The objective of this work was to study the characterization of the resin from the post-industrial recycling of the stand-up pouch packaging (a bag that stands upright"), with the goal of providing information that helps and encourages the mechanical recycling of multilayers flexible plastic packaging. We studied the structure of the stand-up pouch packaging with the following composition: 11.2% of Poly (ethylene terephthalate) (PET); 11.6% Polyamide (PA); 69.5% of polyethylene (PE); and 7.7% of paints and adhesives, used for cosmetics packaging. The obtained blend by mechanical recycling of the material was characterized, through mechanical tests of resistance to bending at three point, (ASTM D 790), Izod impact strength (ASTM D 256), tensile strength (AST M D 638) and shore D hardness (ASTM D 2240). Thermal tests as under load deflection temperature (ASTM D 648) and Vicat softening temperature (ASTM D 1525). rheological measurements, melt index (ASTM D 1238), dynamic-mechanical analysis (DMA), analysis of chemical properties through the images of the samples fracture surface made with SEM (scanning electron microscope), and energy dispersive analysis (EDS. The results obtained in the tests described above were compared to the values found in analyzes made with the materials separately, and it was found that the blend from the recycling package stand-up pouch is immiscible, that the presence of PET and PA helps to increase the mechanical properties of the material relative to the polyethylene (PE) but do not influence the thermal properties, which were analyzed by means of tests of deflection temperature under load (HDT) and Vicat softening temperature (VICAT).
