Firstly, two chitosans (Chi- 244 and Chi-652) were studied according to their ultimate biodegradability. Chi-652 showed the best fi nal biodegradation rate and was then used for subsequent tests in association with papers. Then, oxygen-barrier and aroma-barrier properties of papers, Chi-652 fi lms and Chi-652-coated papers were investigated. The Chi-652 fi lms exhibited oxygen-barrier at low relative humidity and aroma-barrier comparable to synthetic materials already used in the packaged food industry. Both papers exhibited poor barrier properties toward oxygen and aromas. Although chitosan-coated papers showed promising results in regard to the aromabarrier performance of papers, it did not improve their oxygen-barrier properties, probably because of the impact of the coating process on the tri-dimensional structure of the papers.
