A can is a simple metal container designed to protect its contents against weather and nature. It is rigid, unbreakable and requires no special handling precautions. Cans are commonly used to package a variety of products such as carbonated beverages, freshly harvested fruits, vegetables, meats, fish and ready meals. They guarantee uniformity of product quality and give us access to a variety of nutritious foods beyond their growing season, even internationally, all year round. Canning has become an essential part of modern society and plays a significant role in the economy, providing jobs and contributing billions to the U.S. economy.
