This invention relates to a method of manufacturing a food packaging container 10 made from sugar cane pulp or bagasse and having a polymer liner on an internal face of the container or tray 10, an apparatus for manufacturing the container 10 and the container so produced. The pulp solution is introduced into a moulding chamber, the water is extracted and an appropriate profile of the container is formed, the profile is transferred to a tooling head and pressure and heat are applied and a peelable polymer liner is applied to the internal face of the container. The addition of the polymer liner ensures that the container is capable of accepting a variety of ambient, chilled, fresh and frozen foodstuffs. After use, the bagasse tray is 100% compostable, and the polymer liner can be removed by a fibre tear and disposed of separately if desired. The application of the liner is performed using thermoforming, blow moulding or spray application. The tray 10 has detents 16. |
