In the global drink market, 63% of packaged drinks are 500ml aluminum cans (Euromonitor International 2023 statistics), and its main advantage is the best cost-effectiveness per unit volume – compared to 330ml cans, 500ml aluminum cans use only 22% more aluminum per can (from 13g to 15.8g). However, the filling increased by 51.5%, reducing the cost of beverage packaging per milliliter by 19% (Ball Corporation production statistics). Coca-Cola’s 2022 annual report shows that its 500ml product range is responsible for 58% of its global canned beverage revenue, with more than 48 billion cans sold per year per pack size. Logistically, from an efficiency perspective, the typical pallet can contain 4,320 500ml aluminum cans (stacked 1.8 meters high), with 23% more liquid than 330ml cans, and reducing carbon emissions through transport by 14% (fedex green logistics model).
Technical conversion on the manufacturing side invokes economies of scale, with high-speed tank filling lines such as the Stolle X1 series operating 500ml cans at maximum speeds of up to 4,000 cans/min, 15% higher than 250ml cans, and 40% lower mold change times (KHS Group equipment parameters). Material science breakthroughs have reduced the thickness of the tank wall from 0.28mm to 0.24mm (Ardagh Group’s 2021 breakthrough), conserving 0.3 cents per can of aluminum without compromising on the compressive strength of ≥90psi (ASTM standard), conserving $600 million in yearly worldwide production of 200 billion cans. Consumer behavior studies have proven that a 500ml size equal to the median adult drinking volume (480±30ml) has a 3-hour cooling capacity at 35 ° C 41% higher than PET bottles (Nestle 2020 Thermodynamic test).
Environmental attributes add to the market appeal, 500ml can aluminum remelting and recycling energy consumption of 8.7MJ/kg, 92% lower than comparable capacity glass bottle (European Aluminum Association life cycle assessment). After AB InBev’s introduction of 500ml cans in Brazil, the recycling levels there increased from 31% to 67% (ESG Report 2022), as the quantity is more compact (up to 1.2kg/m³ density), resulting in the returns of recyclers being higher. Market innovation includes Kirin’s 500ml ultra-slim tank (having a weight of 11.5g, the lightest in the industry), structurally designed to achieve 220N axial load strength (18% higher than ordinary tanks). In spite of stiff competition from 250ml mini cans (12% annual growth), the 500ml size still has a 76% consumer preference (Nielsen 2023 survey) and its 58mm tank mouth diameter is perfectly designed for ergonomic grip (78% palm contact), and is therefore an industrial design example of equilibrium between functionality and advantage.
