Product quality can be compromised by exposure to elevated temperatures during transport, storage, or on arrival at final destination. Temperature indicators can be used to monitor and illustrate when a product has been exposed to temperatures above specified ideals. The indicators are often self adhesive and can be formulated to time anything from a few minutes to over a year and can be used for products where "Period After Opening" is more relevant than a "Best Before" date.
Timestrip (UK) Ltd produces a range of indicators that can accompany a product from the point of manufacture to consumption. An irreversible display will show a cumulative total of time the product has spent above critical temperature. This is particularly useful to monitor the last stage of the cold-chain journey where goods are often broken down into smaller consignments. The indicators are designed for single use, are accurate, inexpensive and can be adhered to pallets, boxes or even individual products. They are available for frozen, chilled and ambient products and can be customised for bespoke applications. They are easy to read and no specialist training is required. They can be mounted onto a backing card and can be used as a quality management tool to offer instruction and potential for sign-off at various stages along the route. The indicators have the potential to be used in air and water filters, toothbrushes, toiletries, cosmetics and certain food products.
Timestrip also produces a range of timer only products that can be attached to, or incorporated into, a wide range of items that need to be changed/renewed on a regular basis.

Potential Benefits

Key benefits include -
  • Reduces waste through identifying key temperature abuse areas of the supply chain, which can then be improved.
  • Easy to read - no specialist knowledge or equipment required to download information - visual check.
  • Can be used as a tool during trials to approve a new product for launch.
  • Monitors total journey from production to consumption.

Intellectual Property

All products patented.

Consultant View

Product quality and waste is effected by the various abuses of the supply chain, which includes temperature abuse. Time Temperature indicators have the potential to identify parts of the supply chain where temperature abuse is most prevalent. This not only gives the potential for the temperature abuses to be corrected, but also ensures that those involved become more aware of what can happen during the supply chain.
A further search of the REID database for additional Time temperature indicator entries is rcommended - for example the following entry titles -
"Oxygen Scavenging system uses a highly reactive oxygen absorbing system"
"Temperature sensitive metal based time temperature indicator"
