China’s dual carbon goals of carbon peaking and carbon neutrality have become a powerful driving force for industrial upgrading across sectors. The packaging industry, a vital part of the manufacturing chain, is undergoing an unprecedented green revolution, where solvent-free polyurethane (PU) laminating adhesives stand out as a core material, effectively accelerating the low-carbon transition of the whole industry.
Traditional solvent-based adhesives have long been widely applied in flexible packaging lamination. However, their production and usage generate massive volatile organic compounds (VOCs), require high energy consumption for drying procedures, and produce considerable carbon emissions throughout the lifecycle. Such drawbacks run counter to the national dual carbon roadmap and increasingly strict environmental rules. To cut carbon footprint and control pollution, authorities have rolled out targeted policies to push high-carbon, high-pollution materials out of the market, creating broad room for eco-friendly alternatives.
Benefiting from policy support, solvent-free PU laminating adhesives have gained rapid popularity. Different from conventional products, this type of adhesive features nearly zero VOC emissions and eliminates the need for heating and drying during application. Statistics show that compared with solvent-based adhesives, it can slash overall carbon emissions by over 84% and reduce production energy consumption by roughly 30%. In addition, it leaves no harmful solvent residues, fully meeting safety standards for food, pharmaceutical and daily commodity packaging, which further boosts its market acceptance.
Driven by dual carbon strategies, market demand has maintained strong growth momentum. In recent years, the market penetration rate of solvent-free laminating adhesives in China’s flexible packaging sector has climbed steadily. More packaging enterprises are phasing out old production lines and upgrading to solvent-free lamination technology. Meanwhile, leading adhesive manufacturers keep investing in research and development to optimize product performance, enhancing bonding strength, heat resistance and adaptability to high-speed production equipment. The improved products have also won recognition from overseas buyers, expanding export volume year by year.
The industrial ecosystem is also evolving along with this trend. Upstream raw material suppliers, midstream adhesive producers and downstream packaging manufacturers are working together to build a complete low-carbon supply chain. Many well-known consumer brands have added carbon footprint assessment to their supplier evaluation criteria, prioritizing partners who adopt solvent-free adhesive solutions. This market guidance further consolidates the dominant position of green adhesives.
Industry analysts point out that the dual carbon campaign will continue to deepen in the long run. As low-carbon development becomes an irreversible trend, solvent-free laminating adhesives will see even greater market potential. They will not only serve as a key tool for the packaging industry to achieve emission reduction targets, but also lead the sector to move toward higher efficiency, safety and sustainability.
Looking ahead, technological innovation and policy guidance will jointly push the industry forward. Solvent-free PU adhesives will keep empowering the green upgrade of packaging manufacturing, helping the whole industry stride steadily toward the dual carbon vision.
