There is an awful lot of pointless packaging around. By which I mean what I call the "stylised leaves" kind of pack design. The kind that looks blandly "nice", like stuff you've seen a lot of times before. It doesn't offend. But nor does it catch your eye. It's well behaved. The client and the designer probably went through long agonised discussions over it, to create something broadly similar to lots of other packaging. It doesn't say anything much.
There are some pointless products out there in pointless packaging.
The only test of whether your packaging design works in store is sales. It's not what the design agency tells you. It's not what you think as the founder; you're probably too close to your product to judge how it comes across to outsiders to your brand.
Stage One: Does it catch the consumer's eye?
Look at the amount of choice she has here.
With food inflation, cutting costs on your food bill is attractive. Innocent customers told me recently that they love buying veg pots on promotion.
Innocent announce on their website which supermarket has their products on offer week by week :http://www.innocentdrinks.co.uk/value/
Very helpful to consumers.
