Pre-made food bagsGenerally, there are several packaging methods such as vacuum packaging, nitrogen-filled packaging, and retort pouch packaging.
Pre-made food bagsVacuum-packed.
Vacuum packaging is a kind of prefabricated food put into the packaging bag, by extracting the air in the packaging bag, to achieve the effect of sealing and preservation. This packaging method can effectively prevent oxygen from the air from entering the bag, thereby extending the shelf life of the prepared food. At the same time, vacuum packaging can also reduce the contact between food and the outside world and avoid food contamination.
Pre-made food bagsNitrogen-filled packaging.
Nitrogen-filled packaging is a kind of pre-made food that is placed in a packaging bag filled with nitrogen to isolate oxygen and achieve the purpose of extending the shelf life. This packaging method can effectively prevent the oxidation and deterioration of the food, while also maintaining the taste and nutritional value of the food.
Pre-made food bagsAluminum foil packaging.
Aluminum foil packaging is a type of packaging that uses aluminum foil as a packaging material. This packaging method can effectively isolate oxygen and moisture, thereby extending the shelf life of pre-made dishes. At the same time, aluminum foil packaging also has the advantages of high temperature resistance and corrosion resistance, and can adapt to various harsh storage environments.
Pre-made food bagsRetort pouch packing.
Retort pouch packaging is a packaging method that can withstand high temperature retorting. This packaging method can effectively extend the shelf life of pre-made dishes while maintaining the taste and nutritional value of the food. During the cooking process, you can directly put the retort pouch into the hot water to heat, which is convenient and fast.
The above are several common packaging methods for prefabricated dishes, and different packaging methods have different characteristics. When choosing the packaging method of prefabricated dishes, it is necessary to choose the appropriate packaging method according to the characteristics of the product and the storage environment.
