Abstract:This study developed a freshness indicator based on poly(vinyl alcohol) (PVA) and a biohybrid (BH) of Laponite® and anthocyanins adhered to linear low‐density polyethylene (LLDPE) using cold atmospheric plasma (CAP). LLDPE was treated with CAP for 0 to 300 s, which resulted in an increased surface energy, characterized by an important increase in its polar component up to 120 s of treatment, due to the formation of polar groups on the surface of LLDPE. No changes in mechanical properties and water vapor permea… Show more
