The agency stated that the new design puts a contemporary feel to a brand that has been in the health-food market for decades.
The fruit of each drink has been emphasised at the forefront of the label, along with copy to highlight its healthiness, which states: "no added sugar" and "eight calories per serving".
Michael Beard, spokesman for Healthy Food Brands, which owns the drinks, said: "Research told us that consumers would like to be able to drink a low-calorie lime juice cordial that has the same high fruit content as the existing Lemon PLJ.
"P&W's designs bring PLJ right up to date and will give the brand more standout on shelf."
