drafting process. Since 2022, the association has also maintained dialogue with the CGF Plastic Waste Coalition to exchange knowledge and benchmark international approaches to circular plastic packaging.

For the packaging industry, the introduction of these standards signals increasing attention to front-end packaging design as a key factor in recyclability. Design choices such as material selection, colour, transparency and compatibility with sorting systems can significantly influence whether plastic packaging is successfully recovered and recycled at scale.

The initiative also highlights broader global efforts to harmonise packaging design principles across markets. As companies operate across multiple regulatory environments, greater convergence in recycling guidelines can help reduce packaging complexity and support more efficient compliance strategies. Industry groups have suggested that similar frameworks may serve as references for emerging packaging regulations in regions such as Latin America, Africa and Southeast Asia.

Looking ahead, further work on recyclable design standards is expected. The CPRRA is currently conducting research related to potential additional GB/T standards covering materials such as polypropylene (PP) and polyethylene (PE) film packaging. Continued technical exchanges with international organisations are also anticipated as part of ongoing efforts to strengthen circular packaging systems.

As global attention on plastic waste intensifies, initiatives like China’s design-for-recycling standards illustrate how collaboration between regulators, industry associations and international platforms can help accelerate the transition towards more circular packaging solutions.
