Abstract
This paper is about obtaining polyolefin composites with antibacterial properties for the manufacture of hollow blown bodies (vials, bottles, jars) used for the packaging of medical products, cosmetics and food. As main polymer, it was used polypropylene, and as biocide active agent, it was used silver chloride deposited on a support of titanium dioxide or of silica. Antimicrobial silver was added as a premix, using for this purpose the co-polymer ethylene-1-octene. Hollow bodies were obtained by extrusion-blowing and were tested for their mechanical properties and biocompatibility. Keywords: polypropylene, co-(ethylene-1-octene), hollow blown bodies, extrusion
