Technology for easy use

Ease of use

Timestrip® Time indicators are small, tamper-proof, and inert prior to activation. Timestrip® Time windows are white before activation.

Activate at room temperature, no pre-conditioning is required.

Clear Activation

Timestrip Time indicators are small, tamper-proof labels that are irreversibly activated by finger pressure.

For blister on top products: Firmly squeeze the blister on top of the indicator.

For blister on bottom products: Firmly squeeze the blister on the bottom of the indicator.

Once activated, an activation line appears in the window and continues to fill the window with colour. The Timestrip can be directly applied by removing the adhesive liner on the back.

Simple Communication

Once ‘ON’ a safe dye migrates along a display window, showing elapsed time in a range from days to 12 months.

The patent protected technology has no moving partsand requires no power source.

How long has a product been in use?”
Knowing how long a product can be used after opening is important. Seeing how long is left before replacement is better. Timestrip offers a visual cue that reminds customers to replace, service or maintain a product.


Timestrip Time indicators are perfect for products that have:

  •  A limited active life
  •  No accurate way of identifying when the effective time has passed
  •  A built-in component that needs to be replaced at regular intervals
  •  Service or maintenance schedule that will impair performance if not followed
  •  Compliance related warranty
  •  After market service team that needs to be kept busy
  •  End users that don’t contact you to renew products / services
  •  Compliance rules for reading / replacing

Consumers benefit from noticeably better performance and ultimately a longer-lasting and more efficient appliance. Brands benefit from increased customer satisfaction and brand loyalty, higher levels of repeat purchases and enhanced brand value.

See how Timestrip time indicators were customized especially for 3M Filtrete water filters on our case study page here.

Use Cases


Timestrip’s unique ‘end-of-life’ indicators clearly show how long a filter has been in use.They prompt consumers to replace or service filter components, giving them improved appliance performance and encouraging higher levels of purchases and service use.

With minimal cost to the brand, there are many benefits to adopting Timestrip indicators, especially when integrating it into product packaging. 3M (see case study) and Whirlpool (see case study) are some of the leading brands who have added value to their filter products by integrating the technology.

Consumers complying with recommended replacement cycles purchase filters regularly, resulting in higher repeat sales. They need no batteries, can not be reset once activated and have no shelf-life requirements, ensuring more reliable monitoring of service cycles than their electronic counterparts.


Timestrip time indicators have been used to alert healthcare staff when equipment such as hospital curtains are
due for replacement. These curtains and other semi-fixtures can carry bacteria and viruses, facilitating their transmission as individuals come into contact with them on a regular basis.

Filters for Personal Protection Equipment face masks require regular replacement to maintain their efficacy, and
time indicators can provide reassurance and alert staff when their supplies need to be changed.

Hand sanitisers are a familiar feature of healthcare settings these days, but after opening, they have a finite shelf life before replacement is required; Timestrip time indicators can be affixed at the individual product level and activated when opening.

Personal Care

Bacteria breeds as efficiently in cosmetics as anywhere else, but convincing consumers of the limited shelf-life of their make-up has always been a challenge. Now there’s Timestrip®, which when added to packaging, provide a clear visual indication of when an item should be discarded and replaced.

Using Timestrip® will encourage consumers to comply with replacement guidelines. The Period After Opening (PaO) symbol already tells consumers how long a product will last once it is open, but Timestrip® provides the crucial bit of information: when it was first opened. Adding Timestrips® to packaging or integrating them into the packaging itself offers consumers an easy to use, easy to read and accurate indication of how old their cosmetics actually are.

Lipsticks and glosses– repeated exposure to bacteria from the mouth and temperature fluctuations experienced during life in a handbag mean these products should be replaced regularly.

Mascara and eye pencils– with a shorter recommended shelf-life than other cosmetics, out-of-date products can produce infections.

Foundation– the liquid variety especially, as it has a shorter recommended PaO.

Natural or organic cosmetics– fewer preservatives or none at all means a shorter shelf-life than conventional products and potentially higher levels of bacteria.

Temperature-sensitive products– Timestrips accelerate at higher temperatures, indicating if a product’s shelf life has been affected by warmer conditions.


Dentists recommend changing your toothbrush every 3 months. Toothbrushes used after 3 months become worn and much less effective at removing plaque which can lead to dental health problems.

Timestrip® is a small, easy to read indicator that once activated will show the consumer when it is time to replace their toothbrush. Tesco partnered with Timestrip® to develop their very own Timestrip® toothbrush with a 3 month indicator inside the handle of the toothbrush.

The Timestrip® designed specifically for toothbrushes. Once activated, a red line will appear in the activation circle, followed by the word ‘on’. Once activated, the white strip will turn red and the word ‘replace’ will slowly be revealed. When 3 months is up, the word replace is fully visible and it is time to replace your brush.

The Tesco Range is complete with a bespoke designed brush with PP/PETG handle material, single injection elastomer and specific head profiles using DuPont filaments. The Tesco Timestrip® brushes come in a range of styles for your dental needs: The Timestrip® Massager, Deep Clean and Whitening. They are packed in branded PP tray in a coordinated colour.

The Timestrip® toothbrushes :
• Increase repeat purchases
• Improve customer confidence in the product
• Encourage trade up into premium tier brushes
• Help to educate consumers as to the benefits of a good oral health regimen
