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 exchange through ‎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.
