While the 500ml size is the industry standard in the drinks industry, there is significant variation in the size of 500ml cans. According to Beverage Can Makers Europe statistics in Europe in 2023, the tank widths of mainstream companies are ranged in 66.0±1.5mm, with their heights varying from 168 to 178mm. For instance, Red Bull’s energy drink can of 500ml has a unique 66.3mm diameter and 172mm height, 4mm taller than the standard Coca-Cola can (66.0mm×168mm). This reduces the shelf space occupation rate by 7% and enhances the refrigeration efficiency by 12% (calculated by DHL Cold Chain Logistics).
Brand differentiation strategies drive size innovation. The 500ml slim can (diameter 64.8mm, height 176mm) launched by Tsingtao Beer in 2024, by reducing the can diameter to accommodate the honeycomb channels of vending machines, increased the distribution rate by 19%, while the can wall thickness was decreased from 0.28mm to 0.24mm without compromising the compressive strength of 45psi (ASTM D4169 standard). The material cost was saved by 9%. The 500ml can of Heineken’s European version stands 180mm tall, with 3% more nitrogen in the regular can to provide the foam with more density. Consumers’ blind taste appreciation has improved by 21% (Nielsen Sensory Research figures).
The filling line compatibility determines the parameter design. AB InBev’s 500ml can bottom concave depth has been increased from 4.8mm to 5.2mm, and the capping machine pressure parameter on the production line has been increased from 38kN to 41kN. Although this has caused a 15% increase in equipment renovation investment, the qualified rate of can cap sealing has increased from 99.2% to 99.7% (KHS Filling Equipment Technical White Paper). Suntory Japan’s 500ml can mouth diameter is enlarged from 53mm to 55mm, with an 18% increase in drinking flow rate and conformity to vending machines’ delivery speed, leading to a 23% increase in a single machine’s daily sales.
Regulatory requirements result in regional variations in size. China’s “Standard for Metal Packaging in Contact with Food” GB 4806.9-2023 stipulates that the overlapping rate of the weld seam of the can body should be ≥15%, which has increased the height of the 500ml can of Yanjing Beer from 169mm to 172mm and the pass rate of the weld strength test from 93% to 99.5%. EU EN 1335 standard requires the compressive strength of the tank bottom to be ≥310 pounds, which forces some brands to increase tank bottom reinforcing ribs from 6 to 8, increase the material consumption by 2.7%, but reduce the transportation damage rate from 0.8% to 0.3%.
The optimization of consumer experience results in non-standard designs. The waistline shrinkage rate of the 500ml can of Kirin Beer is increased by 3% to 5%, the grip friction is increased by 27%, and the slipping possibility in a humid environment test is reduced by 33%. The packaging of Yanki Forest sparkling water employs a narrow diameter 63.5mm design suitable for the average width of a woman’s palm (72±5mm). Blind test comfort score is 19% higher, and the female consumer purchase rate in convenience stores is 14% higher (Kantar 2024 Consumer Behavior Report).
Logistics efficiency enables size innovation. Carlsberg’s 500ml cans have increased the standard pallet loading capacity from 864 cans to 912 cans through reducing the height from 170mm to 167mm, with the unit transportation cost saved by 6%. Coca-Cola’s 500ml conical can shape for the African market (top diameter 62mm, bottom 66mm) has increased the stack stability test tilt Angle tolerance from 15° to 22° and increased the rate of warehouse space usage by 18% (DHL supply chain optimization case).
Precision manufacturing technology breaks through conventional limitations. Ball Corporation’s 500ml light tank has enhanced the shoulder transition Angle from 70° to 65°, increased axial bearing strength from 330 pounds, reduced the tank weight from 23 grams to 20 grams, increased the production line speed from 2000 cans per minute to 2200 cans, and reduced energy consumption by 12% (Sustainability Report 2024). Laser welding technology introduced by Orekin maintains the overlap error of the tank seams within ±0.05mm, improving the air tightness by 0.3 atmospheres compared to the traditional fusion welding process and extending the shelf life to 18 months.
Market data prove the trend of discretization. Euromonitor International statistics show that the standard deviation of the 500ml can dimensions of worldwide 500ml tank sizes in 2024 is 43% higher than in 2015. Including, the standard deviation of diameter from 0.38mm to 0.54mm and that of height from 2.1mm to 3.7mm. This discretization not only originates from the diversity of brand strategies, but also reveals the precise fitting of package technology into consumption scenarios – within the 500ml format of fixed capacity, 500ml can size is becoming a three-dimensional canvas for beverage brands for product differentiation.
