Can making machine: Aluminum vs. plastic vs. glass

Can making machine: Aluminum vs. plastic vs. glass

can making machine is a designated machine meant to make cans. Can usually come in different materials; these include aluminum cans, plastic cans, and tin cans. Making these cans also involve different ways; for instance, tin cans can be achieved through lock seaming or welding. Processing industries use cans for packaging juices and soft drinks for easy storage and distribution. However, depending on the material, it has advantages and disadvantages including the impact on the environment.

Making a plastic can

The material used in making plastic cans is mainly PET. Like other plastics, PET is manufactured from non-renewable petroleum and is made up of long chains of carbons. PET products such as bottles are made through processes like stretch blow molding and injection method. In this case a plastic material is injected through molding and finally extruded using air pressure to achieve the desired shape.


A glass is made from non-renewable products such as silica, sand, and limestone. Compared to petroleum products, glass adds less environmental damage during extraction. During the manufacturing, high amount of energy is required of up to 1200 degrees Celsius to break down elements.

Aluminum Cans

On the hand, aluminum cans are made from elements like bauxite. It is mined through dredging mines or open-pit and they also have some damaging environmental impacts. However, about 40-70 percent of aluminum products are recycled. Unlike the aluminum virgin material, when content is recycled, it uses 90 to 95 percent less energy. While in glass bottles, about 75 percent of energy is saved when recycled.

A research done in the United States indicates glass bottles disposed of has a high environmental impact compared to aluminum cans. It also has climate change potential of about 23 percent. When you compare the three, PET plastic bottles have the lowest impact on global warming while the glass bottles and aluminum can have 40 and 23 percent potential on global warming respectively.


When it comes to weight, glass material weighs much higher than the other two materials. For instance, a middleweight PET bottle usually weighs 24g while a 335ml aluminum can weigh 11g. So taking into account the weight of transporting these materials, aluminum and PET bottles are more suitable.

When choosing a can making machine, you should first take into account the nature of the bottle you want. Some are rectangular, round bottom, and others have irregular shapes. Depending on your preferences, always go for the best that features automatic functionalities.

Comparison of Tin Cans and Aluminum Cans

Comparison of Tin Cans and Aluminum Cans

With the help of can making machine, production of tin cans has become extensively easy. This process goes through a series of tin can making machine production line that mostly has been integrated into one process. Normally the first step involves slitting process where the body, bottom, and the lid plates will be obtained. Then there is a can body making machine that operates automatically to make the body of the tin. Then top curling is done followed by necking, flanging and finally seaming.

The widely used cans are made of tin and aluminum. However, these two types do not have the same properties. Although most industries use them for general packaging process, they usually undergo different manufacturing process.

The inception

Tin cans were first used for storage purposes in the 1810s while the aluminum was introduced in 1965. These two types of tins have many uses, but the primary goal was to be used for preserving food products for local and overseas consumption. These two types protect food from the air and light. They are also durable and can be recycled.

Tin Cans

Tin cans are usually malleable at room temperatures because they are made up of the crystalline metallic element. They are extracted from elements like cassiterite, a tin compound and also oxygen. The refining process of tin makes it ideal for manufacturing. It does not corrode easily, and that is why it is useful for packaging food products. Some of the modern tin cans have steel coating and a layer of the tin to make it corrosion-resistant.


Aluminum is relatively cheap mineral element when you compare with other minerals. This is because they are available abundantly and makes up to 8.2% of the earth’s crust. However, refining aluminum is a bit complex as it has other compounds such as aluminum oxide or aluminum sulfate. Most of the cans made of aluminum are lightweight and robust.


One of the main differences between the two is the weight. The tin cans are relatively heavier than aluminum and are usually durable. They are resistant to corrosion making it ideal for foods that are acidic like tomatoes. However, when it comes to recycling, the aluminum cans are more efficient. You will save a lot of money when you recycle aluminum unlike when you refine the new ones.

When making tins, ensure that you buy a can making machine that is fully automated and integrated for ease of use.

Sign of Authenticity

While customers are shopping, they are very careful about the authenticity of the products. Psychologically, there are different ways that customers are able to identify this fact in the products by just looking. Packaging is one way that the customer is able to differentiate mediocre businesspersons from the serious one. If instance, if you are selling mints in tin can cans while your competition is using plastics, the customer is mostly persuaded to go for can packaged mints. That is another way that you can see your products sale rise.

Can Re-use

Another reason why can packaged product are likely to sell better than their counterparts the re-use of the cans. In most homestead, tin can are not through away after the product inside is finished. These cans find their back in the house and more the kitchen for storing condiments amongst other things. They can also be used for decoration or even sold for recycling. With that in made, the customer will more likely forego the plastic and other packaging options for tin cans. Therefore, if you have your products packaged in a tin can, the market will indirectly influence the demand for your products.

Product Safety

There are various types of can packaging in the industry including steel and aluminum. But all these alternatives have one thing in common- they can react the content of the package thus destroying. To avoid, some of the manufacturers adopt the process of coating the inside with a tin sheet. But such kinds of cans need a lot of care slight damage to the tin sheet can cause damages in food or packages product. But for the tin can, they do have such problems and wouldn’t damage the product even of the shape got deformed. Therefore, the packages are always 100 percent safe.

Benefits of Metal Cans Over Plastic Cans

Benefits of Metal Cans Over Plastic Cans

Historically, metal has always been used when designing parts of the needs to withstand the test of time. With the advancement of technology, some industries have tried to replace metal with plastics. Even though metal might not be the flamboyant material in packaging today, it is an indispensable product for both industries and consumers because its qualities cannot be found in any other materials. Below are some benefits of using metal cans instead of plastic cans.


Metal cans have been efficient in storage and preservation of food. They protect food from light and air, therefore, can be kept for a long time without getting spoiled. Using the tin can making machine, containers made of tin are heavier thus making them more durable and resistant to corrosive properties of acidic food.  Tin cans are often used to package food, while aluminum cans are more often used to package beverages like soda and beer. On the other hand, plastic cans have a short cycle period and therefore, less durable compared to metal cans.


Modern technology has led to a lot of advancement especially in the recycling of materials. Steel and aluminum cans are easy to recycle with no loss of quality, unlike plastics which must not be mixed. It is therefore difficult with plastics as it is impossible to tell the type of material by sight or touch. By recycling of these metal cans, it creates employment to those acquiring and selling scrap metals to the recycling facilities. It also reduces environmental damages caused by mining hence sustainable. That is not the same with plastic which loses value with every recycling.

Environmental impact

Plastic cans take a long time to decompose, and their photodegradation releases toxic chemicals into the surrounding environment. It becomes difficult for all people to adhere to the importance of recycling, therefore, increases garbage and consequently polluting the environment. Additionally, most plastic cans and bottles are thin and porous. Their quality lowers during the recycling process, meaning its value continues to decrease with reuse.

Metal cans, on the other hand, are cost-effective since one can reuse them without exhausting its value. They are also easily recycled since many of them are picked up by do-gooders and profiteers; moreover, metal cans can deteriorate through a natural process.


The raw materials that are used to make metal cans: aluminum and steel, are highly effective as opposed to plastics since they maintain their physical properties forever even after recycling into new products without losing their inherent properties. They are also sustainable as they require less energy to recycle thereby saving over 90% of energy that could have otherwise be used to manufacture cans from new materials. If you are using plastic, then you will not enjoy these benefits.

These are some of the major benefits of using metal packaging such as tin cans over the plastic. With glocal warming being as issue, can packages is the most eco-friendly packaing method that everyone should adopt. Metal packaging is also cheap in the longrun.

However, do not make a mistake or be tempted to buy low priced, inferior quality replacement parts. Get the best quality parts, and if possible, you should consider getting supplies from the original manufacturer or a reputable aftermarket manufacturer. That’s the best way that the quality of replacement parts can be achieved.

Guiding steps on the Proper Use of the Vacuum Sealer

Guiding steps on the Proper Use of the Vacuum Sealer

Owning a vacuum sealer will change kitchen life dramatically. Things get more comfortable as food wastage become a thing of the past due to the convenience of storage brought by the sealer. One can conveniently store the leftovers after preparing and serving the meal if the products used can be of help in the next meal. The vacuum packing machines also allow the storage of non-food items and therefore an essential home appliance. However, one has to know how to use it to achieve the best results, and this article provides some of the easy guiding tips.

These guiding steps are basic procedures that everyone using the vacuum packing machine, especially newbies, should know about. They are basic procedures that determine the overall effectiveness of the machine. Check out the following tips:

Freezing or Refrigerating Your Food

Although the vacuum sealer increases the life of the food stored in it, it is important to note that it does not fully inhibit food spoilage. In short, it does not work on its own but is used to improve the effectiveness of other food preservation machines such as freezers. It is therefore advisable to first freeze or refrigerate the food to maintain a lengthy period of freshness. After pre-freezing vacuum the food and freeze it for months or years.

Choice of Sealer bags

All types of vacuum packaging machine may have a common thing in their functionality. However, different types of sealers have different parts that may differ in size, shapes, and material among other qualities. Vacuum sealer bags are among the most crucial components of the sealer that determine their efficiency in storage. Most of these appliances are designed to only operate with specific bags, and therefore you cannot just use any bag from the market with your vacuum sealer. One has to obtain the recommended bag for the appliance, or otherwise, it fails to work correctly. Some of the faults likely to be witnessed include jamming of the bags inside the sealer or failure to seal correctly.

Freeze liquids Items

Vacuum sealing of liquids products requires much caution as it may result to spillage inside the machine that could interfere with its functionality. One should make sure that all liquids products intended to be stored in the sealer are first completely frozen. Failure to observe this may cause damage to the appliance when it sucks air together with the liquids or electrocution when retrieving the items.

Allowing the sealer bags some space

One mistake that some people do when vacuum sealing is bag overfill. It is advisable to let at least 3-5 inches at the top before sealing. This space ensures that one achieve a good seal and create a room for resealing in a situation where the first seal wasn’t done correctly.

Maintaining the smoothness of the bags

It is essential always to ensure that the sealer bags are kept smooth when filling with items to be stored. If the bags get wrinkles, they may form air pockets that inhibit attaining an airtight seal. Other than the smoothness of the bags, it is also important to make sure that the products being filled in the bags are smooth enough to avoid tearing. Sharp items such as boned-meat and frozen products can be wrapped with soft papers or towels before they are put in the bags.


One of the fundamental tricks to achieve the perfect functioning of the vacuum packing machine sealer and its long life is ensuring the cleanliness of both the appliance and the items being stored in it. Vacuum sealing of a variety of products in the machine on a daily basis will automatically leave it dirty. You, therefore, need to take a few minutes of your time to clean the sealer before sealing other products to remove particles such as crumbs that may have fallen. Otherwise, they may jam the sealer and prevent a perfect seal or cause contamination of food products stored in it.

These are the key guiding steps on how to vacuum seal food correctly. They should be followed strictly to get the most out of the machine. Otherwise, you will always have a problem with the food getting bad.

Tin Can Manufacturing Process

Tin Can Manufacturing Process

A tin can is a small container meant for storage and distribution of goods. Oftenly, most of the cans require removable covers while others require some cutting. Companies use cans for various purposes including storing food for sale, holding beverages, chemicals, oil among other uses. Tin can manufacture process involves multiple processes including seaming and fabrication.

The seaming process entails joining the can body and the ends through micro-seaming. There are various steps in this process which includes flanging the body with one of the cans end getting curled, joining the curled can and the can body. A can use maker machine for seaming operation consist of the closing station, base slate, seaming chuck,  and operation rolls. A base slate supports the body of the can while the seaming chuck holds the cover on the can body, but sometimes it can act as seaming roll pressure back up.

The modern micro-seaming process incorporates all the previous seaming except when re-dimensioning and re-designing the operation rolls. When re-designing the can, the level of hardness and thickness of the metal material is adjusted to obtain the desired length and size. There is also conventional seaming where the curves are designed and re-dimension of second operation rolls.

After completion of the first seam operation, operation roll is retracted, and it can no longer contact the can end. There is a micro-seam improvement that enables a user to obtain a tin can with substantial material savings.

Can Fabrications

There are several stages in can fabrication

  •    Formation of the tube and soldering the seams
  •    Joining the body with the bottom end
  •    Attaching labels and printing
  •    Filling the content
  •    Sterilization or retorting
  •    Joining the body with the top end

Commonly, double seaming is usually preferred when joining the ends with the body to prevent leakage. However, this process sometimes might deform the rims.

 Size and Material

Cans can be of different sizes and shapes, but the commons ones are the tuna tin and the soup tin. The walls of these cans are usually stiffened with bulges to help in resisting dents that might cause splitting of the seams. In most local dialects, all-metal cans are referred to as tin can although some are made from aluminium. Some of the cans are made using the tin-free steel, and in some parts like the UK, they produce foods that have a plastic coating to prevent acids corroding the can.

Can Making Machine

Can Making Machine

Making a tin can involves several steps that distinctively correlate with each other. These manufacturing processes include top curling, can body making, shearing/slitting, beading, seaming, flanging and many more. The primary material used by can making machine is mainly the tin plate. A slitting or shearing machine cuts the plate precisely until the required blanks are obtained with the desired length and width. These lengths should be able to fabricate into a single body during the final process.

The slitting process can be automated or done manually. Before you embark on this process, you should ensure the slitting machine works effectively depending on the necessity. There are three types of slitting machines namely:

  •    Manual slitting machine
  •    Semi-automatic slitting machine
  •    Fully-automatic slitting machine

Making Tin Body

There is a machine that is responsible for the body. This machine is programmed fully to incorporate various manufacturing processes at the same instance. This can machine usually does many tasks and can produce many can bodies in a short time interval. The steps incorporated during tin body production include pre-curling, making groove, notching, locking, and forming. All these processes have been integrated into one chain and operate in a synchronized manner.

Body making process should be done automatically to minimize the production cost. When you incorporate such mechanisms in your production line, you will be guaranteed to spent low expense regarding power consumption, space, maintenance cost among other issues. A tin body machine can also be adjusted to permit various sizes and shapes.

Top curling Machine

This is the can machine that is responsible for curling the top of the can. This will ensure the top part of the can have specific depression, and the can have the desired shape usually an excellent rim.

Beading machine

The beading machine is responsible for convex exterior and hollow interior area of a can. The can goes through a series of bulges and small depressions until the desired designed are obtained. The reason for beading in tin making process is to get a furnished can come with higher quality and stability.

Necking Machine

This machine is mainly meant to reduce or lessen the diameter or width of the can at the top. This necking process will ensure a narrow head is obtained that consequently makes the can look cool.

Seaming Machine

The bottom of the can is joined with the can’s body through the seaming process. This seaming machine can either do single or double seams depending on your preferences. However, the latter is usually preferred as it impeccably lasts longer and holds tightly.

Flanging Machine

The flanging machine is designed to make flanges on the top and bottom ends of the can. The edges are formed and flanges leveled at the two ends.

Lid Making Machine

Making a lid comprises several easy steps. There is trimming, edge curling, and punching from the blanks. Machines that have incorporated cutting-edge technology usually do the lid making process. At the inception, the blanks are punched precisely until the ideal lid is obtained with the desired shape and design.

Bottom Making Machine

Finally, there is a bottom making machine that punches the blank slits when making the bottom sections. The punched part is then seamed, and the can is the channeled through the sealing process.
