Abstract: A packaging material is provided including a substrate, and an oxygen transmission inhibiting layer that is carried by the substrate. The oxygen transmission inhibiting layer is formed of a composite material including a linear polysaccharide medium within which one or more additives are dispersed. The composite material is capable of forming a substantially continuous film to provide a barrier to transmission of oxygen gas. The oxygen transmission inhibiting layer is configured within the packaging material at a thickness that is efficacious in inhibiting the transmission of oxygen gas therethrough. A packaging device has two or more component parts, at least one of which is formed of the packaging material. The component parts of the packaging device are shaped and/or configured to be assembled to define an interior region within which goods are to be contained.

Abstract: A method is provided of applying a coating material to a concave surface of an article that has a rim around the concave surface, and a cavity between the concave surface and the rim. The method includes discharging coating material in a liquid form into the cavity, extracting a first amount of the discharged liquid coating material from the cavity, thereby leaving a residual amount of the liquid coating on the concave surface within the cavity, and maintaining the article in conditions appropriate to allow the residual amount of liquid coating material to cure on the concave surface.

Abstract: A process for forming a pre-form for a moulded pulp fibre product involves providing a porous mould that has one or more pre-form mould portions that each have an outer surface corresponding to a surface of the pre-form. Pulp fibre slurry is discharged from an outlet; each pre-form mould portion is coated with discharged pulp fibre slurry by moving the porous mould relative to the outlet. Thus, a slurry deposit for the pre-form is formed on the outer surfaces of the pre-form mould portions. Fluid from the slurry deposit is extracted through the porous mould to form the pre-form.

Abstract: A tool for a thermoforming process to form a moulded product from wet pulp fibre material includes two or more moulds each having a moulding surface, an actuator assembly, and a fluid extraction system. At least one of the moulds is displaceable by the actuator assembly between first and second positions and has fluid extraction paths extending through the mould to transport fluid away from the moulding surface. One of the moulds has a first layer that is substantially rigid to form a support member and is in communication with a heating subsystem of the fluid extraction system, and a second layer that is, in use of the tool, between the first layer and the wet pulp fibre material. The second layer is formed of a material that has interconnected internal voids forming part of the fluid extraction paths and has a lower heat transfer coefficient than the first layer.

Abstract: A moulded pulp fibre product and a method of forming a moulded pulp fibre product are provided. The method involves forming two or more pulp fibre pre-forms that each include at least one mating surface. Each pre-form is made from a suspension of pulp fibres in liquid. The pulp fibre pre-forms are assembled into a set in which adjacent pulp fibre pre-forms have mating surfaces that are in contact with, or adjacent to one another. The set of pulp fibre pre-forms are then bonded to form a pulp fibre laminate.
