Biodegradable polymers have been increasingly used in the last years as packaging materials1. Due to its high biodegradability and low production costs, polylactic acid (PLA) is a highly requested polymer for the preparation of biodegradable polymer products2. In the present work, several blends of PLA with polyadipate ester as plasticizer (Glyplast 206/3NL, GL), cellulose nanofibers (CNF) as reinforcement and an additive for the improvement of elongational viscosity (boistrength 700 provied for , BST) in various proportions have been prepared. Mechanical tensile and melt flow index tests were carried out.
