Purpose: The main aim of this work is to investigate mechanical properties of plasticized PVC modified by recyclate of polylactide film and influence of aging time in humidity chamber on mechanical properties. Design/methodology/approach: Static test of tensile strength was realized using the testing machine Instron TT-CM 80. Hardness was tested by hardness tester Zwick. Fractures were examined with a scanning electron microscope Zeiss Supra 25. Before the test, the sample was sprayed thin (0.05 mm) silver layer in order to ensure discharge of static electricity from the surface of the sample. PVC granules used is prepared by mixing together at 70°C: PVC 70, plasticizer – dioctyl phthalate FDO Boryszew Erg production and stabilizing lubricant composition. The final materials being studied, obtained by subjecting of the homogenizing extrusion the mixture of granules PVC and recycled PLA. Findings: The analysis of the results gives a real chance to avoid long-term retention of product made from the plastic in the landfill after the end of his exploitation.Research limitations/implications: For the blends of plasticized PVC and recycled PLA derived from films, further structural and tribological resistance examinations are planned. Practical implications: Obtained materials are characterized by satisfactory mechanical properties which make them ideal for use in the packaging industry. The effect of the addition of biodegradable recyclate postconsumer waste in the form of PLA film on plastic susceptibility to degradation under conditions of moisture was confirmed. Originality/value: The article presents selected properties of blends of plasticized PVC and recycled PLA derived from films. The content of recyclate in tested materials varied from 0% to 50%. Introduction to poly (vinyl chloride) degradable additive made it susceptible to degradation in the presence of water, which initiates the biodegradation of polylactide.
