Tin Cans
Tin cans are considered to be among the most popular packaging materials in the world. These small tin cans are easy and cheap to produce and can be crafted into any color, shape, and design. Tin cans are containers most commonly used in commercial production, to package or store items like food or other products. ‘Tin cans’, also known as ‘ins’; ‘steel cans’; ‘cans’; and ‘steel packaging’, are made of a metal material that is easy to cut, such as aluminium or tinplate steel
Advantages of Tin Cans
More shelf life
Compared to most of the available options such as aluminum and steel, tin offers more shelf life. That is because the tin material does not react with the food material. For the other material such as steel and aluminum, they can easily corrode depending on the acidity of the food packaged thus destroying it. That is the reason why these containers cannot be used for the storage of soups, drinks or pharmaceuticals. But for the tin cans, they are not corrosive, and that’s why they can store food for long without it going bad.
Light weight, easy to handle
The issue of weight is critical when it comes to packaging and transporting the products over a long distance. For most service providers, they charge transport fee based on the weight of the load to be shipped. So if you’re looking for ways to reduce the cost of production, then cutting on the transport would be a perfect way. Tins cans are lightweight, and thus they will help reduce the cost of production. They are also easy to hand compared to their counterparts due to this feature.
Rigid and strong
Tin cans offer incredible flexibility in packaging due to their rigidity and strength features. These are the kind of cans that can maintain their original shape even subject to a high impact. Therefore, you will not have a problem of deformed cans which significantly reduces losses associated with return stock due to deformities. These features also enable to use various forms of transport with worrying about the state of the cans.
Flexible packaging
Tin cans are extremely flexible when it comes to packaging. Due to the various properties that tin material comes with such as high rigidity and strength, these cans offer high flexibility in packaging. You can arrange these cans the way you see best and can also be transported by any means of transport and still retain their original condition. That is something that may not be seen in other types of cans as they can easily deform or destroy the content inside while in transit.

Tin Cans What Are They Made Of
Traditional Tin-Plated Cans
The only product that is produced purely out of tin is tinfoil. This material is often used for scientific experiences but also for wrapping other objects such as chocolate bars. Because tin can be flattened in an extremely thin sheet, it allows us to create a large amount of “plating” out of only a little bit tin. Besides being used to make tinfoil, this plating also often gets applied to traditional containers. It is estimated that one pound of pure tin can produce up to 130 square feet of tinfoil or plating. Thanks to this, tin has become highly popular for plating purposes and is often applied to pure metal cans.
Besides the fact that tin can be easily flattened, there is another reason why it is used as a plating material. Tin does not interact with oxygen thanks to this, it does not rust or tarnish and is highly resistant to corrosion.
Nowadays, we use most tin in the world for the production of tinplate cans. These empty cans mainly consist out of steel or iron that has been finished off with a tin-plating. Due to this, the entire can only consist out of 1 or 2% tin. This forms a coating over the metal in order to protect it from the elements. Because of its protective features, this plating is used for a vast number of commercial objects such as wrappings like tin cans.
Tin cans mainly serve the purpose of canning foods, holding cosmetics, medicine storage, and for keeping candles in the form of candle tins. Regular metals normally react with the acids that are present in these substances after which they begin to corrode. Once this happens, the cans release molecules that can contaminate the content of your packaging while simultaneously destroying the can itself. This has especially caused problems in the past with wrappings made out of lead. These cans were known to leach dangerous toxins into its content. Tin-plated metal cans, however, are entirely safe for holding food, cosmetics, and medicines for a longer period of time thanks to the fact that it’s resistant to acidic combinations. The only downside about traditional tin-plated cans is the fact that they are significantly heavier than aluminium tins. This makes them less convenient and more expensive to transport.
Modern Tin Cans
Generally speaking, tin-plated cans are considered to be the ‘traditional’ way to produce cans. In today’s world, the vast majority of small tin containers for sale are made out of aluminum or different types of treat metal. Any material is suitable as long as it is easy to shape and is resistant to rust and corrosion. Both the traditional tins and modern versions are great for canning purposes and are furthermore recyclable. Thanks to this, manufacturers can strip away the tinplate layer and re-use the iron or steel for scrap metal.
The word 'Tin Can' in today's world is used to sum up all sorts of small metal tins into one category. Most of these modern tin containers are crafted out of aluminum, however, originally this was not the case. Although it is common for people to refer to tin cans and aluminum cans as the same item, these two types of tins are actually quite different from one another.
Tin cans and aluminum cans are used for the same purpose and you will mostly find them being used in the food and cosmetic industries. The main difference lies, however, in the material that they are crafted out off as well as the benefits these materials have to offer. They furthermore have different properties and, most importantly, different manufacturing costs. Aluminum tins are, for example, much stronger yet lighter in weight. On top of that, they are also cheaper to produce and recycle.
Metal tins were traditionally made out of tin, but nowadays aluminum has become the metal of choice. Both metals generally feature the same properties. There are, however, still some small but important differences. These differences are not that visible for the end-user, but they are of major importance to the manufacturers of these small metal containers.
Properties of Tin
The element tin is what we consider to be a low-melting crystalline. This sort of metal is malleable at room temperature making it easy to work with. The metal itself is extracted from cassiterite. This is a compound that exists out of tin and oxygen. This compound can be easily refined and processed, making tin an appealing metal to work with for can manufacturers. Another important reason why it is often used for cans is that tin does not corrode easily. Therefore, it allows you to store dry and wet materials alike without the content wearing down the metal food container.
Although tin can be found in many common every-day objects, the metal itself is not as common as it seems. In fact, scientists claim that only 0.0001% of the earth’s crust is made up out of tin making it one of the rarest “common metals” available. Due to this, modern tin cans are actually made from steel that has been finished off with a very thin tin coating. This layer has been applied to prevent the steel from corroding. That’s right; modern tin containers are actually not made from pure tin anymore as this would be unaffordable.
Properties of Aluminum
Aluminum is, just like tin, a metallic element. The main difference is, however, that aluminum can be more commonly found on our earth. In fact, its presence is abundant making up around 8.2% of the world’s crust. Aluminum is one of the most commonly found metals on earth, which results in lower prices.
Although it is easier to find, aluminum is a bit more difficult to refine due to the fact it is always found in different compounds. Usually, it is found on potassium aluminum sulfate or aluminum oxide. Therefore, different processes need to be applied to refine the aluminum. Although these processes were expensive at first, they have become increasingly more efficient and affordable. The recycling process of aluminum has furthermore developed tremendously over the past decades. As a result, aluminum has become one of the easiest and cheapest metals to recycle. Just like tin, aluminum is resistant against corrosion and easy to work with.
The Main Differences Between Tin and Aluminum
1, Aluminum cans are lightweight while tin cans are heavier.
2, Tin cans are more durable than aluminum cans.
3, Tin cans have higher corrosion-resistance properties than aluminum cans.
4, Aluminum cans have a more recycling efficiency than tin cans.
Tin Can Components Capacity
One of the primary considerations when selecting tin can components is their capacity. Evaluate the volume of solder you typically use in your soldering applications and choose a tin can with an appropriate capacity. It’s important to strike a balance between having enough solder readily available without excessive wastage or deterioration due to prolonged storage.
Tin Can Components Sealability
The sealability of tin can components is crucial for maintaining the quality and longevity of the solder. Look for tin cans with reliable sealing mechanisms, such as tight-fitting lids or vacuum-sealed packaging. A well-sealed tin can prevents moisture, air, and contaminants from entering, which can cause solder degradation or clumping.
Material Quality
Consider the material quality of the tin can itself. Look for cans made of durable and corrosion-resistant materials, such as high-grade metals or food-grade plastics. The material should be able to withstand prolonged exposure to solder and maintain its structural integrity over time.
Storage Conditions
Evaluate the storage conditions required for the tin can components. Some solder types have specific storage temperature requirements to prevent oxidation or degradation. Ensure the chosen tin can is suitable for the recommended storage conditions of your solder to maintain its quality.
Ease of Use
Consider the usability aspects of the tin can components. Look for cans with user-friendly features such as easy-to-open lids, convenient pouring spouts, or built-in dispensers. These features enhance the efficiency and convenience of accessing solder during soldering operations.
Why Are Tin Cans Used for Storing Food
A tin can is a thin metal container used for the distribution or storage of products. Many cans must be opened by cutting the "end" open; others have lids that can be removed. They may hold a wide range of items, including food, drinks, oil, chemicals, and so forth. Tinplate (tin-coated steel) or tin-free steel are used to make steel cans. Even aluminium cans are referred to as "tin cans" in some languages.
Tin cans are created by electroplating tin on iron and keeping food in them. Tin is a more reactive metal than iron. As a result, food does not come into touch with iron and is therefore protected against spoilage.
Steel cans are great drinking containers for a variety of reasons. Steel cans are more durable than cartons or plastic and less brittle than glass, preserving the contents during transportation and minimising leakage or spillage while also eliminating the need for supplementary packing. Metal cans without resealable closures are among the most tamper-evident of all package materials since they offer 100 percent barrier protection against light, water, and air.
Tin cans maintain and protect the product from light, oxidation, extremes of temperature, and contamination from the production to the ultimate customer, ensuring flavour, appearance, and quality. Steel-can food and drink have the same vitamin content as freshly cooked food without the need for preservatives. Steel cans also increase the shelf life of the product, providing for longer sell-by and use-by dates as well as less waste.
Tin cans do not require refrigeration in the supply chain as an ambient packaging medium, simplifying transportation and storage while saving energy and money.
Types of Tin Cans
Food Cans
Food cans are perhaps the most common type of tin cans, used for storing a wide range of food products such as fruits, vegetables, soups, meats, and beverages. These cans are typically sealed with airtight lids to preserve the freshness and flavor of the contents, making them ideal for long-term storage.
Aerosol Cans
Aerosol cans are pressurized containers used for dispensing a variety of products such as paints, adhesives, lubricants, and household cleaners. These cans are equipped with a valve and spray nozzle that allow for easy and controlled application of the contents. The sturdy construction of aerosol cans ensures safe handling and storage of pressurized substances.
Paint Cans
Paint tinc cans are specialized tin cans designed for storing and transporting paints, varnishes, and coatings. These cans are typically equipped with a resealable lid and a handle for easy carrying. The interior of paint cans is often lined with a protective coating to prevent chemical reactions and maintain the quality of the paint.
Chemical Cans
Chemical cans are used for packaging and distributing a wide range of industrial chemicals, solvents, and hazardous substances. These cans are designed to withstand harsh chemicals and prevent leakage or contamination. The tamper-proof design of chemical cans ensures the safety and integrity of the contents during storage and transportation.
Decorative Cans
Decorative cans are tin cans that have been specially designed for aesthetic purposes, such as gift packaging, home decor, and promotional giveaways. These cans may feature vibrant designs, embossed patterns, and custom printing to enhance their visual appeal. Decorative cans are often reused or repurposed for crafts and DIY projects.
Specialty Cans
Specialty cans encompass a wide range of tin cans that are used for specific purposes or industries, such as automotive products, healthcare, and pet care. These cans may include fuel storage cans, medication containers, and pet food packaging. Specialty cans are tailored to meet the unique requirements of their intended use, ensuring safety, convenience, and functionality.
Bead: Aconcave (interior bead) or convex (exterior bead) area that spans the circumference of the tin to add strength and stability to the tin body.
Body: Refers to the can without a lid; the bottom of a container.
Cover: The lid or closure of a can. It helps seal and secure food and beverage.
Curl: Asection of tin that has been turned in on itself to provide a safe, finished curved edge.
Distortion Printing: Printing technique used to create a drawn (seamless) tin in which artwork is intentionally distorted for printing on flat metal. The artwork is transformed into its intended representation as the seamless tin is drawn upward to form the container.
Dome: A cover with a flat horizontal surface (top) that tapers smoothly onto the skirt (vertical surface).
End: The end of a tin, also known as the bottom. Coffee-style hermetic tins have two ends, as opposed to cookie-style tins, which have one end and a cover. Ends can be attached by seaming or crimping with a machine known as a seamer.
Four-Color Process: (4/c) The use of four colours, cyan, magenta, yellow, and black, to create a nearly infinite spectrum of colours. The artwork is divided into four printing plates, and each colour is printed at a different screen angle to reproduce the original artwork on sheets of flat metal.
Full friction: A plug-style metal cap fits snugly against the can’s interior.
Hem: Atin area turned in on itself to provide a safe, finished flattened edge, similar to a curl.
Interior Seal: A cover/closure option in which a pliable ring fits inside a tin, allowing for a straight-sided slender profile can.
Layout: A two-dimensional drawing that depicts the exact specifications of a tin in its pre-fabricated (flat) state and is used to set up artwork to fit the can.
Lithography: Is a printing technique that uses flat metal sheets to create tin cans.
Lock-seam: Side walls meet and hook onto one another to form a tin body in a lock-seam. Many decorative tins are made this way because this seam style allows the printed area to meet at the seams.
Multiple friction: A plug closure fits into a “well” of a seamed-on ring, causing multiple frictions. When the plug is pressed into the ring, both surfaces (the outside and inside edge) make contact with the ring, resulting in multiple sealing surfaces on the plug/ring combination.
Pre-press: Laying the artwork for the tin can component before printing; includes proofing and creating films and plates for printing.
Slipcover: A cover/closure style in which the skirt (vertical surface) of the cover slips over and around the can body.
Stepped cover: A type of slipcover in which a “step” is created between the horizontal and vertical surfaces of the cover to allow for stacking tins with less risk of tipping over.
Varnish: Is a clear protective coating that is applied to metal. Varnishes come in gloss, matte, and stipple finishes. We only use FDA-approved varnishes that are safe for food contact.
