Packaging giant Tetra Pak will unveil new milk cartons that will change colour when left out of the fridge for too long, it was reported.
The smart cartons will be the latest innovation to improve food safety from the Swiss-based company as demand for sustainable packaging increases.
According to the Financial Times, the company is developing a chip that can be embedded in the cartons while containing information about how long the product has been out of the fridge.
The chip could then be scanned by a mobile phone to show details about the farm and cow that had produced the milk, in a partnership with Brazilian food co-operative Aurora.
Tetra Pak announced today that its net sales were up five per cent to EUR10.36 billion (£8.6 billion) over the last financial year.
In 2011, the company launched the first aseptic milk carton as well as supplying packaging for more than 76 billion litres of milk, juice and other drinks.
“We are committed to supporting our customers, retailers and suppliers over the long term and will continue to invest in products, services and facilities that look beyond tomorrow, while also making sure we deliver what is needed today,“ said Dennis Jönsson, president and chief executive of Tetra Pak.
He told the FT: "Resources are becoming scarcer and, with costs being higher, it is important to ... do more with less."
The firm will also be taking part in the Anuga FoodTec trade fair in Cologne, which starts tomorrow.
In a statement ahead of the four-day fair, Tetra Pak said: "As a part of a changing market landscape, there are new challenges and demands to be met, such as legislation on one side and producer/customer demands, consumer needs, product shelf-life, distribution requirements, and environmental impact on the other side."
