Food packaging is in immediate contact with food, or is used to contain it from its production to final delivery to the customer. This packaging is used to protect the food from external influences, alterations, contamination and adulteration.
Its main purposes are protection, preservation and providing information such as best-before date, manufacturing date, batch number and nutrition facts. Health authorities typically describe the packaging as the container meant to ensure the preservation, transportation and handling of food products.
The main types of food packaging are glass containers, vacuum packaging, tetra pak containers, plastic packaging, tin packaging, cardboard packaging, wood packaging, long-life packaging, ice cream packaging, metal packaging, laminated packaging, and juice packaging.
