Innovative cellulose-based multilayer packaging films

    Research output: Contribution to conferenceOther conference contributionScientific


    All-cellulosic multilayer packaging films are built from two different types of wood cellulose materials: enzymatically fibrillated cellulose (HefCel) and a cellulose fatty acid ester (MMCC). The HefCel material consists of hardwood cellulose nanofibrils with high surface area and hydrophilicity. The densely packed structure of cellulose nanofibrils in films and coatings enables their outstanding oxygen, carbon dioxide, grease and mineral oil barrier properties. The MMCC material is made from the softwood cellulose functionalized with biomass based hydrophobic fatty acid. Due to the chemical structure, MMCC forms completely transparent, flexible and smooth films and coatings having excellent moisture barrier and heat sealability properties. The moisture barrier properties of MMCC reimburse the moisture sensitivity of the HefCel material. The cellulose technologies presented are patented by VTT (WO2016/193542, FI2017/5114, WO2013/060934, PCT/FI2015/050835, FI2016/5075, WO 2015/092146 A1). These two materials have complementary barrier properties and to reach outstanding packaging performance they have been combined them into one, compostable 3-layer film structure with excellent technical performance.
