Some are automated and requires less labor compared to others.

Comparison between tin cans and PET bottles

For beverage and food products packaging, industries and individuals usually use tin or PET bottles. Tin cans are made using the can making machine while the plastic bottles are made using PET blow molding machine. The common similarity is that both these products can be used to carry liquids, but the difference comes in the production process and the effects on health and the environment.

Production process

The tin can making machine production line usually involves a series of process. First, is making the body part, this can be through slitting or shearing the plate to make blanks that are used for body making. Then the lid is made and the bottom plate. The blanks are then subjected into the can body making machine that is automatic to produce the desired body. After that, top curling and necking are done before flanging and seaming process. Depending on the can making machines, these processes can be integrated into one.

On the other hand, making PET bottles also involves a series of process. Different machines can be used in this case. This includes stretch blow molding machine, injection molding machine, and extruding molding machine. You can choose one of the machines depending on the size and nature of the bottle you want to make. For instance, in stretch molding, the parison is blown using pressurized air and stretch to form a container with the desired shape.


The sizes

The amount standard plastic bottle can hold is 20 oz while most cans hold about 12 oz. on the other hand, most PET bottles can provide about 2.5 servings while the cans only offer one serving. Products like coca cola are usually available in both bottles and cans. Most of the larger servings are of cans because once you have sealed it, you cannot reseal it.  

Advantages of tin cans

Metal cans don not have bisphenol-A component that is usually found in plastics. This compound has a health risk, and sometimes it can cause cancer. Although most consumers claim they the plastic bottles are safe, BPA compound is usually present. However, some manufacturers remove generally BPA in their containers before using them.


Advantages of PET bottles

A PET bottle is made up of long chain molecules that are less reactive and has a high melting point. These bottles are usually clear and are good when you want to display your products to the consumers. They also add no strange taste to the product and are portable.


In recent years, people have had the adoration of illicit relationship with tin cans. This is because tin has inherent qualities that make it great for packaging products. These cans are produced by can making machine and are not only used for food products, but they are also common for packaging drinks, promotional, household and industrial products.


One of the can manufacturing institutes asserts that steel cans are used for more than 1,500 food products around the world. This is a genuinely remarkable number when one considers how much food is expended each month in a country like China and the United States alone. For instance, the U.S. Registration Bureau reports that $389 million dollars worth of sustenance stuff in the retail and nourishment administrations industry was sold amid April of 2011. This is a considerable measure of nourishment, and most of these products are packaged in cans. And keeping in mind that tin cans are additionally convenient, they are likewise an asset that can be effortlessly reused.


•    Tin products are up to 100% recyclable if discarded effectively.

•    They are the most impact-resistant form of storage right now in the market.

•    In 2006, a greater part of tin and steel cans were used, and around 28% was reused.

•    Recycling tin and steel cans can spare millions of money in energy costs each year.

•    Waterproof

•    They are cheap when you compare with other metals


• Tin cans are non-inexhaustible resources. Once produced, they cannot replenish. Because of this, the customer must ensure these cans are reused and repurposed.

•   About 34% of the tin cans are discarded instead of reused.

• Unless the empty cans are appropriately discarded and added to the shut circle reusing process, tin cans could, in the end, run dry.

•    It can rust

•    Sometimes it is expensive to recycle


Napoleon Bonaparte’s campaign during the nineteenth century started nourishment packaging solutions when he offered a reward for any individual who could figure out how to safeguard food products for his hungry troops. In 1810, Nicholas Appert managed to win 12,000 francs from Napoleon when he came up with a technique of storing food products in glass containers. Also in the year, Peter Durand licensed an outline for iron can with tin plating and lead fastening. Quick forward 100 years to 1922: the procedure of can pleating was acquainted with a tin can production and by the mid-1950s, tin cans never again used lead weld.

Disadvantages of metal packaging

In the 21st century, life has drastically changed due to its versatility and universal consumer approval. The metal packaging though being in the market for a long time, with the changes of the market trends, the industry is constantly on the move to research and innovate more of the sizes and designs convenient to meet the needs of increasingly demanding customers. Metal cans which are made of by mostly steel, aluminum or tin are a great asset and investment when it comes to storing and protecting food and also beverages for a long period. Metal containers, made with the aid of a can making machine, have a great advantage over other packaging methods because of its durable, resistance to high temperatures providing stability during processing. However, this method has a few disadvantages that are discussed below;


Steel is vulnerable to corrosion which causes the metal to deteriorate. If you find rust in the can, it is one example of corrosion. This affects the quality and also will bring about an adverse effect on the food packed inside and mostly would make food go bad. This cans can only be coated with polymers to prevent corrosion. However, tin cans are highly recommended since they are less prone to corrosion.

Aluminum and acidic foods

The corrosion of soft drinks in aluminum cans is a big challenge that the industry is facing and usually that results in loss of money. It is also important that metallic elements in food can cause severe health complications. Acidic foods such as tomatoes can be greatly affected by aluminum if the metal is used to store them. This ends up ruining the taste and quality of the food. However, tin cans could be a great alternative since the material is not affected by food acidity.

Content not visible

Most canned food is already sealed and therefore it’s hard for anyone to see whatever content is inside. This becomes hard for one to make a right choice since you may pick a can that has content that is not the desired one and this poses a significant challenge to the consumers. They sometimes prefer other packaging materials such as plastics in some situations where one needs transparency.

Metal is moderately heavy packaging material

Compared to other methods of packaging such as plastic, steel is heavy.  That is why it is more durable than other metals used in the packaging of foods. However, that means that it is quite expensive due to its construction process. That makes these cans expensive depending on quality of the material that is used. Therefore, you will be spending more in this method of packaging.

Multi-step cans manufacturing process

Manufacturing of metal cans involves several procedures in the production line and several input materials.  It also involves different machines that makeup the can making machine such as the seaming machine, slitting machine among others. There is also the need for a sealing machine to seal them, therefore, a lot of time taken in this process.

Tin packaging vs. PET packaging

PET cans made by PET stretch blow molding machine and Tin cans made by tin can making machine are widely used for packaging purposes. For instance, PET alone covers up to 30 percent of all beverage packaging, unlike tin cans that are about 16 percent. PET nowadays are technology and consumer driven, the versatile nature of this material makes it ideal for multiple drink applications. On the other hand, tin cans are made using a can making machine production line that involves several processes integrated into one.

Tin Cans

While PET may have the played a more significant part in drinks packaging, tin cans keep on representing an expansive bit of the food products, brew, soda pops, and spirits markets. Of 1.250 trillion packaging units, tin records for 17% out of 2015, which has dropped to 16% of 1.419 trillion units in 2018.

Various patterns are influencing the material choice for packaging. One is item differentiation; this is a noteworthy driver in packaging. This includes metal cans that can be fabricated into different shapes and sizes using can making the machine. The use of unique shapes also encourages marketers to reposition an item from ordinary to premium level to help justify the higher packing costs. Apart from the packaging’s shape, other important distinctions for an item can be made through printing, marking and other design techniques.

Recyclability and supportability are among the real trends influencing the worldwide market of tin cans. All inclusive, tin refreshment cans have a rate of collection of around 70%, which is more than twofold that of some other drink cans. Furthermore, in recent decades, tin cans have turned out to be impressively lighter. Enhancements in can-production innovation and the nonstop advancement of tin evaluations have made conceivable the down-gauging of cans in the can-production process. The decrease in weight is advantageous as it reduces the amount of waste.

PET packaging

On the other hand, PET containers are commonly used in drinks such as mineral water and other non-carbonated drinks. This is because they are efficient, light, safe, transparent and recyclable also. For some products, the taste and purity are very crucial. In such case, PET materials are normally used as they are made up of long chain molecules that are less reactive and have a high melting point. Due to pollution issues, PET materials are usually collected and recycled back. Also, there is growing use of PET packaging as it adds resource reduction in the supply chain, especially during distribution.

Depending on the nature of your industry, the production cost and the type of your product, you should always go for the material that suits you.

The Process of Can Manufacturing

A can is a small container that is used for storage and distribution of items. In most of the times, the cans need to have removable covers for retrieving the products while others may be enclosed in such a way that they have to be cut open. Cans are often used for industrial purposes such as storage of product meant for sale or holding beverages, oil, chemical among other several uses. The process of manufacturing cans, aided by can making machine, is not a complex one but involves processes such as seaming and fabrication.

There are numerous steps involved in tin making and must follow each other strategically to achieve a perfect can. They include the curling of the top, body making, slitting, seaming, flanging among others. The primary material is the tin plate, and the slitting process cuts it into precise size and shapes. The combination of these steps results in an end product which is the desired can.

Slitting or Shearing

The first in the can making process is cutting the blanks in various sizes. The packaging can are often made in different sizes and shapes to fit the requirements of the customers. The tin can-making machines, therefore, contains structures that allow altering of shapes and sizes of the cans as demanded. The common types of tin cans produced in large quantities include mint tin and soup tin. The walls of the tins are stiffened with bulges to avoid dents. Cans are usually made from tin aluminum or can be coated with tin depending on the content packed in them. Once the blanks are cut in right sizes, process of can body making begins.

Can Body Making

Once you have the right sizes for your machine, the next step is can body making. Depending on the kind can making machine production line you are using, the entire can body making should fully automated. Where the blanks are folded to for the actual shape of the tin.


The process of seaming involves the integration of the can body with the bottom and top lid. Several steps such as flanging are part of this process. One end of the can which is undergoing curling is flanged with the body of the can, and then they are joined. The can making machine that conducts this process has various components which include a closing station, seaming chuck, base slate and the operation rolls. However, seaming process depends on the can maker machine that you are using.


Fabrication process has a number of stages that are involved. These include the formation of the cylindrical form from the plate and then soldering of the seams. It then follows the integration of the can body with the bottom end. What comes next is the attachment of the labels and then their printing to include the details of the content inside. After this, the blank can is filled with the desired content. For preservation purposes, sterilization or retorting is conducted before the final step is carried out which is the joining of the body with the top lid.
