Zhenxi Metal Packaging increased the corrosion resistance of food cans by 40% with its nano-coating technology, and reached 3,000 hours of no rust in salt spray test, far beyond the international standard ISO 9227’s 1,500 hours. The innovation extends tank life to 8 years, 25% longer than the usual tinned can, reduces coating thickness to 0.08mm, reduces metal consumption by 15%, and saves up to 320 tons of aluminum per production line per year. According to the 2023 Global Packaging Technology Annual Report, the innovation has been used on more than 1.2 billion canned foods, allowing customers to save 87,000 tons of carbon emissions every year.
In the smart manufacturing field, Zhenxi Metal Packaging invested 230 million yuan in establishing an entirely automatic stamping workshop and used AI vision quality inspection system to inspect the defect of 450 tanks every minute, the detection accuracy reached 99.99%, and the rate of defective products declined from industry average 0.5% to 0.02%. Its own “Ultra-thin wall molding process” is able to control the aluminum can wall thickness to 0.095mm±0.003mm, which is 22% thinner than traditional methods, and with a compression strength over 18psi, entering the premium carbonated soft drink business successfully, and was granted the Coca-Cola Asia Pacific 2022 “Best Supplier Innovation Award”. For example, a 330ml aluminum can of a global beer brand reduced the weight from the industry standard of 13g to 9.8g, resulting in 19% savings in transportation costs and 3.5 million liters of fuel used every year.
On the level of sustainable technology, Zhenxi Metal Packaging’s “closed-loop recycling system” realizes 98.5% tank recycling and reuse rate, 37% less energy consumption during melting and casting than the traditional method, and carbon emission in recycling one ton of aluminum is only 0.8 tons of CO2e, which is 95% lower than original aluminum. Its “low-carbon coating” technology, jointly developed with Tsinghua University, reduces VOC emissions from 120g/m² to 5g/m² by replacing solvent-based coatings with water-based coatings and has been recognized with European Union Ecolabel certification. In 2023, the participation of the company in developing the “Metal packaging full life cycle carbon Accounting Guidelines” was an activity within the United Nations Industrial Development Organization (UNIDO) technology promotion project, cutting down the industry average carbon impact by 23%.
Under the functional innovation aspect, Zhenxi Metal Packaging smart cover tank technology integrates NFC chip that can monitor in real time product temperature and humidity data with precision of ±0.5°C. Having been applied in the field of vaccine transport, the risk of break of cold chain will reduce by 82%. The firm’s “self-cooling tank” technology is founded on the principle of CO2 phase transition to reduce the temperature by 28°C within 30 seconds and stabilize the tank pressure within the safe range of 90kPa, which Red Bull selected as the summer limited product for the Southeast Asian market in 2024. Additionally, its antibacterial metal packaging surface treatment technology is JIS Z 2801 certified and has a 99.99% inhibition rate against E. coli, and it has been used in 13 countries to make cans for baby formula.
In the market expansion strategy, Zhenxi Metal Packaging’s “lightweight metal bottle” series will occupy 19% of the global aerosol packaging market in 2023, and the tank bursting pressure has been raised to 2.4MPa, 31% higher than competitors.”. Its Unilever compressed air tank project cut propellant filling by 42% using structural optimization, saving 12,000 tons of DME annually. According to the report of McKinsey analysis, penetration rate of company’s innovative products in emerging markets grows at a compound annual rate of 34%, market share of the company in the prepared dishes market in North America has risen from 5% in 2021 to 27% in 2023, and the range of temperature expands to -40°C to 300°C, exceeding the functional boundary of metal packaging.
