New film helps meat to keep its cool

Franco-American packaging firm Coldpack has launched a pioneering insulation film material, suitable for meat transportation in the UK.

The Airliner provides an effective thermal barrier. It comprises two layers of a special film, manufactured using DuPont Surlyn resin, which are separated by an aluminised honeycomb structure. This combination of material and design, when filled with air, creates multiple compartments known as 'baffles', which block calorie transfer to minimise all three types of heat transfer, radiation, convection and conduction.

The Airliner preserves the temperature inside the pack and the inclusion of coolants can be used to implement cold-chain distribution.
