Can vs. Tin — What's the Difference?
By Fiza Rafique & Urooj Arif — Updated on March 1, 2024
A can is a container typically made from metal used for storing and preserving food, beverages, or other products, while a tin is specifically made from tinplate and historically used for similar purposes but can also refer to the material itself.

Key Differences
Cans are cylindrical containers used for the distribution and storage of goods, commonly found in food and beverage packaging. They are made from various metals, including aluminum and steel, and are designed to be airtight to preserve the contents and prevent contamination. The use of cans dates back to the 19th century, with their development significantly impacting food preservation and safety. Cans are recyclable and valued for their durability and longevity, making them a sustainable packaging option.
The term "tin" can refer to both the container made from tinplate and the material itself. Tinplate is steel coated with a thin layer of tin to prevent rusting, combining the strength of steel with the corrosion resistance of tin. Historically, tin was widely used for cans and other containers before the advent of aluminum and other materials. Today, the term "tin can" is often used interchangeably with "can," although pure tin containers are less common. Tin is also valued in various industrial applications for its resistance to corrosion and low toxicity.
Both cans and tins serve the purpose of storing and preserving contents, but the materials and manufacturing processes may differ, reflecting advancements in technology and materials science. Cans made from aluminum or uncoated steel are lightweight and resistant to corrosion, making them suitable for carbonated beverages. On the other hand, tinplate cans are preferred for their aesthetic appeal and historical significance in packaging.
Can production has evolved to include lightweight, recyclable materials like aluminum, offering a modern solution to packaging needs with an emphasis on sustainability.
Tin usage, while less common in contemporary packaging due to alternatives like aluminum, remains important for specific applications requiring the unique properties of tinplate, such as certain food products and specialty items.

Common Curiosities
Can you recycle tin cans the same way as aluminum cans?
Yes, tin cans (tinplate) are recyclable and can be processed similarly to aluminum cans, often through the same recycling facilities.
What is the environmental impact of using cans versus tins?
Both aluminum and tinplate cans are recyclable and sustainable packaging options. However, recycling aluminum requires less energy compared to tinplate, potentially making aluminum cans a more environmentally friendly option in terms of energy consumption.
Why do some people still use the term "tin can" for aluminum cans?
The term "tin can" has historical roots and has remained in use as a general term for metal cans, even though the actual tin content may be minimal or nonexistent in modern cans.
What are the health implications of using cans vs. tins for food storage?
Both aluminum and tinplate cans are coated on the inside to prevent the metal from leaching into the food. The coatings are tested for safety and compliance with food contact regulations to minimize health risks.
Is there a taste difference between beverages in aluminum cans and tin cans?
The interior of cans is usually coated to prevent the metal from interacting with the beverage, minimizing taste differences. However, some people report a slight taste difference due to the type of coating used, not the metal itself.
Why are aluminum cans more common than tin cans now?
Aluminum cans are lighter, more corrosion-resistant, and cheaper to produce than tin cans, making them more popular in modern packaging.
How do you differentiate between a can and a tin in everyday language?
In everyday language, "can" is commonly used for beverage and food containers, regardless of the material, while "tin" often refers to containers for non-food items or is used historically.
Are there any contents that should only be stored in tin cans?
Certain acidic or alkaline foods may be better suited to tinplate cans for their corrosion resistance, although modern coatings and materials offer similar protections in aluminum cans.
Can aluminum and tinplate cans be used for the same types of products?
Yes, both types of cans can be used for a wide range of products, including food, beverages, and other goods. The choice between aluminum and tinplate often depends on factors like cost, product compatibility, and manufacturer preference.
How has consumer preference influenced the use of cans vs. tins in packaging?
Consumer preference for more sustainable and convenient packaging has led to an increase in the use of aluminum cans, which are lighter and more easily recyclable. However, tinplate cans are still preferred for certain products due to their classic appearance and robustness.
How has the use of tin changed over time?
While the direct use of tin in cans has decreased due to the rise of aluminum and improved steel coatings, tin remains important in alloys and coatings for its corrosion resistance and non-toxic properties.
What is the significance of the tin coating on steel cans?
The tin coating on steel (tinplate) provides additional resistance to rust and corrosion, extending the shelf life of canned goods. Tin is more resistant to corrosion than steel, especially against certain food products.
Are there any innovative uses for recycled cans and tins?
Recycled cans and tins are used in a variety of innovative applications, from creating new packaging materials to being repurposed into household items, art projects, and even construction materials in some cases.
How does the manufacturing process differ between aluminum cans and tinplate cans?
Aluminum cans are typically made from a single piece of aluminum through a process called drawing and ironing, while tinplate cans are made by coating sheets of steel with tin, then cutting, shaping, and welding them into cans.
How do you properly dispose of aluminum and tinplate cans?
Both should be recycled according to local guidelines. Aluminum cans can often be recycled curbside, while tinplate cans may need to be taken to a specific recycling facility. It's important to clean and, if required, separate the materials before recycling.
