Purpose: With the development increasing of plastics production the problems associated with their disposal have appeared on. Because of the large volume of plastic wastes and their limited long-term resolution, there is a need for treatment and reuse. For this purpose, with tests of properties, studies on plastics recycling and reprocessing into new products (recyclate) are conducted. The basic technological problem connected with using of secondary material is to clean it. The basic utility problem is the impact of recycling operations on the properties of the secondary material. The work to this issue is mainly devoted. Design/methodology/approach: One of the basic surgery to restore the plastics reusing ability is impurities removing. An available modern way is to use a specialized system of filtration sieves. Optimization problem is to select the proper filter in terms of mechanical properties of the resulting recyclate. In the work, the secondary material with using of grid filter of varying size has been tested. Prepared, with using of purified secondary plastic, three layer film to tensile test was subjected. Findings: The result of the tests described in this work is the preliminary determination of the filtration effect on the mechanical characteristics of the selected secondary materials. Research limitations/implications: The results confirm the impact of the quality of filtration of thermoplastics in the process of secondary processing on the base product properties. The accuracy of the pollution elimination process affects directly on the mechanical characteristics of secondary material. Used in the research procedure filtration system with automatic filter change operation helps to minimize the impact of filtering on the performance of the extrusion process. Practical implications: Practical benefit of the study is the confirmation of the possibility and desirability of material recycling, particularly with using of modern filtration system. Originality/value: The original value of the research are qualitative and quantitative assessment of the effects of filtration on the characteristics of the secondary material.
