What is retort packing bag packaging? This is a can replacement method that involves the use of thin and flexible pouches. Producers need to fill, pack, and sterilize sealed containers, which can remove bacteria and extend the service life of products. The shelf life of the retort pouch food is similar to canned foods, so it does not need to be refrigerated.
The thin and flexible cooking bag can transfer heat quickly, resulting in sterilization process 30% faster than the can. This faster program uses less energy, so it can also save costs. Besides, it allows products to maintain high levels of vitamins, minerals, and other nutrients. The empty retort pouch for sale needs less storage space, so it reduces the storage cost to a certain extent. Cooking bag not only has the advantages of light weight, easy packaging after filling, transportation cost saving but also provides an expandable marketing space.
