The global market for solvent-free polyurethane (PU) plastic-plastic composite adhesives is witnessing robust growth, driven by stringent environmental regulations, rising demand for food and pharmaceutical packaging safety, and the industry’s shift toward eco-friendly manufacturing solutions. This 100% solid adhesive variant is rapidly replacing traditional solvent-based alternatives, becoming a cornerstone in flexible packaging and related sectors.
Industry data shows that the Chinese market for solvent-free PU composite adhesives reached 1.43 billion yuan in 2025, with an 8.3% year-on-year growth, and is projected to hit 1.55 billion yuan in 2026. Globally, the market is expected to expand at a CAGR of 7.5% from 2026 to 2033, fueled by EU REACH regulations and China’s environmental policies that restrict VOC emissions.
Unlike solvent-based adhesives, these solvent-free formulations emit no volatile organic compounds (VOCs), ensuring worker safety and environmental compliance while meeting strict food contact standards. They exhibit excellent adhesion on common plastic substrates such as BOPP, PE, PET, and PA, with high bonding strength and resistance to high-temperature retorting (121℃ for 30 minutes).
Key manufacturers, including Wanhua Chemical, Huitian New Materials, and Kangda New Materials, are expanding production capacity and optimizing formulations. Technological breakthroughs in polyol synthesis have lowered costs, accelerating penetration in mid-end markets like daily chemical labels. The adhesives also support high-speed lamination (up to 450m/min), enhancing production efficiency for packaging enterprises.
With the dual drivers of policy support and market demand, solvent-free PU plastic-plastic composite adhesives are poised to dominate the flexible packaging adhesive market. Experts predict broader applications in automotive and electronics sectors, further boosting market growth in the coming years.
