The clear packaging specialist linked up with Greencore Cakes & Desserts. Traditionally the protective collars were produced on folding boxboard with a grease resistant barrier to help minimise staining the printed branding and back of pack information.
According to Staeger, this format carried a risk that grease could wick through the board's raw edges.
For 2013 Asda wanted to eliminate this issue completely. The solution was to surface print on to food contact white re-cycled PET made from a minimum of 50% post consumer waste.
Staeger added that the development provides a complete barrier with "no possibility of wicking".
