The code, which is only revealed when the polyester lid is peeled back, is the first of its type to be used in the UK dairy market. Chadwicks has printed 19 different lid designs for the Yeo Valley range.
Each lid has its own unique 10 character code that customers enter online via the Yeo Valley website for the chance to win a VW campervan.
Dan Rusga, Marketing Director from Yeo Valley said: "When Chadwicks first came to us with this innovative printing technique we were quick to identify an opportunity to apply it to our product competitions. We've been very impressed with Chadwick's technical expertise and their ability to come up with unique lidding solutions whilst not compromising on quality."
Yeo Valley is the largest organic brand in the UK and is an independent, family−owned farming and dairy business based in Blagdon, North Somerset.
John Chadwick, Managing Director at Chadwicks, said: "You can't stand still in our business and we're always looking at ways of improving our product offering and coming up with new and innovative ideas for customers. We've spent a long time perfecting this particular technique and it's great to see it working so well for one of our most valued customers."
