Traditional thermal cargo covers can significantly contribute to airfreight cost due to their bulk and weight. “A thickly-insulated cargo cover, or even a bulky ‘bubblewrap’ type material, can easily be adding more than €60 to the intercontinental air freight cost of a typical, volumetrically-charged, Euro pallet”, says Malik Zeniti of DuPont, manufacturer of the thin and light Tyvek range of air cargo covers. “With bulky products such as these you are effectively paying to ship air.”
Studies have shown that switching from traditional, and typically cumbersome, thermal blankets to DuPont Tyvek air cargo covers could provide savings of around 12.5 per cent on total air freight charges. This is because Tyvek covers work on a combination of heat reflection and air exchange principles in order to manage temperatures and prevent out-of-range excursions, as opposed to the voluminous insulation typical of traditional covers.
In all cases, the optimum cost-saving solution is one where both the weight and the volume of the cargo covers are low — which is exactly what Tyvek cargo covers are designed to deliver according to Zeniti. “By substituting a Tyvek cover you are adding practically zero bulk and less than a kilo in weight and, of course, the covers themselves are often a less expensive alternative in the first place,” adds Zeniti. “And with Tyvek you are not paying for the storage and carriage of heavy, bulky, covers, nor for their labour intensive, time consuming utilisation. Tyvek covers require minimal storage space and the covers can be fitted or removed in as little as 60 seconds.”
