Billington Cartmell, the integrated agency that devised the original 'Dreamz' concept, is again managing the campaign.
It will run throughout the autumn across 168m packs of beans, soups, pasta, salad cream and tomato ketchup, offering family-focused dream prizes.
The prizes also include home entertainment and electrical goods from Play.com and one cash prize of £10,000 for those entering online.
Consumers can see if they have won anything either by checking under the lid of the special packs or by entering a unique code on the back of the pack into the dedicated .
Kim Robinson from Heinz central marketing said: "The campaign centres on the recognition that families have a range of dreams as diverse as Heinz's range of foods -- and Billington Cartmell has, once again, provided strong creative and wonderful partners to support us in Dreamz 2008."
Last year's campaign generated more than 340,000 competition entries.
