  • the invention relates to a casing for transporting food or beverage product, the casing being characterised in that it comprises:
  • a side panel part comprising at least two side panels, each side panel comprising a peripheral free edge and a sealing margin along the peripheral free edge, and
  • one band made from one sheet, a comprising a sealing area, the sealing area of the band being sealed to the sealing margin of both side panels, forming a flange extending outward.
  • sealing designates any closure means configured to link two elements one to the other, in order to provide an airtight bond, including for example gluing, soldering or welding.
  • Airtight bond is a bond between two elements that does not allow air to cross through.
  • This airtight bond can be quickly tested using a ‘bubble bath test”:, the casing is fully immersed in a water tank in which a vacuum of approximately -300mbars is applied.
  • WVTR Water Vapor Transmission Rate
  • the principle is to expose the casing to a tracer gas in a chamber and to insert (in a tight way) a sensor through the wall of the casing and to measure over a certain time the evolution of the quantity of the tracer gas going inside the case (from the chamber full of tracer gas inside the casing)
  • the invention thus allows to protect products included in the casing from oxygen, moisture, humidity and/or other external possible aggressions, while also offering a mechanical shield to protect the products from impacts, vibrations or other constrains occurring along the life of the products.
  • the casing is made out of a minimum of parts that are assembled together with a minimum of junction areas aiming to reduce any potential leakage.
  • the band thus surrounds both side panels.
