A drinks pouch that needs a straw punched through foil at an angle sounds like an odd design choice — until you realise what problem it was actually built to solve.
A 1969 packaging problem
Capri-Sun was created in 1969 by Rudolf Wild GmbH, a German company based in Eppelheim, and launched domestically as Capri-Sonne before the Capri-Sun name took over in export markets. At the time, children's drinks were sold mainly in glass bottles or cartons, both heavier and more breakable than something meant to go in a school bag every day.
Why the foil pouch works
The pouch is made from a laminated foil material, not plain plastic, which blocks out light and oxygen far more effectively than a clear bottle. That barrier is what lets the drink stay fresh without relying on higher levels of preservatives, and the pouch itself is both lightweight and effectively unbreakable compared with glass, which is exactly what a product aimed at children needed.
A lunchbox regular
The built-in straw, designed to puncture the foil at an angle, meant no cup or opener was ever needed, which is a large part of why it became a default lunchbox drink for generations of children. UK flavours typically run to Orange, Blackcurrant, Strawberry and Tropical, and recipes have shifted to no-added-sugar formulations in recent years, largely driven by the UK's Soft Drinks Industry Levy, introduced in 2018.
