Aseptic packaging - how it works

In order to ensure safe, shelf-stable food for over six months, both the packaging and the product must undergo sterilization prior to filling. There are two methods for carrying this out.


One option for aseptic filling involves passing flat, unformed packaging material through a hydrogen peroxide bath. Here, a concentration of 30% hydrogen peroxide is heated at 70°C for six seconds. Pressure rollers or hot air then eliminate the hydrogen peroxide from the packaging material.


Tetra Pak’s eBeam technology is another method for sterilizing packaging material. In this case, two eBeam lamps sterilize the inner and outer parts of the packaging material through the production process. Electron emissions guarantee an equivalent sterilization performance to that of hydrogen peroxide systems.


To prevent contamination, filling and sealing machinery must also be sterile before and during the packaging process. This can be achieved using hot air and steam, or by combining heat treatment with chemical sterilization.
