Breaking Through in Food Packaging: Jiangnan University Leads Domestic Innovation in High-Barrier Materials
The first phase of their globally pioneering initiative—centered on natural extract-based high-barrier materials—has completed a year of stable operation, producing cost-effective, oxygen-resistant, and heat-tolerant functional materials poised to reshape the industry.
Revolutionizing China’s Packaging Independence
For decades, China’s food packaging sector has relied heavily on imported high-barrier materials, with over 80% of advanced materials sourced abroad. This dependency stifled innovation and competitiveness. Prof. Wang’s team tackled this challenge by integrating proprietary synthesis technology with natural active material extraction, purification, and modification. Their research revealed the oxygen, moisture, and light-blocking mechanisms of 2D layered materials, overcoming barriers in extreme environments (high temperature, humidity, low pressure) and specific conditions like microwave heating or sterilization.
The results a breakthrough in long-lasting, stable, and high-performance natural barrier materials that have already achieved:
- Aluminum-free packaging: Redefining food packaging with eco-friendly solutions.
- Commercial success: Chlorine-free packaging products generating nearly ¥100 million in annual sales.
- Industry partnerships: Collaborations with global giants like Yinjinda, and Sealed Air China are underway, signaling broad market adoption.
The Visionary Behind the Innovation: Prof. Wang Jun
Awarded the “Outstanding Contribution Award for Modern Packaging Engineering in China” and recognized as a Fujian Minjiang Scholar and Jiangsu Provincial Academic Leader, Prof. Wang is a pivotal figure in packaging science. His roles include:
- Editor-in-Chief of Packaging Technology and Science.
- Global Council Member of the International Association of Packaging Research Institutes (IAPRI).
- Key Contributor to China’s national packaging regulations.
With over ¥50 million in research funding from national key R&D programs, NSFC grants, and industry partnerships, Prof. Wang has published 100+ papers in top-tier journals and holds 5 national patents. His annual “Top 10 Trends in Packaging” reports have guided industry innovation for 11 consecutive years.
Redefining Sustainable Packaging
This innovation not only breaks foreign monopolies but aligns with global sustainability goals. By replacing traditional aluminum and plastic layers with natural extracts, the team addresses environmental concerns while enhancing food safety and shelf life.
Looking Ahead: As Phase 1 transitions to large-scale production, the project sets a new benchmark for China’s packaging autonomy and positions Jiangnan University as a global leader in packaging materials science.
