The new-look portfolio, which rolls out this week, features a more prominent logo and is designed to create consistency across the Fridge Raiders, Mighty Bites, Smoked Pork Sausage and Turkey Rashers ranges.
A colour-coding system has also been introduced to make it easier to differentiate between flavours.
The revamp signalled the start of the brand's "biggest-ever marketing investment", said Anthony Wilkinson, marketing manager at Kerry Foods.
TV and press activity is due to kick off next month.
Kerry this week announced its pre-tax profits for 2009 were up 4.8% to 252m, although turnover slipped 5.6% to 4.5m.
However, sales at its consumer foods division fell by more than 6% on a like-for-like basis.
