Well known brands such as Heinz, Walkers pay thousands and thousands on their marketing strategies and packaging.
The obstacle they have to overcome is the look of the product. If packaging is poor, and does not stand out, then we will automatically dismiss it. We as consumers, assume visual representation of packaging if poor, will mean that the quality and taste of the product will be rubbish. Therefore, we decide subconsciously not to purchase that product.
Not only do marketing companies rely on visual, they also need to invoke a feel good memory. They want you to associate their brand with something special. Their aim is to keep you loyal to their brand. If they can remind you of a good memory in your past, you will keep buying their brand.
For me, my memory lane journey with a brand is Heinz soup. This reminds me of winter nights when I was young, walking home in the snow and for tea mum would heat up tomato soup. I can still feel the cold, and having that nice hot bowl of soup, how happy and content I felt.
