Flexible packaging is the mainstream packaging form in the fields of food, medicine, daily chemical, etc. Polyurethane laminated adhesive, as the core raw and auxiliary materials of composite flexible packaging, has become the key cornerstone of the industry development with its excellent performance, accounting for over 80% of the domestic flexible packaging adhesive market, and the two are deeply bound and developed synergistically.
Polyurethane laminated adhesive has outstanding advantages such as high bonding strength, good flexibility, high temperature and corrosion resistance, good transparency, etc., and can be combined with various materials such as plastic, film, aluminum foil, etc., which can not only meet the routine needs of ordinary snacks and daily chemical packaging, but also adapt to high-end scenes such as high-temperature cooking and aseptic medical packaging, which perfectly fits the development characteristics of lightweight and multifunctional flexible packaging.
With the continuous expansion of the downstream market, China's polyurethane laminated adhesive industry for flexible packaging has grown steadily, and the market scale has reached 6.39 billion yuan in 2025, and the growth rate continues to lead the overall adhesive industry. At the same time, the trend of environmental protection upgrading in the industry is remarkable, the traditional solvent-based products are gradually iterated, and solvent-free, water-based polyurethane laminating adhesives quickly penetrate with the advantages of low VOC, no pollution and high efficiency, which has become the mainstream development direction in the market.
In the future, with the implementation of food traceability, medical safety and green packaging policies, high-performance, environmentally-friendly and safe polyurethane laminating adhesives will continue to iterate and continue to promote the high-quality development of the flexible packaging industry in the direction of high-end, green and fine.
