| The article presents the results of experimental studies on selected, mechanical properties of three-layer film, pro- duced by blown film extrusion. Three-layer film was developed for making garbage bags. The research was carried out under industrial conditions. The three-layer film tubes tested were made of low and high density polyethylene and differed in raw material composition, including a different content of recycled polyethylene in individual film layers. Static tensile strength, tear strength and puncture strength tests were carried out using the falling dart meth- od. On the basis of the results obtained, the impact of the content of polyethylene regranulate on the composition of the raw material of the multilayer film in the above-mentioned selected mechanical properties was assessed, in relation to the expected values of these parameters, ensuring the correct use of the three-layer film in the produc- tion process and obtaining a garbage bag with appropriate utility features. A classification system was prepared to develop recipes for dosing waste materials by weight and combining them with the primary LLDPE material, us- ing different proportions of its share in individual layers. Increasing the degree of utilization of waste materials, by increasing their share in the unit product to 55%, allowed maintaining the mechanical parameters of the film, meet- ing the defined industry expectations in terms of static tensile strength and tear strength and puncture resistance. |
