Printed cans' Matte and Glossy surface treatment technologies have been used extensively in the marketplace, and a large cost difference, touch and brand positioning difference exist between the two. The matte coating is achieved with a UV curing process (energy consumption of 1200W/m²), a coefficient of friction (COF) of 0.3-0.5, and a scratch resistance strength of 3H pencil hardness. It costs 15%-20% more than the glossy coating. For instance, after the introduction of PepsiCo's 2023 limited edition matte can (Pantone color difference ΔE<1.5), its store appeal increased by 40%, consumer touch tests showed that the liking rate reached 67%, but the cost per can increased by 0.05 US dollars. Conversely, glossy cans for Carlsberg employ high-gloss varnish (with reflectivity of ≥85%), the line speed is up by 12% (to 60,000 cans/h), sales volume has risen 11% by 2022, and marginal profit is up by 8%. Technical specifications have a direct influence on the decision. Matte printed cans' coating thickness is usually 8-12 microns (5-8 microns for glossy) and takes 20% longer time in drying (48 hours), but has 50% greater anti-fingerprint property. The Christmas Glossy can of Coca-Cola (having a local UV region as 30%) increases visual effect via reflective light, reduces shelf stay time per consumer by 1.3 seconds, and improves purchase conversion rate by 19%. The matte black cans of Japanese Kirin Beer (surface roughness of Ra≤0.8μm) raised the repurchase rate from 58% to 73% due to the touch difference. The printing defect rate (e.g., bubbles) is 1.2 percentage points higher compared with glossy cans, and there is an additional cost of quality inspection of 3 US dollars per thousand cans. Printed standard 500ml aluminum cans Consumer behavior data shows that the choice between matte and glossy coatings is highly associated with the category. Nielsen's report in 2023 shows that 72% of premium alcoholic drinks' matte cans (such as Johnnie Walker's Blue Formula whisky cans) have a mean transaction value 22% greater than matte cans, and 86% of matte cans (such as Magic Paw Energy drinks) in the functional beverage category have seen their impulse buying rate increase 31% due to the "vitality" label. Glossier beauty company's matte lip balm packaging (with a touch satisfaction score of 4.7/5) has been posted on social media 5.4 million times, 180% more than that of the glossy one. Environmental protection trends reframe process choices. The EU's 2024 Sustainable Packaging Regulation mandates that VOC emissions of matte coatings must not exceed 50g/m² (initially 120g/m²), which has decreased the price of water-based matte inks by 28% (solid content ≥65%), but raised the energy consumed for drying by 18%. Anheuser-busch InBev's carbon-neutral matte cans (carbon footprint 1.2kg CO₂ per can) offset costs with carbon credits and achieved a 14% sales increase in 2023. On the other hand, the share of glossy cans in fast-moving consumer goods rose from 58% in 2020 to 63% in 2023 using UV-LED curing technology (40% energy saving) (Smithers data). Groundbreaking integration solutions are breaking through limitations. Red Bull brought out "Hybrid Finish" printed cans (local base matte color + high-gloss logo) in 2024. The cost of production added 12%, but the shelf visibility was enhanced by 90%, and the sales in the first month exceeded 230 million US dollars. Chinese supplier Orekin's innovation of the intelligent temperature-variable matte coating (response temperature 10-40℃) enables the tank pattern to change according to the refrigeration condition, increasing the premium capacity of the product by 25% and the production cycle by only 2 days. Interpack predicts the matte/glossy blending process will account for 39% of the market for printed cans in 2025, driving the average profit per can to increase to 18.7%.
