Tests show that the shape and wall thickness of cans matter. Thicker walls make cans stronger. A thin varnish layer inside the can, only 5 micrometers thick, helps the can handle more pressure. The bottom of the can is dome-shaped. This shape helps stop the can from bursting. These facts show why aluminum alloys are good for making soda cans.
Scientists have studied aluminum alloy 3004 and 5182. Alloy 3004 is best for the can body because it is strong and light. Alloy 5182 is used for the lid and tab because it is even stronger. Using two alloys helps each part work its best. But, it can make recycling harder. Scientists are trying to make new alloys. These new alloys could make recycling easier and keep cans strong and light.
Some soda cans are made from steel or tinplate instead of aluminum. Tinplate is steel with a thin layer of tin on it. People have used tinplate for over 100 years in cans. Tinplate keeps drinks fresh and tasty. The tin coating stops the steel from rusting. This is important for keeping soda safe and good to drink. Tinplate cans are often used for special or fancy drinks.
Studies show tinplate is good because it does not rust and keeps drinks fresh. Tinplate lids seal well and help drinks last longer. Tinplate cans are used for foods and drinks that are acidic. The tin coating rusts before the steel does, so it protects the drink. Only a tiny bit of tin gets into the drink, and it is safe. Rules make sure tin levels in drinks are not harmful.
Industry data shows tinplate cans keep soda safe and tasty. The way they make tinplate includes hot-dip and electro-tinning. This gives a good tin coating. Other treatments, like chromate passivation, make the can even more rust-proof. These things make tinplate a good choice for soda cans, especially when taste matters most.
Both aluminum cans and tinplate cans need coatings inside. These coatings protect the drink and the can. Makers use epoxy or polymer linings to make a barrier. This stops the drink from touching the metal. It also stops rust and keeps the taste the same.
Scientists use special tests to check these coatings. Tests show epoxy and polymer linings protect well against rust. Elemental analysis shows these coatings stop aluminum from getting into the drink. Polyolefin dispersion coatings stick better and protect more than old epoxy coatings. These new linings help cans last longer and keep drinks safe.
A new test uses real soda and pressure to see how coatings work over time. Results show laminate polymer coatings last longer than old lacquer coatings. Sugary drinks can even help protect the coating. These facts show that modern coatings are important for keeping cans safe and drinks tasting good.
Note: The materials used in soda cans, like aluminum alloys, tinplate, and special coatings, help make cans strong, light, recyclable, and safe. Each material and coating has a job to do. They protect the drink and keep it tasting good.
Making soda cans starts with raw materials. Aluminum comes from bauxite, which is a reddish rock. Bauxite is found in many places around the world. Workers dig up bauxite and send it to refineries. Refineries turn bauxite into alumina, a white powder. Factories use electricity to change alumina into pure aluminum. This step is needed for every aluminum beverage can. Bauxite is the main source of aluminum. The life of a soda can begins with bauxite.
Manufacturers also use recycled aluminum. In the U.S., most cans have 73% recycled aluminum. This shows how important recycling is for soda cans. The supply chain for soda cans is global. Bauxite ore is shipped to factories. Good supply chain management keeps production fast and smooth.
Aluminum comes from bauxite ore and is the main material for soda cans.
In 2018, the U.S. made about 1.9 million tons of aluminum packaging for soda and beer cans.
The market for beverage cans is growing, and North America makes the most.
Factories turn aluminum into thin sheets. Machines cut and shape these sheets into can bodies. These machines are very fast and make over 300 cans each hour. They are very accurate, with few mistakes. The walls of the cans are thin, less than 0.1 millimeters thick. Even though the walls are thin, the cans are strong. The bottom of the can is dome-shaped. This shape helps the can hold high pressure.
Production lines use different ways to check how well they work:
Throughput counts how many cans are made each hour.
Cycle time checks how long it takes to make one can.
Overall Equipment Effectiveness (OEE) looks at machine speed, downtime, and quality.
Benchmark Metric | Manual Process | Automated Process | Improvement / Benefit |
|---|---|---|---|
Units Produced per Hour | 100 units/hr | 300 units/hr | 200% more cans made |
Material Waste Percentage | 10% | 2% | 8% less waste |
Labor Cost Savings per Hour | N/A | $20 per worker/hr | Big savings on labor |
Downtime Percentage | 5% | 1% | 4% less downtime |
Modern soda can factories use special tools to find slow spots. They watch the process in real time. Workers learn many jobs to keep things running well.
Recycling is very important for soda cans. Recycling aluminum saves over 90% of the energy needed to make new cans. In 2021, the U.S. recycled 633,500 tons of aluminum cans.

The life cycle of soda cans shows how recycling, mining, and making cans all work together to help the planet.
The shape of a beverage can is not random. Designers choose a cylindrical shape because it gives the can strength and helps it hold pressure. Aluminum alloy 3104 works well for this shape because it is strong and easy to form. The cylindrical design spreads out the force from the soda inside, so the can does not break easily. Factories use deep drawing and necking processes to make this shape. These steps help the can stay strong and use less material.
Cylindrical cans resist crushing and dents better than other shapes.
The wall thickness and a thin varnish layer inside the can add extra strength.
The dome-shaped bottom helps the can handle pressure from carbonated drinks.
A beverage can design with a strong structure keeps drinks safe during shipping and storage. The design also makes the can easy to stack and store, which helps with packaging and transportation.
The opening mechanism is a key part of beverage can design. Most cans use a pull-tab or stay-on tab. This design lets people open the can easily without extra tools. The tab is made from a strong aluminum alloy, which helps it bend without breaking. The lid and tab work together to keep the can sealed until someone opens it.
The tab design prevents sharp edges, making it safe to use.
The opening is just the right size for pouring or drinking.
The mechanism is reliable and works every time.
A good beverage can design always considers how people will use the can. The opening mechanism is a small part, but it makes a big difference in the user experience.
Branding plays a huge role in beverage packaging design. Companies use colors, logos, and special graphics to make their cans stand out. A unique beverage can design can help a brand get noticed on crowded store shelves. Research shows that most people choose drinks based on the brand name and logo. Bright colors and bold designs make the can easy to spot.
77% of shoppers pick products by brand name.
A signature color can boost brand recognition by 80%.
85% of buyers say colors help them notice a brand.
Beverage can design is not just about looks. It helps build trust and loyalty. Companies like Coca-Cola spend billions on branding because it works. Good packaging and design can turn a simple can into a symbol people remember.
Soda cans are easy to recycle. Aluminum can recycling is special because the metal can be used again and again. It does not lose its quality. Around the world, about 71% of all aluminum cans get recycled. Almost 98% of these cans become new products that can be recycled again. This high recycling rate means less trash ends up in landfills. Aluminum cans are recycled more than glass or plastic bottles. In the U.S., over 80% of aluminum cans collected for recycling become new cans. This closed-loop system keeps aluminum in use for a long time. Since 1972, people in the U.S. have recycled over 2 trillion aluminum cans. This shows how important recycling is for sustainability. The life of a soda can often starts with bauxite, but recycling keeps the metal in use for many years.
Tip: Aluminum cans are the most valuable recyclable material in home recycling bins. They help both the environment and the economy.
Using recycled aluminum to make soda cans saves a lot of energy. Making new aluminum from bauxite uses about 210 megajoules for each kilogram. Recycled aluminum only needs about 27 megajoules for each kilogram. This means recycling uses just one-eighth of the energy needed to make new cans. The carbon footprint drops from 12 kg CO2 per kilogram for new aluminum to only 2.1 kg CO2 for recycled cans. Cans made from recycled aluminum create much less pollution and waste. Water use and solid waste also go down when factories use recycled aluminum. These savings make aluminum cans a great choice for sustainable materials.
