“…Plastic materials have important properties which include low weight, high durability, corrosion resistance, and external coating. Plastic is easily treatable and it is the reason for the high production of plastic products (Hazlinger et al, 2010;Ovsik et al, 2019;Habrman et al, 2019;Vašina et al, 2018).…”

This work deals with the study of polymers, and, in particular, polyethylene; its production, types, properties, and usage. The experimental part evaluates the changes of properties of the polyethylene film to be reused under various exposure conditions and selection of the most suitable medium for its application. The film made of low-density polyethylene (LD-PE) was influenced by aggressive media with different pH, specifically Savo for the disinfection, Savo as a Saponate for dish washing and Coca-Cola. On LD-PE films the water absorption and melting temperature evaluation tests were performed. Carried out tests show that the most aggressive medium for LD-PE film from used media is Coca-Cola. The most effective application of LD-PE film like wrapping on container transported is the Savo used as a Saponate for dish washing.

In the article, the study of polymer properties is dealt with as a result of production technology on patterns, which were made by injecting, machining of the extruded profile and 3D printing. All samples were made from iglidur® J260 material, and they were subsequently tested in order to find out properties of roughness, breaking strength, hardness according to Shore, friction coefficient and swelling. Furthermore, the samples were exposed to light microscopy, where material structure was studied, especially from the view of structure defects, distribution and shape of solid lubricants. Based on the performed experiment, it can be stated that production technology affects some properties of the sliding bushing. Above all, properties of the sliding bushing were affected by 3D printing technology. The measured samples had the worst results with regard to roughness and swelling values. Conversely, the values acquired by measuring hardness were surprising as the 3D priting samples reached better results than the samples made by machining. The samples created by injection had the best results compared to others in all tests. The measured values corresponded to the values listed by the manufacturer. Machined sample of the extruded profile is mainly affected by the type of machining, but with consideration to the structure, it can be claimed that the extruded material has the same structure as an injected piece and its properties, with the exception of surface roughness, are on the same level.
