Mars has revamped the packaging of Refuel to play up its milk content.

One-litre cartons, 330ml bottles and the 400ml sports-cap format will feature a milk splash on a ­simple dark background to draw attention to the "milk goodness of the drink", which Mars said has the optimum ratio of carbohydrate to protein.

Meanwhile, Coca-Cola Enterprises has unveiled new packaging for its Oasis range and announced the return of a blackcurrant & apple variant. Available from 15 April, the relaunched drink will be supported with a multimedia advertising campaign.
