Smart label monitors food shelf life

A new smart label that allows food processors to monitor the shelf life of products packed with modified atmosphere gases has been launched by Finland-based UPM. The Shelf Life Guard turns from transparent to blue, informing the processor, distributor, or consumer that air has replaced the modified atmosphere gases within the package.
UPM says the label will help companies to monitor and self-assess produce’s shelf life, allowing them to maintain quality and avoid recalls. It could also be used to give consumers directions on use and product information.
UPM’s intelligent packaging product family also includes Freshness Guard, which signals deterioration in poultry or fish products in modified atmosphere or vacuum packages.
