Polar Thermal Products, a manufacturer of insulated systems for logistics, has launched thermal liners, or blankets, for aircraft containers, or Unit Load Devices (ULDs).

Thermal blankets, the company said, are effective at protecting goods against temperature spikes during high risk periods such as when ULD's are sitting on the tarmac awaiting loading.

A company statement said the liners have been tested by logistics companies and adopted for pharmaceutical shipments at temperatures ranging between 2C and 8C. They are also being tested with a major food company in order to reduce their perishable losses.

"Hardening attitudes of the regulatory authorities have highlighted the demands made on freight companies involved in cold chain movements. Adopting the use of thermal blankets reduces the risk of falling outside temperature limits," said Polar sales chief Peter Lockett.

"Having quick access to thermal blankets on rental is seen as a useful service if moving occasional goods or even if trials are required. It means that companies can pitch for business with confidence," he said.
