What is retort packaging?
Retort packaging is a sterilizable packaging format—most commonly pouches, trays, and cups—constructed with thin, bonded layers that can withstand thermal processing at approximately 120°C (or higher) to achieve commercial sterility. Products are cooked or sterilized inside the sealed container, enabling long ambient shelf life. Compared with cans or glass, retort pouches are lightweight, compact, and reheat quickly (boiling water immersion or microwave), aligning with on-the-go consumption.
