<p>Azodicarbonamide (ADCA) induces foaming in plastics through thermal decomposition, increasing the porosity. A PE film containing 2 % ADCA was prepared with 0.02 mm thickness and attached to a copper plate inclining 45 degrees. Pores were observed through an optical microscope and analyzed using Image J. The diameter of the pores ranged from 6.73 to 30.43 µm after the laser pulses were applied. The number of pores formed in the PE film was observed to be higher at a fluence value (30 J/cm²) rather than at the peak fluence (78 J/cm²). This indicates that pore formation induced by the chemical blowing agent in the film does not necessarily occur more effectively at higher energy levels and temperature but is optimized at specific fluence ranges. This study highlights the importance of controlled laser parameters for optimizing pore formation in polymer films.</p>
