New product helps protect temp-sensitive cargo

A new range of air cargo covers designed to protect temperaturesensitive products from solar radiation has just been launched by Johannesburg-based Marshall Hinds, the SA distributors of DuPont products. This Tyvek range of air cargo covers has highperformance protective membranes protecting food, pharmaceuticals and other perishables from temperature damage during transport, according to Yves le Minor, key account manager at DuPont. He also suggested they were a must in the African climate. “Solargain effects can easily send the temperature of exposed pallets soaring,” he said. “Products and produce are often exposed unintentionally to intense sunshine conditions for long periods, especially during loading and unloading operations.” Made from low conductivity Tyvek fabric, the covers combine three complementary operating mechanisms. The white micro-fibre exterior surface provides a highly ref lective barrier to external solar gain; the metallised inner surface presents a ‘low-e’ emissivity barrier to help maintain core package temperatures; and the material’s inherent vapour permeability controls harmful condensation. Compared to insulated thermal blankets, these Tyvek air cargo covers don’t inhibit cooling where products must be pre-cooled or need to cool down after unwanted exposure to heat. They are also strong, tear-resistant, f lame retardant, lowbulk and light in weight.
