Polyethylene/waste tire dust (WTD) composites were obtained by an in situ polymerization technique. The surface of the WTD was modified with deposition of polyethylene by using plasma polymerization. Ethylene polymerization was carried out using bis(cyclopentadienyl) titanium dichloride (Cp2TiCl2) as homogeneous metallocene catalyst, while diethylaluminum chloride (DEAC), ethylaluminum sesquichloride (EASC) and methyl aluminoxane (MAO) were used as co-catalysts at two different [Al]/[Ti] molar ratio. The main characteristics of the obtained polyethylenes were determined by size exclusion chromatography, thermogravimetric analysis, differential scanning calorimetry and wide-angle X-ray diffraction. The results showed that by using EASC and MAO the highest catalytic activities were presented at a [Al]/[Ti] molar ratio of 9.17 and 18.33 respectively. Even though it was possible to obtain polyethylene using WTD (modified or unmodified) the catalytic activity was lower than in the case in which no WTD was added in ethylene polymerization. Scanning transmission electronic microscopy images evidenced that the original morphology of the polyethylenes was not modified by the presence of WTD.

“…HDPE represents a powerful barrier against moisture, useful to the food packaging industry; however, this material is a poor barrier against oxygen. Therefore, combining it with another material, such as polypropylene, its gas/steam resistance can be improved (Dadfar et al 2009). The deterioration by dehydration in the food product is a quality variable that must be considered in dry environments.…”

The shelf life of third generation snacks (pellets) was estimated through the measurement of physicochemical parameters. Samples were provided by a snack manufacturing industry and were placed in three different types of packaging: high density polyethylene (HDPE); polypropylene/kraft paper; and polypropylene/ HDPE. The samples were tested under different conditions of temperature and relative humidity. Water activity (a w ) at 25 and 408C and moisture gain (89% relative humidity, 258C) were analyzed for 60 days. The polypropylene 1 HDPE packaging showed the best properties for sample preservation, allowing for a shelf life of 1 month under extreme conditions of humidity. Therefore, it is possible to extend the shelf life of the pellets studied by using proper packaging materials to limit phenomena of water sorption.
