TRASOLOGICAL STUDY OF TRACES OF HEAT TREATMENT ON POLYETHYLENE PRODUCTS AND IDENTIFICATION OF DEVICES, WHAT LEFT THOSE TRACES AS A NEW KIND OF FORENSIC TRASOLOGICAL EXAMINATION

Abstract

The purpose of the article is to substantiate the expediency of initiating a trasological study of traces of heat treatment on polyethylene products and to identify the devices that left them as a new type of forensic trasological examination. Methodology. The reliability of the obtained results and conclusions is ensured by the use of general (general scientific) and special methods of cognition. The object and subject of research are chosen by the dialectical method, its purpose and tasks are substantiated; by the method of analysis and generalization the necessary substantiations on the basis of the theory of welding of polymeric films are carried out; the mechanism of formation of seams on film materials is studied by a structural-functional method; experimental methods made experimental samples of traces of heat treatment, using the method of microscopic examination studied traces of heat treatment on objects of research and experimental samples and their structure, the results of which established convergent individual (identification) features in the traces. Scientific novelty. A new type of trasological research has been theoretically substantiated, methodologically developed and experimentally tested in specific expert proceedings. Conclusions. Argued on
the basis of a study of modern features of criminal offenses in the field of drugs and psychotropic substances in terms of their masking and transportation, analysis of the main provisions of the theory of welding film materials made of plastics and the mechanism of seams on them, as well as today's realities of trasological expertise. It is proved as a result of research of samples of traces of heat treatment on packing materials of concrete criminal proceedings and
the device provided for research that introduction in expert practice of a new kind of trasological researches will expand possibilities of detection of crimes in part of identification of devices which have left traces of heat treatment. branches of criminology – trasology. The experience of conducting trasological examination in the study of traces of heat treatment on polyethylene products, determining their origin and identifying specific devices that left these traces, as well as suggestions that can form the basis of appropriate guidelines for forensic experts and law enforcement agencies.
