Steel Packaging

 

Steel Can
The steel can was invented more than 200 years ago.

Cans were first used as containers for food during the Napoleonic wars. The idea for preserving food by heating it in containers was developed by Nicolas Appert. He used glass jars, which were sent to French troops on the Russian front. In 1810, British merchant Peter Durand was granted the patent for a method of preserving food and other perishable items using vessels made of various materials, including steel.

Not surprisingly, food safety is still one of the most important benefits of canned food packaging.

However, food storage is only one of the many applications of steel packaging.

Steel packaging is durable, tamper-resistant and convenient. It is also ‘shelf-stable’, meaning that it can protect the contents from deterioration for a long time. In addition to these attributes, the steel used in packaging also has an aesthetic function. After all, packaging is designed not only to store the product but also to advertise it to the consumer.

An industry built on innovation

In some countries, steel cans are also referred to as tin cans or simply tins. There are thousands of applications, from the familiar soft drink can to unusually-shaped paint tins that are easy to hold in one hand and retro designer biscuit tins. Steel packaging is used for:

  • Food
  • Beverages
  • Promotional materials
  • Aerosols
  • Paints and chemicals
  • Bottle tops and caps

The majority of steel used in packaging is tinplate, which is steel that has been coated with a layer of tin to prevent corrosion. Although tinplate only accounts for around 1% of steel production, it is a highly visible and dynamic industry. Brands and products compete for consumers’ attention on the shelves of supermarkets and other retailers.

The manufacturing processes used in steel packaging are high-tech and sophisticated. Commercial production began in 1812, in a canning factory near London that supplied food to the British army. In 1846, cans were manufactured at the rate of 60 an hour. Modern can-makers can produce up to 1,000 cans a minute.

Once the steel is coated with tin, the tinplate can be coated with polymer, lacquered and printed. The final result is an attractive, safe and functional product.

Highly recyclable

Steel holds a unique position as a sustainable packaging material because it is 100% recyclable. Steel cans are the most recycled form of packaging. A significant proportion of all the steel in a can comes from recycled sources.

Steel The Green Option

The figures by APEAL, the Association of European Producers of Steel for Packaging, indicate that in 2012, 2.7 million tonnes of steel packaging were recycled, corresponding to an average European rate of 74%. This reinforces the long-term trend for steel as the most recycled packaging material in Europe.

Steel packaging’s recycling rate has increased threefold over the last 20 years and steel remains the most recycled packaging material in Europe. Plastic, beverage cartons, aluminium and glass have rates of 35%, 39%, 68% and 70% respectively (source: APEAL).

Alexander Mohr, Secretary General of APEAL, commented: “While steel maintains its position as the most recycled packaging material in Europe, it is clear there is still some work to be done in order for the industry to hit its vision of 80% recycling rate by 2020.”

According to the Steel Recycling Institute, for the US, the overall recycling rate for steel in 2012 was 88%, with nearly 84 million tonnes of steel recycled. This included the more than 1.3 million tons of tin plate steel – the equivalent of 21 billion steel cans, which were recycled at a rate of 71%, the highest among packaging materials.

“The steel industry’s internationally-recognised energy efficiency, coupled with the recycling rate that is the highest of any material, proves our commitment to sustainability and resource conservation,” said Thomas J. Gibson, president and CEO, American Iron and steel Institute.

Steel products naturally contribute to resource conservation through their lightweight potential, durability and recyclability. Steel is 100% recyclable. It can be infinitely recycled without loss of key properties, ensuring that the resources invested in its production are not lost and can be infinitely reused. Steel recycling accounts for significant raw material and energy savings.

Due to its magnetic properties, steel is easy to separate from waste streams, enabling high recovery rates.

Recovery rates differ from recycling rates. For example, about 85% of automobiles are recovered for recycling, and nearly 100% of the steel in these recovered vehicles is recycled. More than 1,400 kg of iron ore, 740 kg of coal, and 120 kg of limestone are saved for one tonne of steel scrap made into new steel.
Table 1: Post-consumer steel product recovery rates by sector – worldsteel estimates

Sector Recovery rate 2007 (%) Recovery 2050 (%) Life cycle in years
Construction 85% 90% 40 to 70
Automotive 85% 90% 7 to 15
Machinery 90% 95% 10 to 20
Electrical and domestic appliances 50% 65% 4 to 10
Weighted global average 83% 90% N/A

 

Steel is the most recycled industrial material in the world, with over 500 Mt recycled annually, including pre- and post-consumer scrap. Over 22 billion tonnes of steel has been recycled worldwide since 1900 owing to steel’s 100% recyclability.

What’s Your Type?

Uncategorized

Shanghai Metal Corporation (SMC) focuses on four main types of steel. The committed team at SMC want to know what is your type? If you’re new to the stainless steel family do not stress here is a quick overview.


Ferritic


Ferrite

These steels are based on Chromium with small amounts of Carbon usually less than 0.10%. They have a similar microstructure to carbon and low alloy steels. The lack of toughness limits the use to relatively thin sections as a result of lack of toughness in welds. However, where welding is not required they offer a wide range of applications. They cannot be hardened by heat treatment. High Chromium steels with additions of Molybdenum can be used in quite aggressive conditions such as sea water. Ferritic steels are also chosen for their resistance to stress corrosion cracking. They are not as formable as austenitic stainless steels.


Austenitic


Austenite

These steels are the most common. Their microstructure is derived from the addition of Nickel, Manganese and Nitrogen. It is the same structure as occurs in ordinary steels at much higher temperatures. This structure gives these steels their characteristic combination of weldability and formability. Corrosion resistance can be enhanced by adding Chromium, Molybdenum and Nitrogen. They cannot be hardened by heat treatment but have the useful property of being able to be work hardened to high strength levels whilst retaining a useful level of ductility and toughness. Standard austenitic steels are vulnerable to stress corrosion cracking. Higher nickel austenitic steels have increased resistance to stress corrosion cracking. They are nominally non-magnetic but usually exhibit some magnetic response depending on the composition and the work hardening of the steel.


Martensitic


Martensitic

These steels are similar to ferritic steels in being based on Chromium but have higher Carbon levels up as high as 1%. This allows them to be hardened and tempered much like carbon and low-alloy steels. They are used where high strength and moderate corrosion resistance is required. They are more common in long products than in sheet and plate form. They have generally low weldability and formability. They are magnetic.


Duplex


Duplex

These steels have a microstructure which is approximately 50% ferritic and 50% austenitic. This gives them a higher strength than either ferritic or austenitic steels. They are resistant to stress corrosion cracking. So called “lean duplex” steels are formulated to have comparable corrosion resistance to standard austenitic steels but with enhanced strength and resistance to stress corrosion cracking. “Superduplex” steels have enhanced strength and resistance to all forms of corrosion compared to standard austenitic steels. They are weldable but need care in selection of welding consumables and heat input. They have moderate formability. They are magnetic but not so much as the ferritic, martensitic and PH grades due to the 50% austenitic phase.
