THE USE OF STEEL IN THE Packaging Industry
Packaging Industry
Steel cans used for food preservation can preserve high levels of nutrients and vitamins. Contrary to popular belief, canned fruits and vegetables do not use chemical preservatives but are preserved through high-pressure processing technology that kills bacteria. As an environmental packaging medium, steel cans do not require cooling in the supply chain, simplifying logistics and storage, saving energy and costs.
Steel packaging offers 100% barrier protection against light, water and air, making it the most tamper-resistant food packaging option available today. Steel cans can reduce waste by extending the shelf life of food. Additionally, the relatively high thermal conductivity means canned beverages cool much faster than glass or plastic bottles. Steel is used to package more than 1,500 types of food and beverages, as well as paints, health and beauty products, and household items.
1) Lightweight
positive impact on the environment by reducing the number of raw materials and energy required to produce them.
Most of the steel used in packaging is tinplate, which is coated with a thin layer of tin that functions as necessary for the production process. The tin layer is usually attached by electroplating.
2) Smaller Carbon Footprint
raw material extraction, processing, and manufacturing to recycling. However, steel cans are the best ecological performers because cans can be recycled over and over again. The recycling rate of steel packaging in some countries has reached more than 90%, and steel is the packaging material with the highest recycling rate in Europe.
The steel industry takes used cans and uses them to make new steel products. We can significantly reduce CO2 emissions by recycling steel tanks and closing the loop. Generally, we recycle steel tanks by melting them in electric arc furnaces or basic oxygen furnaces.
3) Magnetic And Recycling
empty cans to be transported during filling and packaging using a magnetic conveying system, improving accuracy and reducing potential spillage and waste.
In recycling facilities, steel cans can be easily separated from other waste using magnetic equipment, including cross-belt separators known as super-belt magnets and drum magnets.
Steel is a permanent material that can be recycled repeatedly without loss of quality. Recycling steel can saves the equivalent of a load of clothing, 1 hour of TV, or 24 hours of lighting (10W LED bulbs).
