Abstract The article studies the physical and mechanical properties of experimental polymer materials, which are determined by parameters such as Tensile strength s, tensile model E, relative elongation at break ε, which affect the quality of printing under other equal conditions. Experimental studies on the elongation of biaxially oriented polypropylene and polyethylene polymer films were carried out in accordance with the requirements of GOST 14236-81. The tensile modulus E was determined according to Hooke’s law when observing a rectilinear area in the limit of small deformations on the stretching diagram of polymer films.
