We produce and sell two variations of CheckPoint® labels: CheckPoint® I and CheckPoint® III.  Here are the significant differences:
 

Characteristic/Type	CheckPoint® I	CheckPoint® III
Kinetic Properties	Adjustable to various different types	Limited to main kinetic type for food and pharmaceutical applications
Label Technology	Enzyme reaction leading to pH change in contained fluids in label	Diffusive reaction leading to pH change in printed dot on label face
Application and Activation	Single label requires bursting of fluid pouches and mixing...adhesive label	Dual labels are merged into single active label at the activation step
Color change	whitegreenyelloworange-red	amberorangepink-magenta
Applications	Special situations; custom formulations; food industry "behind the counter" and freezer applications	High speed activation and attachment to packages; high volume, low cost; consumer; MAP seafood
Storage	Must be frozen when not in use; slower response at high, abusive temperatures	Can be stored at room temperature; rapid response at high, abusive temperatures
Most significant characteristics	Custom formulation; rapid change in color at endpoint	High reliability and low cost

CheckPoint^® III Product Details

This diagram shows both the Activator Label and the CheckPoint III label itself.

Both labels can be handled like any normal adhesive label, and are supplied in rolls of 5,000 labels on standard 3" cores with a transparent plastic backing liner.  There are no hubs supplied with the label rolls. 

The time-temperature function becomes active only when the Activator label is positioned over the target zone as shown.  We can configure CheckPoint III with a different size and with different consumer advisory messages for customers who qualify with volume purchases. 

Lead time for custom formulation of label response is 3-4 months.  Lead time for different sizes and label appearance modifications is generally one month or less.

Shipping is not included in the label pricing.  There are no temperature or other requirements for special shipping.

Please call us for technical details of available types and time-temperature characteristics.

CheckPoint^® I Technical Details

CheckPoint® I labels are manufactured to order at our Malmö, Sweden location.  They must be transported by expedited service, and are packed with solid refrigerant in an insulated container.   All shipping costs are included in the purchase price of the labels.  They are supplied on standard 3" cores with cardboard hubs.

Lead time for a custom formulation is at least three times the standard time run for a desired label type.  For example, if you are seeking a label with a time run of 14 days at 4°C, then the lead time for obtaining test samples would be 3 x 14 = 42 days.  We will only custom formulate for orders of sufficient size to justify the work of formulation.  Many standard types are available.
