Working principle This technology is based on the antimicrob This technology is based on the antimicrobial activity of some essential oils, and the way to implement this property into [[DSS packaging design|biodegradable packaging materials]]. (1) Materials based on a fibrous (woven or non-woven) substrate are coated with a matrix. The coating matrix is made of one or more biodegradable polymers that allow the controlled emission of one ore more volatile antimicrobial agents (essential oils or molecules extracted from essential oils). The essential oils or their extracts are released depending on the humidity rate of the inside atmosphere of the package. As a consequence, the package is adaptable to a various range of products and conditions: the higher the humidity rate is, the more microorganisms are likely to proliferate (favourable growth condition), but also the more antimicrobial agents are released, limiting the microorganism growth. (2,3,4,6) The principle is conversely applicable for a lower humidity rate. (5) applicable for a lower humidity rate. (5)
