antioxidant active packaging is one of the active packaging that prevents of lipid oxidation by releasing antioxidant during storage of food. in recent years the use of natural antioxidant instead of the synthetic variety in these packaging has been considered. the aim of this study was evaluating the performance of polymeric film coated with natural antioxidant (rosemary extract) to prevent li...

The types of packages and containers in circulation are extremely wide-ranging: glass bottles, aluminum cans, detergent containers, gift-wraps, food packaging films and so forth. According to the statistics for 2007, total expenditure on packages and containers reached 6.2 trillion yen 1). The theme of this article, extrusion lamination processing, plays an important role in manufacturing paper...

In this study, two strains of Aspergillus sp. and Lysinibacillus sp. with remarkable abilities to degrade low-density polyethylene (LDPE) were isolated from landfill soils in Tehran using enrichment culture and screening procedures. The biodegradation process was performed for 126 days in soil using UV- and non-UV-irradiated pure LDPE films without pro-oxidant additives in the presence and abse...

this article reports a study of the thermo-oxidation and biodegradation in the soil of low-density polyethylene/starch films (ldpe/starch) by infrared spectroscopy: films of ldpe/starch blends of different composition (starch content range from 0 to 15% w/w),were prepared and exposed to thermo-oxidation at different temperatures at 80, 90 and 100°c,and buried in the soil of public dump during 3...

In this research, high oxygen-barrier films were organized based on low-density polyethylene (LDPE)/ ethylene vinyl alcohol (EVOH)/ polyethylene-grafted maleic anhydride (LDPE-g-MA) compatibilizer. The effects of 10–30 wt. % EVOH and 0–10 wt. % LDPE-g-MA loadings on the properties of final films were evaluated. The morphology of specimens was observed by using scanning electron microscopy (SEM)...
