Atypical food packaging draws attention in the retail environment, and therefore increases product salience.
However, until now, no research has focused on how atypical packaging affects the persuasive
impact of other food information. In the present study, we propose that atypical packaging enhances processing
of product information, affecting product claim recall and product evaluation in turn. Specifically,
we argue that atypical packaging may have detrimental consequences for the evaluation of food products
that are presented with so-called weak product claims. Participants (N = 102) were presented with an
online shopping environment, showing a food product with either a typical or an atypical package,
and product claims that were either weak or strong. Results showed that atypical shaped packaging
design enhanced cognitive processing, which in turn decreased the persuasive impact of weak claims
on willingness to pay, and increased the persuasive impact of strong product claims on quality judgment.
Furthermore, product knowledge improved when packaging design was atypical, through increased
processing.
