Shipping containers are large, sturdy boxes used to transport goods across oceans and land. They are designed to be easily loaded onto ships, trucks, and trains, making global trade more efficient. These containers come in standard sizes, which allows them to stack neatly and securely, maximizing space on cargo vessels. Originally made of steel, shipping containers can hold a variety of items, from electronics to food. Their durability protects the contents from weather and damage during transit. With the rise of e-commerce, the demand for shipping containers has increased, playing a crucial role in the supply chain of businesses worldwide, including Amazon and Walmart.
