Chips

Lightwaves, Oxygen and Water continually bombard our packs


12/39

30/04/2012 12

Light Waves can blast away the flavour -

they make it easier for oxygen and water to degrade the freshness

Metal helps to bounce the light away.

It also defends the chips from oxygen and moisture in the air...
