To apply the nanomaterial as a component in the packaging material structure, in this research, the carboxymethyl cellulose (CMC)/polyvinyl alcohol (PVA) film were prepared with three levels of nanoclay particles (0.5, 1 and 3%) using solution casting evaporation method. The incorporation of nanoclay on mechanical, water vapor permeability, and oxygen barrier properties of CMC/PVA-based film wa...

for button mushrooms packaging, the packaging films with high permeability to oxygen and carbon dioxide are required. permeability of plastic films such as pvc lead to loss of weight (and thus economic value) and textural changes are undesirable for button mushroom. so packaging film of polyolefins (pd 941 and pd 961) can be used. also the new film, hydrophilic materials such as films made from...

Blown Film Extrusion is the primary technology used to make plastic films especially for the packaging industry. Its machines produce protective films used in many industries including food and pharmaceuticals – that extend product shelf life and improve consumer appeal. Products such as trash bags, frozen food packaging, shrink wrap, stretch film labeling, form, fill and seal packaging, medica...

Anisotropic conductive films (ACFs) received a great deal of attention in recent years for interconnection applications in electronic packaging. This paper reports the behaviour of ACF joints under various mechanical loading, i.e., die shear and cyclic fatigue in shear. The mechanical behaviour of ACF joints that have been exposed to environmental effects, i.e., high moisture and elevated tempe...

The carboxymethyl cellulose (CMC)/polyvinyl alcohol (PVA) film were prepared by adding three levels of nanoclay particles (0.5, 1 and 3%) using solution casting evaporation method. The incorporation of nanoclay on mechanical, water vapor permeability, and oxygen barrier properties of CMC/PVA-based film was investigated. The best result was obtained through the nanocomposite film contain 3% nano...

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...

apricot is climacteric and its ripening process is regulated by ethylene, therefore, inhibiting ethylene biosynthesis or action should slow the ripening process. this study was conducted to decrease materials losses and increase storage life of fruit by proper packaging. different packaging (polyethylene film, polyethylene film with ethylene absorbent, shrink pack and control) were used. after ...

in the present research, effects of modified atmosphere packaging (map) includingthree gas combinations and two packaging films (low density polyethylene (ldpe) andpolypropylene (pp)) on postharvest quality and storage-life of 'elberta' peach wereevaluated. the study was conducted as a factorial experiment based on crd(completely randomized design) with three replicates for 9 weeks. f...

The present study was carried out to investigate the preparation of chitosan-Ag nanocomposite filmfor food packaging. Since chitosan is a suitable alternative to produce packaging films due to favorablefactors such as biodegradability and abundance in the world, therefore in this study, it was preparedchitosan-Ag nanocomposite with antibacterial properties for food packaging b...

Phthalates are esters of phthalic acid, mainly used as plasticizer in polymeric packaging materials. The main objective of this research was to determine the exact roots of the phthalate esters in the Iranian flexible/laminated packaging films commercially used for food products such as ketchup, spaghetti, mayonnaise, black tea and snack foods. This investigation was carried out by analyzing th...
