Moisture absorption and diffusion characterisation of packaging materials––advanced treatment

摘要: Abstract Unlike thermo-mechanical properties, moisture properties of packaging materials are rarely reported, even though has been known to be at least as damaging temperature plastic packaging. This is in part due the lack characterisation knowledge for such properties. paper tries address this issue through a comprehensive presentation techniques sorption and diffusion Special focuses given advanced treatments on unique characteristics polymeric materials. The effect aspect ratio test specimen accuracy analysed correction factor formulated. Two characterising anisotropic diffusivity presented illustrated with actual experimental data organic laminates. challenges high presented. A new insight into causes physics non-Fickian adsorption along technique alleviate associated challenge.
