Abstract: Described herein are RFID structures and methods of manufacturing RFID structures. An antenna substrate is provided. A first stack layer is provided. An antenna assembly including an antenna track, and at least two contact pads, are formed on a first surface of the antenna substrate. An integrated circuit unit is coupled to the at least two contact pads. A first surface of the first stack layer, the first surface of the antenna substrate, or both are coated with a unidirectional thermally expansive coating material. The first surface of the antenna substrate is positioned to be adjacent to the first surface of the first stack layer.

Abstract: A sealed package comprising a container, intended for use or reuse as a drinking vessel, and a cover. The container has a cylindrical surface adjacent its mouth to receive a length of tape which, on one side, carries a layer of pressure sensitive adhesive, which can be peeled from the container without leaving objectionable residues. The tape carries a layer of heat-sealable material on its opposite face and this is heat sealed to an aluminium foil lid, also bearing a coating of a heat sealing material.

Abstract: A service unit capable of supplying sterile utilities including compressed air and water and preferably both hot and cold water, disinfectant and suction, is particularly adapted to be connected to machines for the packaging of foods, medicines and the like under aseptic conditions to provide servicing utilities. The service unit has the advantage of being capable of supplying sterile utilities to such aseptic packaging machines from outside the aseptic screen surrounding the packaging workspace and thus to be capable of providing sterile services to several packaging machines in turn.
