Roll-fed packaging material is sterilized and shaped into a tube.
The tube is filled with the product and the packages are shaped
and sealed below the surface of the liquid. This means that
there is no air space in the package.
In the aseptic packaging process the product passes from the
UHT (Ultra High Temperature) treatment in a closed system to
the packaging machine. There it is packed under aseptic
conditions in a packaging material, which is sterile and keeps
out light and air.
Sterilization of the packaging material is made in a bath of
hydrogen peroxide. Any residue is removed with heat. This
leaves the packaging material completely dry and creates a
sterile atmosphere in the filling section.
