Thermal, mechanical and permeation properties of gamma-irradiated multilayer food packaging films containing a buried layer of recycled low-density polyethylene

Influence of oxygen and long term storage on the profile of volatile compounds released from polymeric multilayer food contact materials sterilized by gamma irradiation

“…Airtightness of bags was also demonstrated, since no significant differences were observed between the gas volume of both initial and stored bags. These results are consistent with the studies reporting that gamma irradiation does not cause significant changes in oxygen and water vapor permeability [31,32]. Consequently, the generalized and non-discriminatory decrease of concentration along the time cannot be justified by losses due to the permeability or by a dilution effect.…”

Effect of electron-beam and gamma-irradiation on physicochemical and mechanical properties of polypropylene syringes as a function of irradiation dose: Study under vacuum

“…The recorded DSC curves for the control and irradiated samples show only one melting peak. This provides evidence that the polymer studied is characterized by one crystalline form (Yagoubi et al, 1999;Chytiri et al, 2006).…”

Multifunctional hydrolyzed EVA membranes with tunable microstructure and water barrier properties

“…DSC has been widely used to evaluate the thermal property of the single component polymers and to characterize the polymer composites [46][47][48] and multilayered structures [10,49,50]. So, DSC measurements were carried out in order to evaluate the structural modifications occurring during the EVA hydrolysis.…”
