The composite film industry is currently undergoing a wave of technological upgrades, with solvent-free lamination technology gradually replacing traditional solvent-based lamination technology and becoming the mainstream trend in industry development. Compared to conventional technologies, solvent-free lamination does not require the use of organic solvents, thereby reducing VOC emissions at the source and aligning with green and environmentally friendly policy requirements. Additionally, this technology boasts advantages such as high production efficiency and stable product peel strength, earning widespread recognition within the industry.

Data shows that in 2022, China's consumption of solvent-free composite materials reached approximately 500,000 tons, with a market size of roughly 12 billion yuan. Compared to 2018, the average annual compound growth rate exceeded 30%, and consumption is expected to surpass 1 million tons by 2025. In terms of technological optimization, solvent-free composite technology has further enhanced product performance—such as temperature resistance and corrosion resistance—by refining adhesive formulations and improving coating processes, thereby meeting the requirements of various application scenarios.

In terms of application areas, solvent-free composite films are widely used in industries such as food, pharmaceuticals, and daily chemicals. Among these, the food packaging sector accounts for over 45%, while the pharmaceutical packaging sector accounts for approximately 30%. In high-end food packaging, solvent-free composite films can effectively enhance the barrier properties of packaging, thereby extending product shelf life. In the pharmaceutical packaging sector, their hygienic safety meets the requirements of GMP regulations. As environmental protection regulations become increasingly stringent, the scope of application for solvent-free composite technology will continue to expand.
