Packaging Sticker That Monitors Product Temperature Changes

Products that are meant to be kept frozen or refrigerated can sometimes experience temperature fluctuations in the supply chain, so this packaging sticker has been developed to help track if it happens.

The sticker has been developed by scientists athletes the Korea Research Institute of Chemical Technology and utilizes polymer nano fibers that will neatly intersect when kept cold.

If warming or temperature variance is experienced, however, then the film on the sticker will become opaque and allow the image underneath to be seen and let the retailer or consumer know that the product might not be suitable for use.

The packaging sticker is a low-cost solution that could help to make the process of product tracking easier.
