DuPont unveiling third-generation Tyvek® Cargo Cover at the 'LogiPharma' supply chain event in Montreux 19th - 21st April 2016 

The new Tyvek® Xtreme™ Cargo Cover is designed to protect pharma goods that are intolerable to low temperatures for enhanced temperature stability during transport.

DuPont has extended its market-leading range of Tyvek® cargo covers with the new Tyvek® Xtreme™ W50 product. Fitted with a proprietary insulative layer, Tyvek® Xtreme W50 retains the reflective and permeability characteristics of the existing Tyvek® pharma products while extending both the hot and cold temperature performance span. The result is a product which can be used in CRT categories where there is a need for frost as well as heat protection as well as an effective component in packaging systems for 'cold' temperature products.

"Designed to 'bridge the gap' between single-skin thermal covers and bulky thermal blankets, the Tyvek® Xtreme™ is in a class of its own,"says Yves Le Minor, European Business Development Manager for the Tyvek® Air Cargo Cover range. "The class-leading reflective performance of Tyvek® combined with the new product's mass thermal barrier creates a protective envelope marrying exceptional performance with affordability. By introducing a 'thermal flywheel' effect, the new insulated cover is particularly suitable for intercontinental CRT freight lanes, especially those with transient exposures to very low ambient temperatures and in cases where there is a potential for sizeable temperature swings."

By combining a low-emissivity silver lining and highly reflective outer surface with a high efficiency thermal layer, the new cover performs both as a radiant shield and a conduction barrier. It has also been engineered to be vapour permeable yet fully weather-resistant, allowing protected pallets to evacuate condensation by 'breathing' whilst, at the same time, providing dependable protection from rain, snow and wind. "No other commercially-available cargo cover on the market successfully combines these performance characteristics," says Fred Fleury, Marketing Manager at DuPont, "This makes the new Tyvek® Xtreme™ Cargo Cover a particularly reliable option when it comes to protecting 'room-temperature' pharma products. It is also designed to provide supplementary thermal protection to passive containers and to rigid, uninsulated ULDs as a component part of qualified systems."

The special fleece layer used in Tyvek® Xtreme™ is more robust than some insulants such as bubble film which can be prone to puncture, tearing and abrasion damage during the harsh handling that can occur during multimoda transit steps. "The Tyvek® Xtreme™ comprises a strong, continuous-filament, fibrous insulation layer laminated to a tough overlay of non-woven Tyvek® material," explains Yves Le Minor. "This configuration is better able to maintain its thermal properties and withstand physical manhandling than thin plastic film and bubblebased alternatives."

Superior temperature control characteristics are not the only advantages of using Tyvek® Cargo Covers. They are very strong, tear-resistant, light in weight and very fast to fit. They provide tamper-protection, are fully weatherresistant and offer a highly effective barrier against air-borne contamination such as dust, pollen and bird droppings. Tyvek® covers are available for the majority of standard air freight pallet sizes and are very quick to install and remove. A typical pallet or ULD can be protective-sleeved in as little as sixty seconds.
