This article presents research on protective packets of anti-blow vests in use among law enforcement services of the Polish Police. Basic information on the ageing process of polymer plastics are given. Te types of ageing are presented as well as the phenomena causing the process within the plastics. Te approved programme of accelerated ageing tests of the protective packets of anti-blow vests was characterised. Te conditions of the tests were defned as well as the groups of properties to be tested, which are the criteria of the resistance of the test objects to ageing. Te results of the research on the protective properties of anti-blow packets before and afer tests of laboratory ageing are presented. Te results of the research on packets of anti-blow vests afer 10 years of real-time ageing are also presented. A concluding analysis of the research results and impact of ageing processes on the protective properties of the products tested was performed.
