| 20100199884 | Composition for Producing Starch Foam Resistant to Moisture and Freeze-Thaw Cycles - Plastic materials for packaging have increased dramatically in the last two decades, replacing more traditional materials such as paper, glass and metals. Most plastics are made almost entirely from chemicals derived from crude oil that may require hundreds of years to degrade and can kill wildlife if ingested. Disposal of used packaging products has been an ecological problem due to their non-degrability. Agricultural-based materials are beginning to emerge as promising substitutes for petroleum-based plastics. These so-called bio-based materials, such as starch and cellulose, have the advantage of being derived from a renewable source and be biodegradable into a useful compost. | 08-12-2010 |
