When shipping biological and chemical samples, pharmaceuticals or perishables in frozen states, having a viable alternative to dry ice is essential — it is a substance that is viewed as being hazardous in many regulatory compliance quarters.
Tempack’s Rigid Frozen Pack overcomes this and other issues, while offering a host of other preferable thermal transportation benefits in the process.
While dry ice is capable of maintaining frozen and deep-frozen temperatures for long periods, it sublimates into carbon dioxide gas. As a result, consignors need to apply very specific dangerous goods labelling and handling instructions on such shipments. Furthermore, logistics providers have to be mindful of the legal limitations placed on dry ice in aircraft cargo holds. These restrictions can easily hamper air transportation plans.
No such problems with Tempack Rigid Frozen Packs. Manufactured using high-density polyethylene (HDPE) and eutectic gel as a coolant, these hardy, temperature control bricks are able to guarantee the maintenance of negative temperatures for frozen products. Unlike water which melts at 0ºC, phase change in our Rigid Frozen Packs occurs at -21ºC, allowing frozen temperatures to be maintained over extended periods. Depending on the exterior packaging selected, they will do so with autonomy of up to 4 days.
