Method For Routine Density Measurement Of Sublimating Solid Carbon Dioxide (Dry Ice) For Cold-Chain Quality Control, Kimberly Hafner, Bruce A. Welt, William Pelletier
Method For Routine Density Measurement Of Sublimating Solid Carbon Dioxide (Dry Ice) For Cold-Chain Quality Control, Kimberly Hafner, Bruce A. Welt, William Pelletier
Journal of Applied Packaging Research
With recent development of vaccines and biologics, interest in dry ice for cold chain shipping has increased. However, understanding of how dry ice properties relate to performance is not well understood. This study introduces a simple method for measuring a key property of dry ice that has been shown to correlate to performance. The method involves a variant of the water displacement method for determining volume, where dense solid particles are used in place of water for volume determination. Three particle types (sieved sand, glass beads, and stainless-steel shot) were tested for suitability with the particle displacement method. Items of …

Evaluation Boundary And Design Method For Insulating Packages, Liao Pan, Jun Wang, Lixin Lu
Journal of Applied Packaging Research
To evaluate the failure potential of insulated packaging to heat outside, a so-called evaluation boundary for insulating packages was proposed for designing and estimating insulating packages based on the heat transfer law between the environment and a packaged product through packaging. Three evaluation parameters were suggested for describing the failure mechanism of insulating packages. The validity of the presented evaluation boundary was verified by the experimental data. Finally, a new design method of insulating packages based on the boundary was proposed and an application example was performed as a demonstration. The results indicated that the three evaluation parameters (which are …
