“…According to the results, in most cases, men show slightly higher peel forces than women. This is in accordance with other research [29][30] which mentioned that human strength capability of opening packages depends on age. Rowson and Yoxall [30] also reported that typically, women chose a grip that maximized their opportunity of opening the closure and that this grip choice was more limited than that available for men.…”

ABSTRACT:The seal strength of flexible packaging indicates both functional performance and the ease of opening. This research aims to compare the seal peeling mechanisms evaluated by human participants and standard machine tests. The tests were conducted on flexible films used for typical packaging applications, LDPE, LLDPE and Nylon/LLDPE. Human peeling was simulated through the use of novel force measurement equipment. The results showed that the maximum machine peel force set by standard test methods was generally lower than the human peel force for most sealing temperatures. In all film types no significant difference was shown between genders although for people over 65 years peel force was generally lower than for the younger cohort. The results also indicated that peeling speed of human participants was normally higher than the peeling speed set according to the machine test standard.

“…Lid height was not significant when Crawford et al (2002) compared square to round lids. Height was also not included in the list of six key factors presented by Rowson and Yoxall (2011). However, in the current study, a main effect from height was the single most consistent effect and made the greatest difference in both dependent measures and for both participant groups.…”

“…That posture can affect the peak and duration of a force generated by a user and hence associated comfort is well understood by ergonomists studying work related posture [24,25]. Work by Rowson and Yoxall [21] showed that female users consistently used their strongest grip to twist a jar closure and hence it is likely that users will choose muscle postures that optimize their opportunity to produce the maximum force. What is apparent from the literature related to packaging is that measuring these postures and relating them to users ability has to date been limited.…”

“…4 by Langley et al, the researchers tested the maximum torque produced by 34 participants on three different diameters of closure (55 mm, 75 mm and 110 mm) using seven different grip types to assess which of those grip types produce the highest torque [21]. The authors measured hand size but no other anthropometric data such as body mass or height and no data is given on the ages of the participants.…”

Vacuum Lug Closures (VLCs) are a simple, reliable and low cost packaging option used for the protection and promotion of jams, pickles and sauces. Several surveys and anecdotal evidence suggest that packaging of this type can be notoriously difficult to open. Given the difficulty which packaging of this type may pose there has been significant academic research in understanding the difficulties associated with accessing packaging of this type. In response to the qualitative data gathered in these surveys research teams have attempted to quantify the forces that users can apply. What emerges from the approaches taken is a complex picture. Researchers do make comparisons with previous work but numbers of people tested, materials used, diameter and posture differ between research groups as does the information and style of the dissemination of results.Future packaging research experimental design should be more thorough and consistent in the sampling and presentation of data to facilitate repeatability and validity and enable the data gathered to form a larger data set. Further, to create usable 'design limits' for manufacturers and designers to reduce the variability within the data set, more focused measurements should be taken on distinct user groups such as a specific female decile and subgroup, i.e. small handed women between 70 and 80. Working with distinct populations would enable the likelihood of design changes to packaging to be readily compared and assessed.
