Visual Marketing Through Secondary Packaging

Visual Marketing Through Secondary Packaging Sean Gregor, Vancouver, Canada
Packaging for food products has been proven to be influential in capturing consumer attention and influencing purchase decisions, the role of secondary packaging in brand awareness may just be as significant. By Jerry Koefelda, senior director, Rehrig Pacific Company

The result of several years of a sluggish economy is greater pressure on marketers to drive brand growth. With 76 precent of consumers’ purchasing decisions being made in-store and being heavily influenced by point-of-purchase marketing material, product packaging has the opportunity to be one of the greatest influencers in the formation of consumers’ brand preferences.

To lift brand awareness and drive growth at the point-of-purchase, a product must grab the consumer’s visual attention and do so with the consumer’s first impression. This is the first step in driving consumer behaviour through the retail marketing funnel from a first impression through to purchase.

For food products specifically, the packaging’s ability to capture attention has been shown to increase the probability of purchase. Visual attention has a significant positive effect on brand choice and is a vital and often the only way to acquire information about brands in consumer choice contexts.

Numerous studies, including a 2007 study by the Wharton School of Business, have proven a positive and significant relationship between consumer attention and purchase intent. One such study reports that, “in addition to branding, consumer attention also increases purchase intent, in particular first choice of purchase.”

These lay the foundation for the investigation of a hypothesis: a unique secondary package design with on-message, brand building colour and graphics can lift brand awareness and increase purchase intent when integrated into in-store marketing campaigns.

Influence Of Secondary Package Design

Testing of the hypothesis was carried out at Clemson University’s CUshopTM, an immersive shopping environment used to test consumer behaviour.

Participants in the study were equipped with eye-tracking hardware as a means of recording the areas to which their attention was directed during a simple shopping task. In order to gauge attention patterns, the eye-tracking technology capitalises on the fact that attention coordinates eye movement.

The specific types of secondary packaging used in the study were reusable plastic crates for two-litre bottles of carbonated soft drink. Specifically for this purpose, a new proprietary reusable crate was introduced, manufactured with the exact label colours and multi-colour logo of a US beverage company.

This branded reusable crate was evaluated against a standard crate in the industry. The standard reusable crate is manufactured in a non-specific shade of the same colour, blue, and does not feature a logo in offset or company specific colours.

The reusable crates were filled in equal number with regular and diet varieties of a popular carbonated soft drink (CSD). Competing brands of CSD were not included in order to focus the study on package design rather than brand loyalty. All CSD was displayed in reusable crates, again to focus the research and eliminate any factors that may have led to the collection of erroneous data.

The stimulus, the reusable crates and product combined, was delineated into three areas of interest (AOIs), consisting of the products alone, the reusable crates alone and the combined CSD space. Delineating the stimulus in this manner allowed separation of fixation data between the reusable crates and the product.

The AOI are denoted as:

  • Standard Product AOI: The area of the bottles only when in a standard reusable crate
  • Branded Product AOI: The area of the bottles only when in a branded reusable crate
  • Standard Reusable Crate AOI: The area of the standard reusable crates only
  • Branded Reusable Crate AOI: The area of the branded reusable crates only
  • Standard Combined AOI: The area of the bottles and standard reusable crates combined
  • Branded Combined AOI: The area of the bottles and branded reusable crates combined

Tools & Participants

The participants eye movements were tracked using Tobii eye-tracking glasses. The glasses are of an ultra-light design, looking similar to reading glasses. Used in conjunction with a recording unit and infrared (IR) markers, participants’ eye movements can be recorded by following the movement of the right pupil.

Data is recorded at a rate of 30 times per second. The IR markers allow for automated mapping and data aggregation.

A total of 101 participants (49 male, 52 female) took part in the study. During the analysis, 12 participants were removed from consideration for poor calibration or failure to follow the study instructions, leaving 89 participants (44 male, 45 female).

Participants ranged in age from 18 to 79 years with a mean age of 31.2 years. The income range distribution of the participants was diverse, ranging from less than US$24,999 to over US$200,000 annually.

Experimental Design & Procedure

The experiment was designed as a simple shopping task. Participants were given a shopping list with several categories of items, one of which was carbonated soft drinks, and instructed to visit the shop as they would during a normal shopping trip.

However, in this instance, they were asked to write down their selection for each category. They were instructed not to pick up any products but instead to write down the product name.

The study was carried out over three days with the only manipulation being a variation in which reusable crate was present. On the first day, only standard reusable crates were displayed, the branded, or new reusable crates, were displayed on the second day, and on the final day of testing, both reusable crates were displayed side-by-side.

Testing on the third day was performed only to provide a side-by-side comparison. The data was not included in the analysis. Again, this was done to avoid slanting the results.

Participants were given no foresight into what form of packaging the carbonated soft drink would be in or what type of carbonated soft drink would be available. After selecting a product for each item on the shopping list and exiting the shop, participants were asked to complete a survey collecting basic demographic information and several preference questions regarding shopping.

Participants were also asked several open-ended questions attempting to determine the source of their decisions.

Statistical Analysis

The recorded eye movement data was exported from Tobii Studio and statistically analysed.

Analysis of fixation count revealed a significant difference favouring the branded combined AOI (area of the bottles and reusable crates combined) and the branded product AOI (p<0.05), but there was no significant difference between the two reusable crate AOIs (p>0.05).

With respect to fixation duration, there was a significant difference between the standard product AOI and the branded product AOI (p<0.05). The branded product AOI received significantly longer fixation duration. Similarly, there were significant differences favouring the branded combined AOI (p<0.05) and branded reusable crate AOI (p<0.01).

Lastly, for time to first fixation, there was a significant difference (p<0.01) favouring the branded reusable crate AOI, meaning participants looked at the branded reusable crates quicker. However, no significant difference (p>0.05) was found for the combined AOI or product AOI.

The results indicate that the branded secondary packaging (the reusable crate) did significantly impact the shopper’s attention patterns. Most importantly, both the fixation count and fixation duration increased for the branded product AOI and the branded combined AOI.

Evaluation of the fixation count results for the product and combined AOIs indicated significant increases in fixation count for the branded AOIs. Referring to the methodology of the study, the only variable that changed from standard to branded AOIs was the reusable crate.

As it relates to the hypothesis, this indicates that a change from the standard reusable crate to a branded reusable crate did drive an increase in shopper attention on both the combined AOI and, more relevantly, on the product AOI.

Evaluation of the fixation count results for the reusable crate AOIs indicate that although there was a higher fixation count on the branded reusable crate AOI, it was not statistically significant and could essentially be due to random chance.

This may indicate participants looked at the standard and branded reusable crates about as often, but while looking at them, spent longer looking at the branded reusable crate.

Similarly, analysis of the fixation duration results indicates that a change to branded reusable crates did drive an increase in shopper’s attention in all three categories of AOI. This demonstrates an increase in the shopper’s cognitive processing of the information presented in the branded displays.

Time to first fixation (TTFF) results for the reusable crate AOIs do indicate a significantly shorter period for participants to fixate on the branded reusable crate AOI. However, TTFF results for the product and combined AOIs indicate participants found the AOIs in approximately the same amount of time.

The numerical differences in these categories were most likely due to random chance or insufficient statistical power. Given the extremely small variations (a difference of 30 ms in the time to first fixation), this is not terribly surprising, such a limited time frame is unlikely to be sufficient for cognitive processing to occur.

Given that TTFF is generally an auxiliary metric and not one considered to be as significant an indicator of cognitive attention as fixation duration, this metric does not provide significant data for or against the hypothesis.

Study Results

A portion of the significant results of this experiment can be summarised in some revealing bullet points:

  • The product in the branded reusable crates received 54 percent more fixations
  • The product in the branded reusable crates was looked at for 46 percent more time
  • The product in the branded reusable crate was looked at 10 percent quicker
  • The combined area of the product and the branded reusable crate received 47 percent more fixations
  • The combined area of the product and the branded reusable crate was looked at for 34 percent more time
  • The combination of the product and reusable crate was looked at 10 percent quicker
  • The branded reusable crates were looked at for 13 percent more time
  • The branded reusable crate received 32 percent more fixations
  • The branded reusable crate was looked at 93 percent quicker

As stated above, eye movement data from this study illustrates significant increases in shopper attention on the product being displayed. Viewing these results in conjunction with the results of corroborating studies as referenced above does indicate substantial increases in consumer’s cognitive processing of the product in the display and, therefore, increase in their intention to purchase the product.

Therefore, it can be concluded that statistical evidence from this study does support the hypothesis and prove that unique secondary package design with on-message, brand building colour and graphics can lift brand awareness and increase purchase intent.
