The overall objective of this research was to explore ageing consumers' attitudes towards currently available food packaging in New Zealand. Ninety-nine individuals (over the age of 60) in New Zealand were surveyed to determine packaging attributes of importance when selecting food products. This was followed with a focus group of 13 individuals to discuss improvements to packaging. Frequencies of responses were calculated for the survey data, and crosstabulations and chi-square tests were used to determine the relationships between variables. Price, safety, size of packaging and ability to recycle were of most importance to these individuals. Problems encountered with food packaging included tight lids, small printing and spillage during opening. Of the types of package closures investigated, opening of packages, rather than resealing of packages proved problematic. Fifty percent or more of respondents indicated that peelable induction seals, lug closures and continuous thread closures were problems that occurred 'very often' or 'frequently'. Sixty-one percent of the participants surveyed had asked for assistance opening some types of packages, and this was particularly prevalent among individuals who had weakness in their arms, hands or wrists. Changes to package closures suggested during the focus groups included increasing the size of twist off caps, larger ring pulls on aluminium cans and including more sliding resealable closures on foil and plastic packaging. Larger printing on labels was also recommended by the participants.

A steady‐state finite element model of moisture transport in corrugated fibreboard is presented and solved using experimentally determined values of moisture permeability in Kraft and recycled paperboard. The model shows reasonable agreement with experimentally measured moisture fluxes. The model also demonstrates that the majority of moisture flux occurs through the air phase. Simplified models based on the sum of resistances in series are shown to be in good agreement with the more complex finite element model and may have some practical utility in the design of packaging for specific applications where the internal moisture environment and/or structural integrity of the packaging is important.
