Abstract: Natural fibers are nowadays increasingly reinforced as polymer matrix composites, biocomposites since they are presently preferred over artificial fibers. In this research, the composites of eco-packaging made by the compressed lignocellulosic materials of dried hyacinth, dried ground rice husk, and fragmented dried coconut husk fibers were tested for their temperature insulation. They were mixed at various ratios (25:25:50, 33.3:33.3:33.3, and 70:20:10) and thus glued as fiberboards before constructed as the insulator box. The results indicated that the composite mixtures after compression could increase more surface stiffness and heat conductivity. The fiberboard made at the ratio 70:10: 20 showed the best insulator of temperature preservation. The microscopic views as well as the flexural strength and stiffness in the sample at the ratio of 25:25:50 exhibited a good distribution of the fibers in the matrix as well as stronger fiber matrix. The observation of higher water hyacinth contents in the composites provided good interfacial adhesion of the samples and the compression process of less fiber agglomeration and fewer microvoids. However, an increase in the hardness of insulator of coconut husk in the board resulted in more fragility. When considering all fiberboards' mechanical biodegradability, recyclability, cost-effectiveness, higher specific stiffness properties, lightweight, nontoxic properties of these biomaterials, they could be good alternative green materials replacing foam or plastics for being thermo-stabilized insulator. Due to the results of their simple and easily degraded products, easy water absorption and fungal decomposition, as well as its high brittleness and flexibility, further improved properties for particular use in temperature preservation can be compromised for less capacity in temperature maintenance comparing to foam materials. Therefore, the economic fiberboards should be eco-packaging materials and reasonable for the most common customer who concerns on environments.
