In recent years, vacuum aluminum plating technology has continued to iterate and upgrade, promoting a significant improvement in the performance of aluminum-plated coil products and the continuous expansion of application scenarios. The new vacuum aluminum plating equipment adopts high-precision temperature control and uniform coating technology, which controls the thickness tolerance of the aluminum layer within ±0.01μm, improves the adhesion firmness of the aluminum layer by 30%, and significantly enhances the wear resistance and corrosion resistance of the aluminum-plated coil.
Technological upgrading has driven the development of aluminum-plated coil products towards multi-functionality. In addition to the traditional barrier and fresh-keeping functions, special aluminum-plated coils with antistatic, antibacterial, anti-counterfeiting and other functions have continuously emerged, widely used in high-end food packaging, pharmaceutical packaging and electronic component packaging and other fields. An antibacterial aluminum-plated coil developed by a packaging material enterprise can effectively inhibit the growth of Escherichia coli, Staphylococcus aureus and other bacteria, and has been successfully applied to infant food packaging, with a good market response.

Environmental protection upgrading has become an important direction of technological development. Enterprises reduce material consumption by optimizing the aluminum plating process and reducing the thickness of the aluminum layer, and at the same time select low-volatile organic compound (VOC) materials to promote the green transformation of aluminum-plated coil products. Data shows that in 2025, the sales volume of green and environmentally friendly aluminum-plated coils increased by 38% year-on-year, accounting for 32% of the total sales volume. The industry expects that in the next three years, with the continuous maturity of technology, the market share of environmentally friendly aluminum-plated coils will exceed 50%, promoting the high-quality development of the industry.
