Latest Tyvek® Cargo Covers on show at leading London logistics event

The latest Tyvek® Xtreme™ W50 Cargo Cover from DuPont will be on show for the first time at Europe’s largest cool-chain gathering, the 16th IQPC Temperature Controlled Logistics event in London.

The new product builds on the huge success of the original Tyvek® Solar™ W10 and Tyvek® Solar™ W20 Cargo Covers and, in addition to providing outstanding screening from solar radiation, extends the performance envelope of the range to provide beneficial cold temperature protection.

“The Tyvek® Xtreme™ W50 has been designed to bridge the gap between single-skin thermal covers and bulky thermal blankets,” explains Yves Le Minor, European Business Development Manager for the Tyvek® Cargo Cover range. “It incorporates a special fleece insulation laminated to a tough overlay of non-woven Tyvek® material which includes a silver low-emissivity coating. This configuration is much better able to maintain its thermal properties and withstand physical manhandling than plastic film and bubble-based alternatives."

The use of a fibrous insulation rather than one based on air bubbles was no accident as DuPont Technical Specialist Alain Weimerskirch explains: “We investigated very carefully the various technical options open to us in order to insulate the new Tyvek® Xtreme™ W50 Cargo Cover. We found that covers using insulation based on air bubble laminates are too easily damaged in use and this compromises their performance. They also have a low thermal capacity which reduces their ability to respond to rapid temperature swings and at the same time, being impermeable, they do not permit an exchange of air between the inside and outside. This mean that bubble-based covers have a limited ability to cope with conditions of high relative humidity. Fibrous insulation, on the other hand exhibits favourable properties in all these respects.”

The latest Tyvek® cargo cover retains the hallmark breathability property for which products made from Tyvek® are renowned. This inherent air permeability helps control humidity levels underneath the cargo cover in order to stop the formation of damaging condensation. Condensation is an inevitable by-product when goods are moved from hot to cold environments and where products and packaging release moisture when being moved from cold to hot environments. “Protecting pharma products from excess humidity and unwanted moisture is an increasingly important requirement for cargo covers,” says Le Minor. “We are experiencing much greater interest in this product feature as its benefits for pharma transportation become more appreciated and as multi-modal shipping practices evolve. The GDP regulations are explicit in their need for humidity risks to be controlled during transportation and storage and we will shortly be publishing a White Paper on this important topic.”

The Tyvek® Xtreme™ W50 Cargo Cover combines high performance with low-weight and low-bulk in a fast-fit format. They provide tamper-protection, are fully weather-resistant 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 sleeved in as little as sixty seconds.

The new covers have been the subject of stringent testing at DuPont’s state of the art technical facilities in Europe, Asia and North America. Rigorous qualification exercises in the field have also been conducted and a Performance Qualification Report relating to the Tyvek® Xtreme™ W50 will be available for inspection at the Tyvek® booth.

Le Minor points out that it is important to consider the technical and commercial pedigree of suppliers when it comes to selecting products to protect health and life-giving product. “There are many suppliers of thermal cargo covers now on the market but when a customer is seeking a top-quality, fully tested and pre-qualified cargo cover from a highly respected global manufacturer the options diminish rapidly” he explains. “DuPont is a world leader in protective fabric technology with the technical resources and international presence to provide the support and service increasingly being demanded in today’s complex operating climate.”
