Effect of Gamma Irradiation on Physico-Mechanical Properties of Spice Packaging FilmsMizani, M; Sheikh, N; Ebrahimi, S.N; Gerami, A; Tavakoli, A.F; 2009; Effect of Gamma Irradiation on Physico-Mechanical Properties of Spice Packaging Films; Elsevier, Vol. 78, No. 78, 806-809.
Abstract: Physico-mechanical properties of two types of laminated films, commercially used for spice packaging, are investigated after gamma irradiation at 8, 10 and 15 kGy. Data showed that polyethylene terephthalate/polyethylene terephthalate/linear low density polyethylene (PET/PET/LLDPE) was more resistant to radiation compared to biaxially oriented polypropylene/cast polypropylene (BOPP/CPP) and its barrier properties slightly improved up to 15 kGy. Oxygen transmission rate of BOPP/CPP was increased by 25%, and the melting peak temperature was decreased by 3.9% at 15kGy, which may lead to oxidation of packaged spices and loss of their aroma/flavour, respectively.
