The impact of various packaging attributes on consumer behaviour has thus far been studied in terms of design (Ampuero and Vila, 2006; Favier et al , 2019; Jones et al , 2018; Krishna et al , 2017; Wells et al , 2007; Wang, 2013), imagery (Hota and Charry, 2014; Khan, 2017; Underwood et al , 2001, Van Rompay et al , 2014), size (Wansink, 1996), colour (Mai et al , 2016) and shape (Van Esch et al , 2019; Wansink and Van Ittersum, 2003).…”
