Utilizing Analytical Hierarical Process to Select The Best Polymeric Material for Food Packaging Applications
This study utilizes an analytic hierarchic process (AHP) to select the best polymeric material for food packaging applications as this will positively affect the quality and shelf life of food products. The proposed model uses seven criteria, including: tensile strength, flexural modulus, water vapor transmission, haze optical properties, melting point, density and cost. Low density polyethylene (LDPE), linear low density polyethylene (LLDPE), high density polyethylene (HDPE), polypropylene (extrusion grade), polypropylene (film grade), expanded polystyrene (EPS) and polyethylene terephthalate (PET) are used as alternatives. The results of this model show that PET is the best material for food packaging among the tested alternatives. Both inconsistency and sensitivity analysis are done and show that model is robust.
