    Abstract : The aim of this diploma work was to execute surface treatment of non-ionic cellulose ethers EHEC that AkzoNobel provides under the tradename Bermocoll®. In order for the cellulose ether to dissolve without forming lumps, some surface treatment is commonly required. READ MORE

  5. 9. Chemical Modification of NFC: Development of Renewable Barriers for Packaging Applications

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Jesper Pettersson; [2012]
    Keywords : Packaging; nanofibrillated cellulose NFC ; polymer modification; grafting; biocomposite;

    Abstract : Globalization and centralization have resulted in prolonged transportation time between producer and consumer, and thus put more demand on the perseveration of a product for longer duration and protect it from oxidation. The presence of oxygen in packages severely foreshortens the storage life as it yield losses of nutrients and allow microbial growth, which can cause changes in smell, taste as well as discoloration.
