LIMITmarker Reversible 18°C

Self-adhesive reversible temperature indicator

Many products require refrigeration to maintain their efficacy, but are recommended for use at room temperature for optimal performance. Zebra LIMITmarker Reversible 18°C indicators can be applied to the primary packaging of products, providing a clear visual sign when a refrigerated product reaches 18°C. The indicator is solid blue when cold (at or below 8°C), then changes color and reveals “OK” when it approaches room temperature (18°C, plus or minus 2°).

LIMITmarker Reversible 18°C Indicators

Easy to understand

The indicators are solid blue at refrigerated temperatures, but they change color to reveal a clear “OK” message when they approach room temperature. This indicator is reversible, and the label darkens to solid blue again when refrigerated.

Easy to apply

The indicators are 16 mm x 10 mm self-adhesive labels, easily applied to the primary packaging of products, where they can be viewed and intuitively understood by users.

Enhanced satisfaction

When a product performs best at room temperature but must be refrigerated to maximize its shelf life, it’s hard to know when it reaches room temperature and is ready for use. Reduce instances of user dissatisfaction with your product’s performance by providing visibility into its temperature with LIMITmarker Reversible 18°C indicators.

Improved user experiences

Visible temperature indicators are especially helpful where users are concerned about the discomfort associated with using a refrigerated product while it is still cold. Zebra LIMITmarker Reversible 18°C indicators help manufacturers provide a unique visual cue on their product packaging that can enhance the user experience and help overcome reluctance associated with discomfort from using the product when it’s too cold.

RedDot Design Award

Zebra LIMITmarker Reversible 18°C indicators clearly show when a refrigerated product approaches room temperature.

Adhesive Strength

Permanence of Adhesion Single use application. Indicators are intended to adhere permanently once applied to a surface. Removal may cause damage, and indicators will not perform as specified.
Surface Compatibility Indicators may be applied to a wide variety of surfaces, including paper and paperboard (e.g., primary or secondary packaging), polyester film, and glass. They have shown suitable adhesion to metal surfaces and plastic films such as polyethylene (PE), polypropylene (PP), rigid polystyrene, polyvinyl chloride (PVC) and polycarbonate. Due to the variable nature of these materials and the effect of printing and other surface treatments, you should always evaluate the suitability of your package material for application of the indicator.
Application
Considerations
Affix the indicator to a clean, dry surface at refrigerated or room temperature. Adhesion of indicator may be affected by affixing it to a surface that is extremely rough, oily, wet and/or frozen.
