Retort packaging is a type of food packaging designed to withstand high temperatures and pressures during the sterilization process. Typically made from multiple layers of materials, including plastics and aluminum, it provides a barrier against moisture, oxygen, and light, ensuring the safety and longevity of the food inside. This packaging method is commonly used for ready-to-eat meals, soups, and sauces, allowing for extended shelf life without the need for preservatives.
