For the production of the investigated composites we used biodegradable PLA and PHB polymers and the following bactericidal PHMG derivatives: PHMG granular polyethylene wax, PHMG salt of sulfanilic acid PHMG stearate. The composite films were prepared in the Institute for Engineering of Polymer Materials and Dyes (Poland). They are composed of PLA or PHB polymers and copolymers (PHMG þ organic carriers: polyethylene wax, sulfanilic
acid, and stearate). PHMG derivatives were prepared according to the Patent No: P.388062, 2009
