| 摘要 |
A biodegradable and compostable material that has particular, but not exclusive use as a packaging material, with particular, but not exclusive, application to packing of food products is disclosed. Embodiments of the invention can be biodegradable and made from renewable materials, thereby minimising use of petro-chemicals. Essentially, the invention provides a material that is a combination of a biodegradable polymer and nanoclay. The biodegradable polymer includes one or more of polylactic acid (PLA), a thermoplastic polyhydroxyalkanoate (PHA) or polyhydroxybutyrate (PHB). Embodiments may additionally include a bulking agent, such as sawdust, and a colourant, such as chlorophyll or carbon black. |
