    Abstract: We report the transport behaviour of low density polyethylene composites containing both untreated and alkali-treated agro-waste microfibre in three aromatic organic solvents (benzene, toluene, and xylene) at 40, 60 and 80°C by the conventional weight-gain method. The effects of fibre content, alkali treatment, and filler particle size on solvent s... Show More

    Abstract: The effects of local materials as fillers incorporated into the flexible polyether foam recipes were investigated. The fillers; coconut husk and corn cob of mesh sizes of 150 µm respectively were mixed in the ratio of 50:50. Varying percentages of the mixed fillers, 5%, 10%, 15%, 20% and 25% were mixed with polyether foam recipes in the appropriate... Show More

    Abstract: In this study, biodegradable cassava starch/poly (vinyl alcohol) (PVA) trays with and without poly (lactic acid) (PLA) coating were evaluated as possible substitutes for expanded poly (styrene) (EPS) trays in strawberry packaging. The parameters evaluated were physical and chemical parameters of pH, soluble solids and titratable acidity for strawbe... Show More
