1. What is a Retort Pouch?
The U.S. Army first proposed the concept of the retort pouches in 1950; the technology was first implemented in Italy. Retort pouches or retortable pouches are manufactured with multiple layers of composite materials, hence they are light and flexible. A retort pouch is a heat-resistant bag designed to withstand high-temperature sterilization (121°C-135°C/250°F+) while keeping food fresh.
2. Key Benefits of Retort Pouches
Many consumers may be unaware that foods and beverages are sterilized in the package prior to retail to ensure the product is sterile and safe for consumption and can be stored at room temperature on a shelf. Retort pouch refers to a container used for high-temperature food sterilization. Food sterilization involves the process of subjecting food, after filling and sealing, to a high-temperature sterilization device. Therefore, their quality requirement is very high. The material should be food-grade, resistant to heat, and should not release toxic substances during the retorting cook. There should not be any tearing or leakage in the case of cooking, and the pouch should be flat and wrinkle-free after cooking.
Traditionally, many brands have opted for metal cans to package goods in order to sterilize them. However, with the rapid increase in demand for flexible packaging and several advantages offered by the retort pouch, brand owners are increasingly shifting to this form of packaging.
