Q:The shelf life of the package usually takes several forms
Milk is extremely nutritious and therefore very perishable. In order to keep fresh and safe to consumers during circulation, the milk must be thoroughly sterilized and securely packaged. The sterilization method, compared with traditional pasteurization, the ultra high temperature sterilization (Ultra High, Temperature, UHT), can greatly reduce the milk color, flavor and nutritional value of the loss, and become the best and fastest way to the development of processing.

Carbonated drinks are mostly filled with carbon dioxide gas CO2, and its own drinks are carbon dioxide ingredients in the majority, with CO2 replacement of the air, but also for the preservation of the product, to ensure the taste, but also improved the shelf life.In addition, some food packaging is filled with a certain proportion of mixed gas, may be O2+CO2+N2, N2+CO2, O2, +CO2. This is also based on the needs of different enterprises, different customers.
Q:How to evaluate the quality of a food packaging bag design? From what angle?
Successful packaging must be consistent with the product positioning. Today's consumer groups are very different, for example, the elderly and young people on the acceptance of packaging design is very different, but also take moon cake as an example. The elderly may accept the traditional form of packaging (including graphic design, packaging design, structure design and so on) but the young people can accept the moon cake in the cake box, packed in ice cream box, metal box or even installed in the heavy metal in the punk style. You can't imagine an old lady in the supermarket, with a picture of a skull box filled with 8 pieces of moon cakes.

General milk packaging is basically Tetra Pak packaging or Kang Mei package, aluminum foil about 5% of the quality of the entire package, about 79% of the paper, polyethylene layer of about 16%. Because the aluminum foil, polyethylene layer and paper layer are bonded by hot pressing or adhesion, it is difficult to separate the layers.
