Capri Sun was introduced in 1969 by Rudolf Wild in Heidelberg, Germany. The most revolutionary aspect of the drink was not the juice itself, but the 'stand-up pouch' packaging. Made of a laminate of plastic and aluminum foil, the pouch was designed to be lightweight, durable, and resistant to oxygen, which helped preserve the juice without the need for artificial preservatives. This was a significant departure from the heavy glass bottles or tin cans of the time. The drink gained massive popularity in the 1980s, especially in the United States, as it became a staple of school lunchboxes. The iconic orange-and-silver pouch design and the challenge of piercing the straw through the designated spot became cultural touchstones for a generation of children.
