3. Effects of plasticizing and crosslinking on coatings based on blends of starch-PVOH and starch-lignin
Abstract : A barrier material is usually needed on a fiber-based food package to protect the packed food from gases and moisture and thus maintain its quality. Barrier materials presently used in food packaging applications are mostly petroleum-based polymers. READ MORE

4. Thermoplastic processing of starch and cellulose-containing polymers
Abstract : Starch and cellulose are two naturally occurring polymers that have the potential to reduce the dependence on fossil resources if used as replacements or as complements to synthetic polymers. There are however some problems associated with the use of these polymers that have to be addressed and solved. READ MORE

5. Effects of plasticizing and crosslinking on the mechanical and barrier properties of coatings based on blends of starch and poly(vinyl alcohol)
Abstract : In the last decades, intensive research has been carried out in order to replace oil-based polymers with bio-based polymers due to growing environmental concerns. So far, most of the barrier materials used in food packaging are petroleum-based materials. READ MORE
