The properties of packaging materials have been investigated and have been found to have effects on packaged foods either positively or negatively, hence the need for appropriate packaging materials for food products. This study investigated the barrier properties (permeability values) of food packaging materials as they affect the stability of packaged food products. The focus of this study was on two different packaging materials, namely Low Density Polyethylene (LDPE) and Polyethylene Terephthalate (PET) films and how their barrier properties affect the stability of packaged foods, particularly, the dried grinded pepper selected for this study. The barrier properties of the two selected packaging materials were investigated through direct method of shelf life study. The selected packaging materials of 0.08mm thickness each were developed into pouches of equal sizes and shapes with length 50cm and breadth 30cm each. 50g of the dried grinded pepper (Piripiri ) was packaged with the pouches made with low density polyethylene and polyethylene terephthalate films. Proximate and microbial analyses of the dried grinded pepper were carried out before packaging. Post packaging analyses were also carried out after 180days of storage and results of the analyses were recorded. Parameters such as moisture content, ash content, crude fibre , crude protein and carbohydrate were investigated using AOAC method. Elemental analysis was done using energy dispensive x-ray flourensce ( EDXRF ) method
