  • the slit closes and the contents are prevented from flowing out of the package.
  • the stiffness of the slit valve is sufficient to prevent the slit from opening under the hydrostatic pressure of the contents of the pouch in the absence of an external squeezing force.
  • the pack remains sealed between successive discharges of the contents.

  • the package may comprise an outer bag having gas-tight seals at opposite ends, and an inner pouch within the outer bag, wherein the inner pouch extends along the length of the outer bag and is secured to the outer bag only at the gas-tight seals, and wherein the inner pouch is maintained under sufficient tension by the pressure within the outer bag to suspend the inner pouch within the outer bag and to maintain a space between the inner pouch and the outer bag on all sides thereof.
  • the outer bag may be adapted to contain a substance capable of reacting with the contents of the inner pouch.

Materials to produce both the inner pouch and outer bag can each be tailored to the varied requirements of the products contained. A wide range of flexible packaging materials may be utilised. Particular examples of suitable materials are:
  • the package may allow the potential replacement of several current packaging systems offering product
  • the package uses air or an inert gas as the protective medium rather than rigid or semi-rigid constructions such as: glass, PET or PET bottles, aluminium cans
  • the packaging system may thus be environmentally friendly.
  • the packaging system may allow lower weight flexible materials to be tailored to the exact oxygen and barrier requirements of the product. It may be possible to enable significant reductions in the total weight of packaging material required and in the carbon footprint resource.
  • the package also offers the potential to use recycled materials in its construction and to use recyclable materials to pack many products. Some embodiments may enable continuous assembly of packages by modifying existing machines. According to another aspect, we provide an assembly comprising a
