In terminal retail competition, Streamlined cans (Streamlined aluminum cans) are able to improve shelf visibility by 18%-23% through optimizing shape parameters. Nielsen 2023 market data reveal that compared with traditional cylindrical cans, the elliptical shape of slender cans (long to short axis ratio, 1.32:1) increases display volume per unit shelf space by 14% and the number of products presented in a given row from 15 cans to 17 cans. In Coca-Cola’s Japanese market tests, this design raised consumers’ average visual dwell time from 2.1 seconds to 3.4 seconds and the shelf click-through rate by 27%.
Statistics of consumer behavior show that the grip comfort index (based on the ergonomic pressure distribution model) of smooth cans is 19% higher than that of normal cans. Unilever’s new slim cans tea beverage range in Southeast Asia reduced can diameter from 67mm to 58mm, reduced the requirement for holding power by 22%, and increased the buying intention of female consumers by 34%. Procter & Gamble’s eye-tracking experiments prove that its aerodynamic form with surface curvature radius (R=120mm) can speed up the recognition of product information by 0.8 seconds and elevate the reach rate of key marketing features from 76% to 89%.
The breakthrough in printing technology makes the advantages even greater. slim cans made use of digital UV inkjet technology to achieve 450dpi of pattern detail, 157% higher than standard offset print at 175dpi. Red Bull’s 2022 launched limited-release slim cans reduced color saturation variation of the cans when exposed to shelf lighting (3000-5000lux) by 41% through 3D photovariable ink technology and effectively pushed impulse buying from 12% to 19%. As calculated by the International Packaging Association, these innovations have helped bring an average 23% increase in new product sales in the first week of launch, and shortened the payback period from 9.2 months to 6.8 months.
The cost-benefit analysis shows that the premium differentiated by thin cans can finance process upgrading. Anheuser-busch InBev’s European market price strategy demonstrates that the price of the unit 330ml slim can is 0.15 euros higher than the standard can. However, with the inclusion of 12.7% repurchase rate increase, the net profit per can still rose 8.3%. The Nestle Coffee case also demonstrates that its high-tech cans with gradient metal coating increased the rate of shelf conversion by 31%, and return on advertisement expenditure (ROAS) increased from 2.4 times to 3.1 times.
The technical parameters comparison determines the quintessential competitiveness. Thin can compressive strength (as determined by ISO 2248) is 385N, which is 20% higher than the standard tank of 320N, and retail end stack height can hence be increased from 1.2 meters to 1.5 meters without increasing the risk of box collapse. During the North American channel test, Mars Food used this functionality to increase the end rack display area utilization rate by 18%, and average daily sales volume during promotion went up by 2,300 cans. Besides, its 22° can top inclination design has raised the vending machine’s delivery success rate from 91% to 97%, and the failure rate of can jamming has reduced by 63%.
Market trends verify the design value. GlobalData predicts that the compound annual growth rate of sleek cans in the ready-to-drink beverage field from 2023 to 2028 will reach 11.4%, far exceeding the growth rate of 4.2% for traditional packaging. The 2023 financial report of Yanki Forest shows that after switching to sleek cans, the average monthly sales volume of its single store increased from 4,500 cans to 5,800 cans, and the return rate of shelf space (monthly sales per centimeter of shelf) rose from 38 yuan to 51 yuan. The acoustic characteristics of this packaging form (reducing the noise of empty cans dropping by 5 decibels) further decrease the negative customer experience complaints by 37% in the convenience store scenario, strengthening the brand’s high-end perception.
