Retort pouches are widely used in the packaging of ready-to-eat foods, condiments, meat products, seafood, vegetables, and other foods requiring high-temperature sterilization. For example, pre-prepared meals, instant soup mixes, and canned food substitutes often use retort pouches for packaging, achieving commercial sterility through high-temperature cooking (typically 121°C, 15-30 minutes) and extending shelf life to 6-12 months. In addition, retort pouches are also suitable for the aseptic packaging of medical supplies and chemical products; their lightweight, easy-to-open, and microwave-safe characteristics are highly favored by consumers.
