1) Who are potential TTI customers?
The main potential customers are:
•    Supermarkets
•    Food manufacturers and transporters
•    Drugs, chemicals and biological materials manufacturers and transporters.

2) What do consumers think about TTI labels on food products?
Because consumers have ranked “Freshness” as the number one factor in their ratings of meat and other produce, the integration of a TTI on the packaging has been met with overwhelming positive response. According to a major university study, a TTI on a package would cause over 95% of shoppers to have more confidence in the freshness of that product, and over 96% would be more likely to buy a product with a TTI on it.

3) How much do TTI cost?
The price depends on several criteria, including the degree of customization, size and quantity. Typically, the price range is 1-2¢ each for quantities from 1 million upward.

4) How does the TTI activated?
The TTI is manufactured as two separated layers and activated when combine.

5) How long can the TTI be kept in storage before activation?
Until then they can be kept at room temperature, for months before activation.

6) What is the temperature-time range of the TTI?
The temperature range is from 10°F (-10°C) to 150°F (65°C).
The time range is from 10 minutes to 3 years (depending on the temperature)

7) How does the TTI applied to individual product?
High speed application of can be accomplished with any commercially-available automatic label applicator, just like other pressure sensitive self-adhesive label. The TTI labels adhere well to a variety of materials including films, plastic containers and glass.
Skyrad plans to develop TTI labels that can be printed using commercial printers.

8) Can the TTI be applied to a wet surface?
The best initial adhesion will be achieved on a dry surface. Condensation should be minimized by air knives installed just ahead of the label applicator.

9) How do we know whether a TTI is accurate and how much variability is there in a batch of TTIs?
We subject samples from every batch of TTI indicators to rigorous quality control tests. We maintain a certificate of analysis for every manufactured lot of product.

10) How do we select the right TTI for our product?
The TTI selecting process starts with the determination of the shelf life of your product for at least three storage temperatures. For example, recommended storage temperature for refrigerated product 35°F – 40°F (1.6°C – 4.4°C), an intermeddle one 50°F (10°C), and an elevated temperature, such as room temperature, i.e. 68°F (20°C). This information need to be supply to us by the customer.
Once a product’s shelf life curve is known, we can begin to understand the requirements for your product and offer some options for your testing and evaluation.
In case of vaccine or drug, WHO makes the decision on the appropriate category after considering the manufacturer itself and the stability data of the vaccine.

11) Does the use of a TTI eliminate the need for a “sell by” or “use by” date?
Consumer surveys have shown that shoppers prefer both a TTI and an expiration date to just one of the two. The use of a TTI eliminates the need to shorten the expiration date to allow for anticipated temperature abuse, a common industrial practice. A longer expiration date increases the display time and opportunity to sell a product.

12) Is FDA approval required for the use of a TTI on a food package?
No FDA approval required for the application of a TTI on a food package. The adhesives used in the TTI label meet FDA requirements for applications where incidental contact between adhesive and food is possible.

13) Will product returns increase once a TTI is implemented on consumer products?
Contrary to what many people think intuitively, experience shows that product returns will normally decrease once a TTI is implemented. The presence of a TTI increases the shopper’s confidence in the proper handling of perishable products bu the vendor. In some cases, returns may increase slightly temporarily while all the parties in the “cold chain” make the necessary modifications in handling procedures to assure proper product protection. In the end, everybody benefits from the increased accountability that the TTI label provides.
