Coldpack introduces Airliner insulation material

A new insulating film material for cost-effective temperature-controlled pharmaceutical transit packaging is being introduced in the UK by Coldpack.

Airliner consists of two layers of a special film manufactured using DuPont's Surlyn resin and separated by an aluminised honeycomb structure. This combination of material and design, when filled with air, creates multiple compartments - known as "baffles" - that minimise all three types of heat transfer: radiation, convection and conduction.

Airliner preserves the temperature inside the pack. The inclusion of coolants, such as gel packs or dry ice, inside the Airliner can be used to implement an efficient and controlled cold-chain distribution. The Airliner maintains products in packs of up to 70 litres either at ambient temperatures, typical product temperatures (e.g. +2° to +8ºC for pharmaceutical products) or at -18ºC for frozen products.

Contents are said to be protected during transit for 48 hours, but extended cooling systems are also available offering up to120 hours" protection.

The pack can be supplied flat, reducing logistics and warehousing costs. In addition, a Pira International life cycle assessment found Airliner has 40-50% less impact on the environment than polystyrene.
