Six different composite packaging materials were tested with the trades’ practice of polythene bags in storing smoked catfish for a period of six months. The thickness of the packaging materials ranges from 0.23 to 046 mm with water and oil absorption rates of the packaging materials varies from 0.23 to 10.00 and 0.28 to 10.857 glcm2/mm respectively. The impact resistance weight also varies from 25 to 50 gm. It was observed that the physical properties of the packaging materials are related to the keeping quality of the stored catfish. The two packaging with better engineering properties offered better barrier functionality that gave better keeping quality for the catfish. [O, Foline Folorunsho et al.
