flexible packaging

An overview of the current state of digital printing in the packaging industry is provided in the article. The key technologies (inkjet and electrophotographic printing), materials, andareasofapplicationof digital printing systems inpackagingmanufacturing are examined. The advantages of digital printing – personalization, high production preparation speed, cost­efficiency for small print runs, and integration with smart technologies – are analyzed.

This study investigates the influence of low­temperature exposure (–18 °C) and ultraviolet (UV) irradiation on the mechanical properties of polymer films used in flexible packaging applications. The research focuses on widely used materials, including glossy and matte polypropylene (PP) and polyethylene terephthalate (PET) films of various thicknesses. Mechanical tensile tests were performed to evaluate the elasticity, tensile strength, and mechanical resistance of the films before and after exposure to cold and UV radiation.
