Food waste is a mounting global concern, and with the planet’s population continuing to grow, so too does the pressure on food systems. While countless initiatives are aimed at reducing waste at various points along the supply chain, one of the most innovative and promising developments in recent years has been the rise of smart labels.
These high-tech stickers, tags and packaging components are transforming the way consumers, retailers and producers approach food freshness and shelf life, helping to significantly cut down on unnecessary waste.
Go deeper with GlobalData
Each year, the world wastes around one-third of all food produced—about 1.3 billion tonnes, according to the Food and Agriculture Organization of the United Nations.
In the UK alone, households are responsible for over 70% of this waste, much of it driven by confusion over expiry dates and a general lack of clarity about when food is truly no longer safe to eat.
Smart labels offer a powerful tool in turning this trend around.
What are smart labels and how do they work?
Smart labels refer to a range of sensor-based or chemically reactive packaging technologies that monitor the condition of food products in real time.

By GlobalDataRather than relying solely on printed “use by” or “best before” dates, which are often conservative and not tailored to actual storage conditions, these labels give dynamic, accurate information about a product’s freshness.
Time-temperature indicators (TTIs) are one example. These small stickers change colour depending on how long a product has been exposed to temperatures outside the recommended range.
If a chilled product is left out too long during transport or at home, the TTI will show it, alerting the consumer to a potential drop in quality or safety.
Other forms of smart labelling use gas sensors to detect spoilage indicators like ammonia or hydrogen sulphide, which are emitted as food begins to decompose. Some labels even use pH sensors or barcode-linked apps to provide detailed updates via smartphones.
In some supermarket trials, electronic RFID tags and QR codes have been paired with real-time tracking systems, enabling producers and retailers to monitor inventory and reduce waste at the stockroom level.
Empowering consumers and retailers alike
One of the biggest advantages of smart labels is that they shift the focus from arbitrary dates to actual product quality. This helps consumers make more informed decisions, reducing the likelihood of perfectly edible food being thrown away.
Surveys in the UK show that one of the main reasons people discard food is uncertainty about whether it is still safe to eat. With smart labels giving visual, real-time cues about freshness, the guesswork is eliminated.
A label that indicates a product is still fresh—even if the “best before” date has passed—can encourage more sustainable consumption habits.
Retailers, too, benefit from these technologies. Shops can use smart labels to optimise their inventory management, reducing the number of items that go unsold and end up in bins. Products nearing the end of their shelf life can be quickly identified and marked down, or donated while still safe and edible.
Some supermarket chains have begun trialling AI-enhanced smart labels that recommend when to offer discounts on items based on freshness data, ensuring less waste and better margins.
Challenges to widespread adoption
Despite their clear advantages, smart labels have yet to become mainstream, largely due to cost and scalability challenges.
Many of the most advanced sensors and indicators remain too expensive for widespread use, especially for low-margin goods. Smaller food producers may be particularly hesitant to adopt smart packaging unless costs come down significantly.
There are also regulatory and consumer education hurdles to overcome. In the UK and across the EU, labelling laws require certain fixed date markings, even if smart labels are in use.
Changing these regulations to accommodate dynamic freshness indicators would be a significant, albeit necessary, step.
Public understanding is another piece of the puzzle. While smart labels are user-friendly in design, they represent a shift in how we think about food safety and expiry. Clear communication will be essential to ensure consumers trust and embrace these innovations.
Some companies are already incorporating educational campaigns into their packaging to explain how the labels work and what the indicators mean.
A smart future for food preservation
As technology becomes more affordable and public awareness grows, smart labels are poised to become a standard feature in food packaging.
Their ability to reduce waste, enhance safety and even cut carbon emissions (by reducing the need for refrigerated transport and storage) makes them a critical part of the future of sustainable food systems.
Major players in the food industry are investing heavily in smart packaging research, and government-backed trials in the UK, Scandinavia and Asia are showing promising results.
With the right policy support and investment, smart labels could soon move from novelty to necessity, changing the way we think about food—and waste—for good.
Ultimately, the most powerful aspect of smart labels is not just their clever chemistry or tech-forward design, but their potential to foster a more conscious, resource-respecting culture. In a world where so much still goes to waste, even the smallest sticker can make a lasting difference.
