Unilever’s Hellmann’s mayonnaise brand is trialling a special edition ‘Smart Jar’, which can tell the consumer when their fridge is at the right temperature and potentially prevent food waste.
By using temperature-sensitive ink, the label design changes when the fridge is set below 5℃ to reveal a hidden layer. Certain foods can last up to three days longer in a fridge set below 5℃ (vs 7℃), including milk – one of the most wasted food products in your fridge.
Trial prototypes with a label design from illustrator Ellen Porteus have been sent to consumers, food waste campaigners and influencers to raise awareness of food waste during Food Waste Action Week.
“We know how important it is to make the most of the food you buy. At Hellmann’s we’re constantly looking to help consumers reduce food waste and save money and think Smart Jar is an innovative way to get people talking about – and solving – this massive problem,” said Rachel Chambers, Senior Marketing Manager of Hellmann’s.
