“…Bio-based polymers including polysaccharides and proteins have the ability to form crystalline fi lms with low permeability to oxygen, thus making them interesting for use in packaging applications. Biode-gradable fi lms for use in food packages based on starch, 16,69,70 chitosan, [71][72][73][74] wheat gluten, 75 whey proteins 76 or zein 77 are described in detail in the literature. Bio-based materials have also been used in composite formulations, e.g.…”

“…38,56 Materials that cannot be applied as water dispersions directly, due to insolubility in water, may still be useful in sophisticated composite formulations when dispersed in water-soluble polymer matrices. Examples are PCL-starch 139 composite fi lms and PCLchitosan 76 fi lms. Commercial barrier dispersions are supplied with solids content typically around 50% by weight.…”

New ways to enhance the functionality of paperboard by surface treatment – a review

2008

View full text Add to dashboard Cite

This review summarizes recent development of functional materials to improve the barrier properties of paperboard with emphasis on bio-based polymers. Focus is directed to novel application techniques and water-borne, renewable coating materials. Some aspects on substrate properties and the requirements on food packaging are discussed as are the processability, convertability, recyclability and biodegradability of packaging materials. The functionality, advantages and disadvantages of several bio-based polymers are presented in detail. Among these are starch and cellulose derivatives, chitosan, alginate, wheat gluten, whey proteins, polycaprolactone, poly(lactic acid) and polyhydroxyalkanoates. Also discussed is the enhancement of barrier properties by incorporation of nanosized materials, by application of thin protective top coatings and local reinforcement by self-healing agents.

“…Consequently, there is significant interest in finding new applications for it. 8 According to the aforementioned division of biodegradable polymers, poly(vinyl alcohol) (PVA) belongs to the group of synthetic biodegradable polymers. It is a water-soluble material employed in many practical applications, including the binding of pigments, dip coating, and the production of detergents, adhesives, paints, and solution-cast films.…”

Environmentally friendly polymeric biocomposites based on whey powder, a waste material of the dairy industry, and fully or partially hydrolyzed poly (vinyl alcohol) were prepared and characterized with optical microscopy, Fourier transform infrared spectroscopy, differential scanning calorimetry, and stress-strain analysis, and their biodegradation was evaluated with the modified Zahn-Wellens method and the spectrophotometric determination of poly(vinyl alcohol). In addition, the ability of the biocomposites to absorb moisture and its consequent influence on the mechanical properties were investigated under different storage conditions. The structural differences of the two types of poly(vinyl alcohol) matrices had a significant effect on all the mentioned characteristics. Possible molecular interactions between the polymer matrix and modifier, due to hydrogen bonding, were also examined. First-order kinetics were applied for the biodegradation data. The two-phase character of the biodegradation was shown. The results indicated that whey powder is suitable for the modification of polymers, and this is important for the production of biodegradable polymer materials and the consequent reduction of the environmental load.
