How OnVu™ works

A variety of OnVu™ indicators are formulated to cater for the different spoilage behavior of food and beverages. These tailored indicators are consistently accurate in recording the freshness of the produce as both length of time and temper-ature are measured. This is much more reliable than the “use-by date” rule of thumb.

As the consumable goods are packaged, an OnVu™ TTI is added and activated using a UV light source. An example of an OnVu™ label can be found on the left flap of this flyer. A filter is then added over the label to protect it from deliber-ate recharging. An example of the filter can be found on the right flap of this flyer.
