Smart label for the cold chain

Abstract/Technology Overview

The smart label is a low-cost solution for monitoring temperature environments on individual packages, cartons, and pallets being stored and transported in the cold chain. Markers on the smart label are irreversibly changed when extended temperature abuse has taken place, so that manufacturers, distributors and retailers are able to audit and properly secure their cold chains, leading to reduced product damage and improved product quality.

Technology Features, Specifications and Advantages

The smart label makes use of tiny amounts of inks which are activated by changes in the temperature environment. These food-safe temperature activated inks are encapsulated within the smart labels and never come into contact with the underlying food, even though they have been certified bio-compatible with the food industry by global regulators. The activator ink will erase certain markers on the labels when temperature abuse has taken place. Markers that have been erased cannot be recovered by re-chilling the product. 

The ink in the smart label is customisable depending on the product temperature requirements, ranging from -30 below zero, to +25 degrees Celcius.

The key advantage of the smart label is its low cost. As such, labels can be affixed onto individual food or pharma products, as well as transport pallets and cartons for high-level visual inspection especially during handoffs between different logistics providers. The label also has the ability to track cumulative temperature damage to products, unlike data loggers or temperature monitors which only take spot measurement readings. 

Manufacturers of food and pharma products from Singapore can also use the smart label to secure their exports to the regional and global markets. This is especially relevant for manufacturers of Ready-to-Eat food products where minimal cooking is required before consumption. A product secured by the smart label provides reassurance to consumers that the product has been properly handled during transport and storage in the cold chain, and is safe for consumption.
