Abstract:

Background & Aim: A biaxially oriented polypropylene film (BOPP) is recognized as an appropriate barrier film for most dry foods after lamination with metalized film whether OPP or PET, moreover that film is considered as excellent for moisture and moderate for oxygen permeability. But the question is, will the number still remain the same or change up or down after printing and lamination process. So, the aim of this research is to evaluate the main factors especially like printing remedies �??coating and lamination�?� which affect the strength of barrier properties of the plastic film against gasses and water vapor. Materials & Methods: Six packaged samples were printed with transparent polypropylene films 20 microns with metalized polypropylene for one kind of Egyptian snacks food product before packing. And 3 samples with the same product, but after packing process with different concentration of oxygen. Regarding the gas and moisture permeability tests, all samples were analyzed by OTR permeation analyzer (Oxygen transmission rate) and WVTR permeation analyzer (Water Vapour transmission rate). Results & Conclusions: The impact of printing materials in each of OTR and WVTR results have a positive impact where the permeability has decreased, therefore, increased the ability of plastic film to prevent the gasses and moisture exchang throug the package. Oxygen concentration experiments have showed that there was an influence of oxygen with this characteristic. Fatty free acid and peroxide value present inside the product with a slight change, but totally there was a change in the chemical properties of the product.
