Development of eco-packaging using the composites of water hyacinth fibers, rice husk, and coconut fibers for temperature preservation
MetadataShow full item record
The research was to develop environmental packaging from composite materials, hyacinth fiber, rice husk and coconut fiber for temperature preservation to replace the use of foam packaging that cannot be degraded naturally. In the composite materials, water hyacinth fiber, rice husk and coconut fiber at the ratios 7: 1: 2, 1 : 1 : 2 and 1: 1: 1 were extruded by heat using isocyanate glue as a solder and testing the physical and biological properties of composite materials as fiberboard. For testing of temperature preservation of the bio packaging, heat transfer test to obtain the bio-packaging for the environment, the composite materials of fiber, water hyacinth, rice husk and coconut fiber at the ratio of 7 : 1 : 2 was the most appropriate type. Since it had a density of 0.7 grams per cubic centimeter, strength of 26.76 MPa, moisture content of 3.8 percent ages, and swelling of 26.63 percent ages. In dry condition at room temperature, it could store heat for 2 hours and could retain the cold temperature as shown for the temperatures rising from 4 to 30.7 degree Celsius within 2 hours. This research, therefore, presents a new alternative method of natural fiber composite materials application for temperature preservation in order to reduce the use of foam containers and increase cost value to natural bio waste materials.
