Abstract

Calculation of gas permeation in food packaging structures can be done using a steady‐state analysis employing the permeability coefficient. While this approach is adequate for some applications, for many others a time‐dependent transport analysis must be considered to make quantitative predictions of shelf life. The limitation of the simple permeability analysis for multilayer structures is illustrated for Saran‐coated polycarbonate and poly(ethylene terephthalate) soda cans. These more detailed calculations on package structures can be done using standard computer library routines to include both the effect of gas sorption and diffusion.
