Dupont introduces triple action air cargo covers to keep pharma cool
DUPONT's Tyvek Air Cargo Covers have been introduced to offer a dependable, affordable means of complying with the new EU GDP (good distribution practice) for pharmaceuticals, reported Norwich-based Packingeurope magazine.
They are developed to deal with heat flow mechanisms at work in the fluctuating air temperatures in air cargo logistics, said Dupont.
Made from low conductivity fabric, they work through a white micro-fibre exterior providing a sun reflective barrier while the metallised inner surface presents a "low-e" radiant barrier to help maintain core temperatures, said Dupont.
"When designing the covers we analysed the nature and incidence of pharma coolchain temperature spikes and dips together with the physical heat loss/gain mechanisms involved," said Dupont development manager Malik Zeniti.
"It is this multi-mode approach the cargo covers their temperature control characteristics," he said.
DuPont findings also found that some packaging products serve to increase the effect of solar radiation temperature gains during transport "often to unexpectedly high and dangerous levels".
Said Mr Zeniti: "While serving as a barrier to rain and snow, the inherent breathability of the Tyvek reduces the possibility of packaging or label damage resulting from condensation. This quality is of particular importance where goods must be protected from freezing since excess moisture can exacerbate cooling effects and is further guarantee of temperature stability during transport."
