Consumer concern has led Kraft Food to install a transparent plastic bottom on packs of the popular children's natural juice drink Capri-Sun.
Announced in May 2014, the new bottom will feature on packs in the US, to allow parents to check the colour and consistency of the juice pouches for the presence of mould. It is made of a two-ply laminate, with the inner surface cleared for food contact purposes.
It has taken one year to develop. Kraft admits that, because Capri-Sun uses no artificial preservatives, it is possible for mould to form in the packaging, especially if the pouch is punctured and air enters. In some instances mould in Capri-Sun pouches has grown into a shape resembling a worm. Consumers have then posted and circulated pictures of these on the Internet. Plastic bottoms will also now be installed in all standard size packaging of the whole Capri-Sun range, including fruit juice, vegetable juice and flavoured water lines. To counter the problem the firm did consider making the back of the pack transparent, but found this posed additional manufacturing problems.
Besides checking the clear bottom, Kraft also suggests drinkers squeeze the pouch before opening to check it has remained airtight.
