General:

Food is a Timestrip® temperature indicator that shows how long your product has been above refrigerated temperature (5 ˚C/41 ˚F).Inert until activated and self-adhesive, it can be stored

at room-temperature then stuck to a product or package when needed (see Appendix 1 for adhesive details). It is single use and indication is irreversible. It is splashproof and there is an expiry date on each pack shipped.

How to use:

The indicators are completely inert prior to activation and can be stored at room temperature.To activate Food the surrounding temperature must be at or above the threshold temperature of 5˚C so that the blue liquid can be released from the button. Fully squeeze the button and check that the word ‘On’ appears.If not, immediately re-squeeze the button fully. Within 2-3 minutes of activation, place the indicator below its STOP temperature for a minimum of 1 Hour so that the liquid freezes and the indicator is fully conditioned and ready to use. If the carrying card or the product to be monitored is already at or below the STOP temperature then the indicator can be stuck directly to it by removing the adhesive liner on the back.
