Squeeze tubes reduce product consumption compared to traditional packaging, supporting the consumption monitoring hypothesis. This effect is stronger for individuals who tend to overeat, highlighting packaging
Area of Science:
- Consumer Behavior
- Food Science
- Packaging Engineering
Background:
- Squeeze tubes are a growing packaging format.
- Their impact on serving sizes is not well understood.
- Existing research contrasts motor fluency and consumption monitoring hypotheses.
Purpose of the Study:
- To investigate if squeeze tubes influence consumer serving sizes.
- To differentiate between the motor fluency and consumption monitoring hypotheses.
- To explore the role of eating restraint in this effect.
Main Methods:
- Three studies were conducted comparing squeeze tubes to traditional packaging.
- Consumer product usage was measured.
- Eating restraint was assessed.
Main Results:
- Consumers used less product from squeeze tubes than traditional containers.
- This reduction supports the consumption monitoring hypothesis.
- The effect was more pronounced in unrestrained eaters.
Conclusions:
- Squeeze tube packaging can lead to reduced consumption.
- Ease of monitoring consumption drives this effect.
- Findings are relevant for consumers, policymakers, and manufacturers.
