PakSense Inc., Boise, Idaho, has launched XpressPDF, a new temperature monitoring label that records the time and temperature of food, vaccines, and pharmaceuticals during distribution and storage.

The labels feature a USB connection which can be plugged directly into the USB port of a computer, according to a news release. Once the label is connected, it creates a PDF file that documents the time and temperature history of the product.

About the size of a sugar packet, XpressPDF Labels do not require packaging modifications. A waterproof form on the label allows cold chain monitoring at the pallet, carton, and individual product level, according to a news release.

The temperature sensor on the XpressPDF Labels takes a surface read of the object it is attached to, then flashes to notify the user to download the data collected through the USB connection.
