Laser processing of thin films for industrial packaging

Resonant polymer ablation using a compact 3.44 μm fiber laser

“…This study clearly shows that fiber lasers emitting near 3.4 µm have promising prospects for polymer processing applications in various fields. The process can also be applied to a wide variety of polymer compositions, namely PP and PE which are two polymers materials used extensively in the packaging industry, as investigated by Sozzia et al (2014).…”
