6-month shelf life of milk without preservatives! How is it possible?

The TETRA PAK packaging is a multilayer packaging which allows efficient storage of the product in it. The aseptic packaging and new technologies for processing milk at very high temperatures UHT (Ultra High Temperature) have revolutionized the food industry. Milk is packaged in an aseptic environment and is filled into pre-sterilized cartons made in an enclosed area. Boxes are sealed when optimally filled, which does not allow the content to be oxidized. And all this allows the 6-month shelf life of UHT milks with the brand My Day. This allows you to always have a spare carton of milk that can be stored in the kitchen cupboard (excluding days when the room temperature is over 24ºC).
