Plastics, due to their low cost, good mechanical properties and easy-high temperature processability, are widely used to prepare biomedical devices and food packaging. However, typically they do not have inherent antibacterial properties, an important feature in prevention of infection in humans by microorganisms like bacteria, molds, yeasts. Therefore, many efforts have been made in the last decades using novel nanotechnology and nanoscience knowledge in order to obtain nanomaterials with determined functionality. Among the wide range of antimicrobial plastics, metal-polymer nanocomposite and particularly silver-polymer are the subject of increased interest. Following our previous research on this topic, here we report some novel composite plastics, using polyethylene as polymer matrix, containing Silver(I) Acylpyrazolonate additives. They have undergone on specific tests such as antimicrobial activity against suspensions of E. coli, P. aeruginosa and S. aureus, test by contact, release test in according to EU Legislation and Acute Toxicity test using D.

Abstract
Plastics, due to their low cost, good mechanical properties and easy-high temperature processability, are widely used to prepare biomedical devices and food packaging. However, typically they do not have inherent antibacterial properties, an important feature in prevention of infection in humans by microorganisms like bacteria, molds, yeasts. Therefore, many efforts have been made in the last decades using novel nanotechnology and nanoscience knowledge in order to obtain nanomaterials with determined functionality. Among the wide range of antimicrobial plastics, metal-polymer nanocomposite and particularly silver-polymer are the subject of increased interest. Following our previous research on this topic, here we report some novel composite plastics, using polyethylene as polymer matrix, containing Silver(I) Acylpyrazolonate additives. They have undergone on specific tests such as antimicrobial activity against suspensions of E. coli, P. aeruginosa and S. aureus, test by contact, release test in according to EU Legislation and Acute Toxicity test using D.
