Retort packaging is a type of food packaging that is designed to withstand the high temperatures and pressures of the retort (or sterilization) process. It is commonly used to package low-acid foods such as meat, poultry, fish, and vegetables.
The retort process involves heating the packaged food to a high temperature (typically around 121-134 degrees Celsius) for a specific period of time, in order to kill any bacteria or microorganisms that might be present. This process ensures that the food is safe for consumption and has a long shelf life, without the need for refrigeration.
Retort packaging is sealed to create an airtight barrier that prevents contamination and keeps the food fresh. Retort packaging provides several benefits. It is a convenient way to package and preserve food, it can be used to update the product packaging, and it can be used to improve the product's shelf appeal. Additionally, retort packaging can be used to provide branding and labeling on the product, and it can be used to reduce the amount of packaging material used.
This type of packaging is commonly used for products such as canned goods, soups, sauces, and ready-to-eat meals. Retort packaging is also used in the food and beverage industries as well as in the military, camping and emergency food sectors.
