Focusing on the Green Packaging Supply Chain: Jinyinlian Participates in the 4th Civil Aviation Green Development Conference
Release time:2026.06.04

The “Civil Aviation Green Catering Products Industry Chain Innovation Forum” held during the conference, themed “From Cabin to Airport – Jointly Exploring Innovation in the Civil Aviation Green Catering Products Industry Chain”, was addressed by Huang Peng, Deputy Director of the Hainan Provincial Development and Reform Commission, who delivered a speech at the forum. The forum further brought green supply chain topics into specific scenarios such as cabin service, airport commercial operations, in‑flight meal supply, and the post‑use pathways of disposable catering products, making the water‑based coated paper supply chain a key issue for the commercialisation of barrier engineering in paper‑based packaging.
At the forum, Wang Jizhou, Chairman of Jinyinlian, shared a keynote presentation titled “A Safe, Stable, and Efficient PHA Water‑Based Coated Paper Supply Chain Solution”. As one of the coating companies that participated early in the commercial application of BoCarbon PHA bio‑based water‑based barrier coatings, Jinyinlian brought the forum’s discussions on green materials, global regulations, and civil aviation scenarios down to the real issues that matter most to the paper‑based packaging industry: Can a new water‑based barrier system be stably coated? Can it be delivered in bulk? Can it adapt to downstream manufacturing systems for cups, boxes, bags, etc.? Can it pass the acceptance tests and generate repeat orders from food packaging customers? This also means that Jinyinlian is not a bystander to the BoCarbon PHA technology route, but an important participant and delivery node that brings this material system into the commercial supply chain of paper‑based packaging.

The industrial logic of this forum was very clear. Professor Chen Guoqiang, from the School of Life Sciences at Tsinghua University and Director of the Tsinghua Center for Synthetic and Systems Biology, established a material science foundation for paper‑based barrier engineering based on the scientific properties, degradation boundaries, and green packaging applications of PHA as a natural polymer material. Associate Researcher Lu Sha, from the College of Environmental Science and Engineering at Tongji University, proposed that green packaging is moving from “material substitution competition” to “final product evidence competition” based on global regulations such as EUDR, PPWR, SUPD, EPR, PFAS, and FDA/GB. Carsten Höhne, Senior Vice President of Global Resins & Additives Business at BASF, shared synergies in sustainable materials, food contact safety, and circular economy trends from the perspective of a global materials company. Lin Fanqiu, Chairman of DoBauCheng Group, focused on the alignment of the BoCarbon barrier engineering system with global green regulations, proposing that innovation in paper‑based catering products cannot stay at the material label, but must return to real scenarios, final products, and post‑use pathways.
Within this industry chain coordinate system, Jinyinlian’s role appears particularly critical. For paper‑based packaging, whether a new barrier coating system has industrial value cannot be judged only by laboratory indicators or material concepts. It depends on whether it can be stably coated, whether it can enter downstream manufacturing systems for cups, boxes, bags, printing, heat sealing, stacking, transportation, and customer acceptance. The coated paper supply chain is precisely the key intermediate layer connecting the upstream material system and the downstream product processing system.

According to the on‑site presentation by Wang Jizhou, Jinyinlian International Supply Chain Management Co., Ltd. has been established for 28 years. It is a holding company of Global Printing (stock code: 002799), a listed subsidiary of Shaanxi Pharmaceutical Group. It owns five wholly‑owned subsidiaries and provides technical services and one‑stop material supply solutions to more than 1,000 printing and packaging companies in Tianjin, Beijing, Guangzhou, Dongguan, and other locations. These industrial accumulations have made it not only a coating processor but also an important participant in packaging material supply chain services and engineering conversion capabilities.
In terms of production capacity and delivery capability, Jinyinlian’s Tianjin plant currently has three coating machines, with an annual capacity of approximately 20,000 tonnes. Through technological upgrades, this will reach about 40,000 tonnes by 2027. The coating paper range covers 30 g to 400 g. For a market like green catering products, which has significant growth potential, capacity flexibility, stable delivery, and regional responsiveness are themselves important bases for customers to decide whether to adopt a technology route.
Wang Jizhou summarised the PHA water‑based coated paper supply chain as “safe, stable, and efficient”. Safety means compliance in food packaging production, quality testing, and supply assurance. Stability means consistent batch coating, reliable end‑use performance, and continuous delivery. Efficiency means that downstream cup, box, and bag manufacturers can smoothly introduce the material into their existing industrial systems, reducing unnecessary line modifications and trial production costs.
In terms of production and testing systems, Jinyinlian stated that it has a 3,700 m² Class 100,000 clean workshop, and has established relevant certifications, quality control, and testing capabilities around food packaging production requirements. Its presentation also noted that the company has an R&D quality team and laboratory testing capability, and has purchased cup forming machines for multi‑scenario validation and simulated post‑sales testing. This means that Jinyinlian does not simply provide a single coating service, but a systematic supply chain capability covering coating, testing, forming data, and customer trial support.
This has practical significance for the BoCarbon PHA bio‑based water‑based barrier coating system. DoBauCheng is carrying out water‑based barrier engineering applications for paper‑based packaging around BoCarbon PHA. BASF provides a global perspective on materials and food contact safety synergies. Micro Structures provides the industrial foundation for PHA bio‑manufacturing. And Jinyinlian, as one of the early coating companies to participate in the engineering application and commercial conversion of this technology route, plays an important role in converting BoCarbon PHA water‑based barrier coatings into stable coated paper products.
As one of the early coating companies to apply BoCarbon PHA bio‑based water‑based barrier coatings for commercial applications, Jinyinlian provides important industrial support for this technology route to move from material solution to batch coating and market delivery. The industrial value of BoCarbon PHA should not remain only in material characteristics such as “bio‑based”, “water‑based barrier” or “compostability as a fallback under suitable conditions”. Instead, through the coated paper supply chain, water resistance, oil resistance, heat seal compatibility, food contact safety, recyclability/repulpability friendliness, and downstream processing performance must be integrated into a testable, verifiable, and deliverable evidence system.
From a civil aviation perspective, Jinyinlian’s value also lies in connecting “high‑standard application scenarios” with “large‑scale supply from the packaging industry”. The value of the civil aviation scenario is not whether a single airline adopts a certain product, but the fact that airlines such as Air China, China Eastern Airlines, China Southern Airlines, as well as airports and in‑flight meal supply chain entities, represent a real‑world operating system that provides a high‑standard, strongly regulated, organisable, and traceable validation window for green catering products. After aviation paper cups, meal boxes, and food packaging bags enter the cabin and airport, they must simultaneously meet multiple requirements: food contact safety, passenger experience, in‑flight meal distribution, supply assurance, sorted collection, and post‑use pathways.
Therefore, Jinyinlian’s role in this forum is not merely that of a supporting unit or a presenting company. It is a representative node in the commercialisation of barrier engineering for paper‑based packaging. This indicates that the next stage of competition in green packaging is not a competition of single‑point materials, but a competition of supply chain system capability. It is not about who can talk better about green concepts, but about who can organise material performance, coating stability, test data, customer adaptability, and batch delivery into an evidence chain that the industry can recognise.
From a sheet of PHA water‑based coated paper to an aviation paper cup, what is truly validated is whether a green material can enter a mature industrial system and be delivered stably, continuously, and efficiently to downstream customers. The collaboration between Jinyinlian, DoBauCheng, BASF, and Micro Structures around the BoCarbon PHA bio‑based water‑based barrier coating system sends an important signal to the paper‑based packaging industry: when material innovation meets a reliable coating supply chain, green catering products truly have the foundation to move from a technology route to market‑scale implementation.
