1.3 Develop a global plastics protocol to guide the redesign and convergence of materials, products and uses
    Today's plastics economy lacks coordination across the value chain, resulting in a plethora of materials, products, labels, collection schemes, and sorting and post-processing systems, thus hindering the development of an efficient recycling market.
    Although there have been many innovation and improvement efforts, these have so far been too fragmented and uncoordinated to make an impact at scale. The Global Plastics Agreement needs a core set of standards as a foundation for innovation. This agreement can provide guidelines for design, labeling, marking, infrastructure for post-use processing, and secondary markets, allowing for regional variation and innovation to overcome existing fragmentation and fundamentally change the economics and market effectiveness of post-use collection, reprocessing.

       1.3.1 Develop and promote the adoption of global plastic packaging design guidelines
   Design is very important to improve the economic benefits after use, and the design choice directly affects the complexity and economy of the process after use.
    Sorting: Packages composed of different elements, such as labels, LIDS, glue, or layers of different materials, can cause separation difficulties. Certain polymer types may also be difficult to separate, such as PVC in shredded PET or oxygen-degradable materials in non-degradable materials. Certain products are more challenging to handle, such as small-size packaging and diaphragms. Some packaging sorting machines are difficult to identify, such as full-body labelled bottles.
    Cleaning: Cleaning challenges do not only arise from pollution, but may also be related to design choices. Certain types of glue and inks may be difficult or impossible to remove from plastics by conventional cleaning techniques, investment in more sophisticated cleaning techniques may be required, and packaging should also be designed so that there is no or little product residue after use.
    Scale: If there are only a small number of specific products or materials, it may face challenges in recycling economics and may be uneconomical to invest in related sorting and/or reprocessing technologies.
   To be successful, the global guidelines for plastic packaging design must be:
Industry oriented. The development of packaging design guidelines requires industry support and promotion, involving key players throughout the value chain, from design to recycling. This work needs to take into account the key challenges and performance requirements in each step of the industrial chain.
   Global. The flow of plastic packaging materials is global, and design decisions in Europe may affect the form and material composition of packaging items that are processed and ultimately used in the United States. Thus, the development of guidelines needs to be coordinated globally to allow for regional differences.
