1. Hemicellulose as barrier material
Abstract : Polysaccharides constitute an important source of raw materials for the packaging industry today. Polysaccharides have good natural barrier properties which are necessary for packaging films. Cellulose is the forerunner among renewable polymers for such applications. Hemicelluloses represent a new interesting breed of barrier materials. READ MORE

2. Barrier Properties of greaseproof paper
Abstract : The barrier properties of greaseproof paper are achieved by extensive beating of the fibres. This treatment results in high costs for energy, both as beating energy and drying energy. A full-scale trial has been performed to investigate the role of the pulp with respect to energy demand and the barrier properties of the final papers. READ MORE

3. Intrarenal oxygen homeostasis in acute and chronic kidney disease
Abstract : Renal hypoxia has been recognized as a common feature of acute and chronic kidney injury arising from varying etiologies. It has also been proposed to provide a driving mechanism for the transition from acute to chronic kidney disease (CKD). READ MORE

4. Xyloglucan-based polymers and nanocomposites – modification, properties and barrier film applications
Abstract : Biopolymers from renewable resources are of interest for packaging applications as an alternative to conventional petroleum-based polymers. One of the major application areas for biopolymers is food packaging, where a candidate polymer should meet critical requirements such as mechanical and oxygen barrier performance, also in humid conditions.

5. Influence of paper properties and polymer coatings on barrier properties of greaseproof paper
Abstract : Greaseproof paper has a dense structure and therefore provides a natural barrier against materials like fat and oils. The barrier is obtained by extensive refining of the pulp. READ MORE
