The new look will be seen on packs, in advertising and point-of-sale material, and even on RDA Organic vehicles.
It updates the squeezable pouches that were originally created by Yang Rutherford.
The brand is aimed at kids, but with a strong message that the fruit juice is made from organic fruit, and there are no concentrates, no sugar, no colours, preservatives and no "bits".
Patrick O'Flaherty, managing director of RDA Organic, said: "We are thrilled with the work that Identica has undertaken on our kids range they demonstrated great creativity as well as a sound understanding of the kids market and organic sector."
Identica is part of Canadian holding company Cossette that also owns Dare, the digital agency, and ad agency Miles Calcraft Briginshaw Duffy.
Last month former DDB Europe regional director Richard Morris joined as managing director.
