四方合作，PHA水性阻隔涂料完成工业级放大生产

Core Viewpoint - The successful industrial-scale production of PHA water-based barrier coatings at the APP (China) Ningbo base of the Lee & Man Paper Manufacturing Limited marks the first global validation of this technology, paving the way for large-scale commercialization of eco-friendly packaging solutions [2]. Group 1: Industrial Collaboration - The collaboration involved four key players: Micro Factory (PHA raw material supplier), Dubai City (water-based barrier coating technology provider), Lee & Man Paper (leading paper manufacturer), and Hengxin Life (paper cup manufacturer), showcasing a cross-industry innovation model [2][6]. - The entire process from PHA raw materials to water-based barrier coatings, then to PHA food-grade paper, and finally to molded paper cups was completed in just 100 days, demonstrating remarkable efficiency and "Chinese speed" in the supply chain [5]. Group 2: Technical Achievements - Micro Factory provided high-purity and stable PHA raw materials, serving as the source for the synthetic biological manufacturing [6]. - Dubai City successfully developed a stable water-based barrier coating from PHA, addressing key technical challenges such as film formation and heat sealing strength in industrial production [6]. - Lee & Man Paper utilized its advanced industrial production capabilities to conduct industrial-scale testing, effectively integrating PHA water-based coatings with food-grade paper to produce high-quality and efficient PHA water-based barrier food-grade paper [6]. Group 3: Environmental Impact - The successful validation of PHA technology represents a significant step towards addressing the global issue of "white pollution," providing a strong "Chinese solution" for sustainable packaging [2].
