New Technology for Barrier Testing of Flexible Packaging Materials, 1998 Polymers, Laminations & Coatings Conference Proceedings
The permeation of flexible packaging materials has been of importance to packaging engineers, food scientists and material engineers for decades. Recent advances in patented flow technology, mass transfer analysis and understanding, high speed predictive computer analysis and low cell volume construction now give engineers and scientists the ability to determine material and flavor interactions, shelf life estimations, and rapid permeability, solubility and diffusion coefficient analysis. This mass transfer analysis allows material producers, converters and end-users the ability to predict the performance of packaging materials by not only using permeability, but also understanding the importance of solubility and diffusion on this performance. Several specific measurement applications will be discussed.
