Common can defects when using a can making machine

Common can defects when using a can making machine.

If you are working on a processing or manufacturing industry, you must have come through acan making machine. This machine is designated for making cans have different machines integrated together to form a continuous production line. The production line begins by slitting process where a plate is cut into blanks. These blanks are then used for making the can body. After the body is made, necking and beading are done. Finally, there is a seaming process that is very crucial in can production. Can seaming involve joining the bottom part of the can to the rest of the can and sometimes joining the lid with can body.

The processes of seaming involve different operations, and at every single stage, one should be careful as it affects the general shape of the can. There are single and double seaming; double seaming involves several layers mechanically interlocked together to form a seam. As much as this process is smooth, there several factors that has to be taken into considerations. These are:

  •    Conformity of the can body with the bottom or lid specification
  •    The nature of the seaming machine
  •    The condition of seaming rolls
  •    Lifter pressure and other components


A problem arises when one of these factors is not kept in check. These will result in seam defects that are very common when using a can making machine. These defects normally cause leaking of cans thus allowing the external contamination or reduce in shelf life. Here are some of the common defects in seaming:

  •    Cover vee- this is a projection of a seam just below the bottom of a normal seam resembling the v-shape.
  •    Cover droop- this occurs at the bottom of the seam below the double seam. It is usually a small projection.
  •    Cut over-this normally happens at the top of the seam that is inside and is sharp
  •    Dead head-also called spinner, it is caused by chuck spinning making the seam to be incomplete
  •    Knocked down flange- this is a defect that occurs when the body and cover hook do not interlock due to a bent.
  •    False seam-this is a portion of the seam that is not hooked.
  •    Long body hook-this is when the body hook exceeds the required specification.
  •    Long cover hook- this is when the length of the cover hook exceeds the required specification.

These and many more are some of the defects that are common when using a can making machine during the seaming process. Ensure that you keep the condition of the machine and use the correct material to avoid these common defects.

Advantages And Disadvantages Of Tin Cans

Advantages And Disadvantages Of Tin Cans

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.

How Are Tin Cans Common?

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 Can Advantages

  •    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 Can Disadvantages

  •   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

Tin Can History

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

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.

Types of Sealing Machines

Types of Sealing Machines

When looking for the best bag sealer that suits your preferences, you will note that they come in two distinct categories. There is impulse sealers and direct heat sealers. The option you will choose will solely depend on the nature of the bag you are using for sealing.

Direct Heat Sealer

This is a type of sealer that uses constant heat to seal the plastic bag. Direct heat sealing is more suitable for sealing materials that are relatively thicker. Most of the materials that are used in this process include poly cello films, gusset bags, cellophane, mylar, coated kraft papers and other thicker materials. Direct heating machines are usually hot, and extra caution should be taken when handling to prevent burns.

Impulse Sealers

This type of sealers uses impulses of electricity to heat up the sealing bag quickly. Once it seals the product, the impulse seal quickly cools to be ready for the next cycle. There are different types of these sealers, and the chance of getting burned is very minimal compared to direct heating. Thermoplastic materials are commonly used when using impulse machines. Other materials include the polypropylene and polyethylene. You can also use bags such as pilofilm, foil, padded mailers, kel-f, polyvinyl chloride, polyurethane among others.
Both the impulse and direct heat sealers come in different sizes and designs depending on the primary usage, volume and the size of the bags. Here are the most common types of sealers:

• Hand Sealers

These are sealers that resemble the L-bar machines and are portable. These sealers use impulse sealing technology and come in various sizes. You can carry them around and can handle bags of up to 10 mil thickness.

• Foot sealer

These are sealers that are meant for the continuous sealing process, and some parts need to be done manually especially when positioning bags. They usually have a food pedal that is connected to the sealing bar. When pressed, the sealing bar comes done, and the product is sealing. A foot sealer can utilize either direct heat or impulse sealing depending on what you are handling.

• Double impulse sealer

This is a good sealer that has two sealing bars, one at the bottom and the other at the top. This sealer can seal a bag of up to 20-mil in thickness and is ideal for heavy-duty applications.

• Sealer w/cutter

This is a type of sealer that can quickly seal a product and cut off the excess plastic in a single process.

6 Of the Most Common Types of Packaging Materials

6 Of the Most Common Types of Packaging Materials

Whether you are in the tech business, food industry, drinks manufacturing or you’re in the cosmetic industry, packaging is crucial. A good packaging should offer protection from any potential damage (leakage and breakage) that can deem the product useless. But packaging methods vary in every industry and depending on the nature of the product.  For instance, milk packaging material requirements would be different from cigarette packaging. Here are some of the common types of packaging:

Paper/Paper Board/Fiberboard

These are some of the most popular kinds of packaging materials due to their flexibility and versatility in use. Paper is widely used to make a range of thinner packaging products including paper bags, label, and butcher paper and so on. For the Paperboards, they are thicker and more durable than a standard paper. They are mostly used for cartons and boxes for packaging cereals, candy frozen foods and more. But for the fiberboard, they are more durable than both the paper and the paperboards. That is why they are used for the construction of corrugated boxes.

However, plastic has grown popular due to its flexibility and versatility in the packaging processes. Since paper are mostly made from the resin, it can be created to be rigid or flexible depending on the customer needs. They are also lightweight and easy to work with. It is such properties that have made plastic films the best alternative to cardboard and glass packaging.


  • Lightweight
  • Can be molded to limitless shapes
  • Impact resistant unlike glass
  • Heat Sealable


  • They are difficult to dispose of and thus a nuisance to the environment
  • Additives can contaminate some products
  • No absolute moisture and gas barrier


Foam may not be a typical packaging method like the rest, but it is very useful in the packaging on highly delicate products. The material is best known for its key properties such as good shock absorbing. Some of the delicate products include furniture, glass, TVs and anything else that may have sharp edges. However, foam cannot work alone. In most cases, cardboards and plastics films are used to encase the product and that foam. That ensures that all stays compathe ct while on transit.


  • High shock absorbing properties
  • It is recyclable


  • Cannot be used alone
  • A little bit expensive compared to other materials.

Aluminum Packaging

Aluminum packaging or what is commonly referred to as tin cans have been used for decades but has gained tremendous growth in the recent times. Most of this increment in demand can be attributed to the growing awareness of environmental degradation caused by plastic and wood materials. Whereas plastic has proven difficult to dispose of, wood materials have caused massive destruction of the forest cover. Aluminum package is proving to be the solution to such environmental damages. That is why the demand for tin can making machines has increased in the recent years. In fact, it has been proven that 7 billion foil cans and containers are being produced annually.


  • Versatility- can be used for packages food, medical, beverages, cosmetics products and so on.
  • Offers moisture, sunlight, gas and other thermal elements protection
  • Tin cans can be recycled.
  • Can makers machines are easy to operate thus production is easy


  • Aluminum is a non-renewable resource
  • Corrosion may destroy products

Tin Packaging

Demand for tin as a packaging material/method has soared in the last few decades. Tin cans are popular with food processing, beverage, cosmetics and pharmaceutical industries since the can preserve products for a very long period.  In the food industry, they are mostly for packaging oils, soup, fruits, ready meat, fish, and vegetables and so on. Unlike aluminum, tin is not corrosive, and thus the nutritional value of food is retained.  In addition can Tin can are easy to transport compared to the alternative can products in the market. They are not complicated make where a small tin can making machine can thousands of cans in a day.


  • Versatility in use- can be used in a range of industries.
  • Offers moisture, sunlight and gas protection
