The World of Cans

What is a Can?

A can is a container typically made of metal or aluminum that is used for storing food and beverages. Cans are known for their durability, lightweight nature, and long shelf life, making them a popular choice in both households and industries.

History of Cans

The use of cans dates back to the early 19th century. The first patented can was created by Peter Durand in 1810. It was initially used for preserving food during long sea voyages. The first use of canned goods in the market included vegetables, meat, and even seafood.

Types of Cans

Cans come in various shapes and sizes, tailored to suit different types of products. The most common types include:

• Metal Cans: Typically used for beverages, sauces, and vegetables.
• Aluminum Cans: Lightweight, usually for sodas and beers.
• Steel Cans: Known for their strength, commonly used for foods and oils.
• Paint Cans: Used for storing liquid paints and coatings.

Uses of Cans

Cans are extensively used for:

• Food preservation: Canning is a method that seals food within cans to protect them from exposure to air and bacteria, extending their shelf life.
• Beverage packaging: Soft drinks, beer, and juice are commonly sold in cans due to their convenience and portability.
• Non-food products: Cans are also used to store items like paint, oils, and pharmaceuticals.

Environmental Impact

Cans can be recycled, making them a more sustainable option compared to other types of packaging. Recycling aluminum cans saves 95% of the energy required to produce new aluminum from raw materials. As a result, recycling programs have been instituted globally to reduce waste and promote the use of reusable materials.
