I. Exhibition Highlights: Focusing on Green Innovation, Together Crafting a New Blueprint for the Industry

From November 3 to 5, 2025, the 2025 (Hangzhou) Paper-Based Materials Exhibition, themed “Green, Innovation, and Integration,” successfully concluded at the Hangzhou International Expo Center. As the annual flagship event in the paper-based materials sector, the exhibition brought together more than 150 leading industry players, spanning an exhibition area of 10,000 square meters and covering the entire value chain—including specialty papers, green packaging, papermaking chemicals, fiber raw materials, and machinery—drawing nearly 10,000 professional visitors for on-site networking and exchanges. Concurrent with the show, a series of high‑level forums were held, such as the “Specialty Paper Industry Development Forum” and the “Forum on the Integrated Development of Green Paper-Based Packaging Materials.” Industry experts and corporate representatives gathered to engage in in-depth discussions on pressing topics like sustainable development, smart manufacturing, and technological innovation, injecting strong momentum into the high‑quality growth of the paper-based materials industry.

As an innovative enterprise deeply rooted in the biotechnology sector, Hunan Sentai Biotechnology Co., Ltd. was invited to participate in this exhibition, joining industry peers at this grand event dedicated to green transformation and technological integration, and comprehensively showcasing the company’s R&D capabilities and industrialization achievements in the field of bio-based materials.

II. Exhibition Highlights: Empowering with Biotechnology to Create Sustainable Solutions

At this year’s exhibition, Hunan Sentai Biotechnology showcased its core philosophy of “Bio‑Intelligent Manufacturing, Green Empowerment.” Its thoughtfully designed booth, with a sleek and sophisticated aesthetic and a striking brand identity, drew the attention of numerous industry leaders, buyers, and media representatives. Focusing on the green transformation needs of the paper‑based materials sector, the company highlighted three major product portfolios and comprehensive solutions, underscoring the transformative power of biotechnology in revitalizing the traditional paper‑based industry.

Bio-based Functional Additives Series Targeting applications such as specialty papers and food‑grade packaging, the series showcases our proprietary bio‑based, fluorine‑free oil‑repellent agents and biodegradable strength enhancers. Notably, the bio‑based, fluorine‑free oil‑repellent is formulated with 100% renewable natural polymers and has passed SGS fluorine‑free testing, achieving an oil‑repellency rating of Kit level 6 or higher. It seamlessly complies with the latest environmental regulations in Europe and North America, offering a compliant, eco‑friendly protective solution for the food‑contact paper packaging industry. During on‑site demonstrations, its outstanding heat‑resistant oil performance and excellent process compatibility won widespread acclaim from numerous buyers.

Bio-based Fiber Materials System: The exhibit showcased bio-based nanocellulose materials used for paper‑based reinforcement and coating modification. These materials combine high strength, biodegradability, and excellent biocompatibility; they weigh only one-fifth as much as steel yet boast more than five times its strength. They are suitable for a wide range of applications, including wet‑end chemicals and coating chemicals, offering the paper industry a lightweight, high‑performance material option to support upgrades. At the event, numerous representatives from paper‑making companies expressed interest in collaborative testing.

Comprehensive Green Packaging Solutions In alignment with the “Green Packaging” exhibition zone, we showcased end-to-end capabilities spanning the entire value chain—from bio-based raw materials to biodegradable paper packaging. Our offerings include eco-friendly sizing agents, bio-based coating materials, and recycling‑enhancing additives, among other complementary products. By providing integrated “raw materials–additives–applications” services, we help downstream companies achieve green transformation across the full lifecycle of their packaging products.

During the exhibition, the company’s technical team engaged in in-depth interactions with attendees, offering tailored solution consultations to address customer needs such as environmental compliance, performance upgrades, and cost optimization. On-site, more than 20 preliminary cooperation agreements were reached, and over 50 pieces of valuable market‑demand information were collected.

III. Takeaways from the Exhibition: Connecting Industry Resources and Gaining Insights into Market Trends

During this trip to Hangzhou, Hunan Sentai Biotechnology not only achieved the dual objectives of brand promotion and market expansion but also gained valuable insights for future growth through industry networking.

Brand influence continues to grow. Through face-to-face interactions with industry leaders and professional buyers, the company’s “Innovator in Bio-based Materials” brand image has been further strengthened. Many attendees expressed recognition of Hunan Sentai’s deep expertise in the biotechnology sector, laying a solid foundation for future market expansion.

The industrial cooperation network continues to expand. During the exhibition, the company reached preliminary strategic cooperation agreements with more than ten upstream and downstream enterprises spanning papermaking, packaging processing, and raw material supply. Meanwhile, it engaged in technical exchanges with experts from research institutions such as Zhejiang Sci-Tech University and the China Pulp & Paper Research Institute, forging new bridges for industry–university–research collaboration.

Accurately grasping industry trends: By participating in concurrent forums and engaging in industry exchanges, we gained an in-depth understanding of the paper‑based materials sector’s development trajectory toward “greenification, functionalization, and intelligentization.” In particular, new environmental regulations in Europe and North America have driven a sharp surge in demand for fluorine‑free materials and biodegradable products, while the application scope of bio‑based materials in the specialty paper segment continues to expand—providing critical insights for the company’s future product R&D and market strategy.

IV. Future Outlook: Leveraging Biotechnology to Drive the Green Transformation of the Industry

The 2025 (Hangzhou) Paper-Based Materials Exhibition has concluded successfully, marking not only a highly productive market‑driven journey but also a new starting point for Hunan Sentai Biotechnology as it deepens its commitment to green biotechnology. Moving forward, the company will seize this exhibition as an opportunity to focus on three key areas and continue to drive progress:

1. Deepen R&D: Increase investment in the development of bio-based materials, with a focus on breakthroughs in high-performance, low-cost bio-based additives and fiber technologies, thereby refining our product portfolio to meet the paper‑based materials industry’s growing demand for diversification and premium‑grade solutions. 2. Expand Market Presence: Leveraging the collaborative relationships established at this exhibition, we will prioritize expanding into the East China market while extending our reach to key paper‑based industrial hubs such as the Yangtze River Delta and the Pearl River Delta, thus accelerating the large‑scale adoption of bio‑based products. 3. Build an Ecosystem of Collaboration: Actively engage in deep partnerships with upstream and downstream enterprises and research institutions to co‑create an innovation ecosystem for bio‑based materials, fostering the seamless integration of sustainable practices and smart manufacturing within the paper‑based materials sector, and injecting greater “SenTai strength” into the industry’s green transformation.

Green development begins with technology. Hunan Sentai Biotechnology will remain committed to its original mission of “empowering the green industry through biotechnology,” continuously driving innovation and pursuing meticulous, high‑quality growth. Together with industry partners, we will advance hand in hand and jointly write a new chapter in the high‑quality development of paper‑based materials.
