is not high. In 2021, according to the company's aluminum foil output, the top five accounted for about 30.9%, of which GNEE accounted for the highest proportion at 14%, followed by Chang Aluminum Co., Ltd. accounting for 5.5%, although the market share of leading companies accounts for a large part , but there are still a large number of small and medium-sized enterprises active in this market.

Secondly, the brand battle also lies in product innovation. As consumers' demands for product packaging become increasingly diverse, aluminum foil coil companies need to continue to innovate to meet market demand. Some companies have developed new products with independent intellectual property rights through cooperation with scientific research institutions, such as high-barrier aluminum foil, antibacterial aluminum foil, etc. These new products not only improve the protective properties of packaging, but also provide consumers with healthier and environmentally friendly options.
