The logo, which has been made larger and bolder to make the brand stand out more on the shelf, will be used across 7Up cans and bottles from February.
The new packaging focuses on the ingredients list in an attempt to make the range more appealing to consumers.
The redesign covers the whole brand range including 7Up Regular, 7Up Free and 7Up Cherry.
Lucy Harman, brand manager, 7Up, Britvic, said: "We're taking a modern approach to redesigning the original lemon-lime soft drink and making the packaging reflect the new 'simpler is better' proposition.
"The new packaging looks fantastic on shelf and we're confident it will stand out to consumers who enjoy lemon-lime drinks, as well as appealing to 7Up's target market of young adults."
The soft drink is owned by PepsiCo UK and manufactured by Britvic.
