Abstract:

  

 

  

Purposes of employing barrier    coatings in packaging, and in particular food packaging, can be to increase    the shelf life, preserve colour, odour, and taste, and to protect from a    harmful environment in general. Barrier coatings can thus help to reduce food    waste along the value chain until end use. Including both materials choice    for packaging and the possible fates of the used package, even further steps    to provide greater knowledge for decisions on choices of packaging solutions.    To that end, we have conducted several experimental and transport modeling    studies on oxygen barrier coatings performance. The coating system of choice    has been dispersion coatings of poly vinyl alcohol (PVOH), with additions of    kaolin. Physical and chemical features of the coatings were characterized to    obtain information on polymer crystallinity, free volume and filler    orientation as these characteristics are influential to the oxygen mass    transport performance. In turn, the oxygen mass transport was also measured,    both in steady state and dynamically. In so doing, we obtained information    useful for developing a general model to describe the oxygen permeability    taking into account the physical and chemical features, described above, of    the coating layer.[1] Attempts on describing the interdependence and impact,    for instance between crystalline and amorphous polymer regions and moisture,    was added to the model.[2] The model showed agreement to experimental data    for PVOH-kaolin coating in this particular case. However, the basic permeability    model has been applied to  many    different polymers.[3]

  

To further explore the    potential of these types of coating, which are technically possible to    produce in paperboard production, an economic-environmental impact    comparison to other existing material solutions was made.[4] Four barrier    material alternatives – starch, polyethylene, ethyl vinyl alcohol (chosen as    an alternative for PVOH, where data was difficult to obtain) and kaolin, and    latex and kaolin, were analyzed with respect to cost and global warming    potential. Weighting and comparing cost to environmental aspect, weighting    factors based on interviews with experts in the packaging value chain,    starch emerges as the most sustainable alternative. However, previous    coating and mass transport studies also shows how these renewable materials    require some further technical development to be competitive.

  

The mass transport model can    serve as a tool for customizing barrier coatings and to predict the barrier    performance, as permeability is obtained and thus shelf-life estimation is    possible. The overall concept, the combination of assessment of structural    performance and the environmental studies, can be employed to find    sustainable food packaging solutions.
