Asparagus Field Trial — Performance Evaluation


Evaluate the effect of Tyvek™ air cargo covers on quality and shelf life for air-shipped fresh green asparagus from pack-out in South America through distribution and retail in the United States.

Trial Protocol

  • Test sample – UK/US-sized pallet protected with a Tyvek™ air cargo cover – classic white
  • Control sample – no protection, industry standard
  • Product temperature, air temperature and humidity measured continuously at strategic locations within pallet from pack-out through distribution. Average temperature is reported.
  • Product quality and shelf life assessed at points throughout journey from pack-out through retail.
  • Product quality measured on 5-point scale at third-party lab based on length, weight and asparagus appearance. Appearance factors were: decay, compact/open tips, tip softness, and color.

Test results


  • The use of DuPont™ Tyvek™ air cargo covers demonstrated an average reduction in peak temperatures of 8° to 9°C vs. control. 
  • The use of DuPont™ Tyvek™ air cargo covers maintained the desired high humidity environment during air transport by ensuring zero moisture loss. The uncovered product recorded a 1.5% product weight loss due to loss of relative humidity.
  • The temperature and humidity management benefits of Tyvek™ air cargo covers delivered a 40% improvement in shelf life and substantially higher “as received” asparagus quality at the distribution centers and retail levels.
