  • UHT ultra-high-temperature treated milk
  • wine tomato sauce
  • etc. are sold in packages made of sterilized packaging material.
  • a typical example is the parallelepiped-shaped package for liquid or pourable food products known as Tetra Brik Aseptic (registered trademark) , which is made by folding, sealing and cutting a web of laminated packaging material.
  • the packaging material has a multilayer structure comprising a base layer, e.g. of paper, covered on both sides with layers of heat-seal plastic material, e.g. polyethylene.
  • the packaging material also comprises a layer of oxygen-barrier material, e.g. an aluminium foil, which is superimposed on a layer of heat-seal plastic material, and is in turn covered with another layer of heat-seal plastic material forming the inner face of the package eventually contacting the food product .
  • Packages of this sort are normally produced on fully automatic packaging machines, on which a continuous tube is formed from the web-fed packaging material; the web of packaging material is sterilized on the packaging machine, e.g. by applying a chemical sterilizing agent, such as a hydrogen peroxide solution, which, once sterilization is completed, is removed from the surfaces of the packaging material, e.g. evaporated by heating; the web so sterilized is then maintained in a closed, sterile environment, and is folded and sealed longitudinally to form a tube, which is fed vertically.
  • a chemical sterilizing agent such as a hydrogen peroxide solution
  • the tube is filled with the sterilized or sterile-processed food product, and is sealed and subsequently cut along equally spaced cross sections; pillow packs are so obtained, which are then folded mechanically to form respective finished packages at a final folder.
  • crease lines i.e. weakening lines
  • the crease lines define folding lines along which the pillow packs are folded to take the desired final configuration .
  • the packaging material may be cut into blanks, which are formed into packages on forming spindles, and the resulting packages are then filled with the food product and sealed.
  • a type of package is the so-called "gable-top" package known by the trade name Tetra Rex (registered trademark) .
  • the removable portion is formed on the packaging material prior to folding and sealing the packaging material to form the finished package.

  • the top portion of the finished package may include a flat and horizontal top panel, parallel to the bottom panel; alternatively, slanted top panels are very conveniently used in combination with opening devices because they are wider than corresponding flat top panels of parallelepiped or prismatic packages and therefore allow the application of larger opening devices, e.g. provided with screw caps or the like.
