Tyvek® Cargo Covers Pharmaceutical Technical Study    

Purpose:
Evaluate the performance of Tyvek® Cargo Cover to protect simulated Controlled Room Temperature pharmaceutical product through a simulated route in which the product is exposed to solar radiation and both hot and cold ambient extremes.

Method:

  • Test sample – Euro sized pallet protected with a low emissivity Tyvek® Cargo Cover
  • Control sample – Euro sized pallet with no protection, current case
  • Pallet configuration – 18 boxes (15” x 15” x 15”) stacked 3W x 2D x 3H
  • Low-to-medium thermal mass (110 liters water, liqui-packs). Simulated product – saline-filled vials.
  • Temperature probes inserted into vials. 
  • 7 data loggers (21 temperature probes) were installed per pallet at typical excursion spots.
 
Route Profile - Simulated actual pharmaceutical route, leaving northern hemisphere in summer with solar radiation and hot ambient extreme exposure, landing in southern hemisphere in winter with cold ambient extreme exposure.
Test Data: Product Temperature (Top)
Starting & Ending Product Temperature (Top) - Excursions shown in red text.

Test Data:

  • Please see second image on left

Result:

  • ZERO temperature excursions with Tyvek® vs TWO excursions for Control sample
  • 10°C (18°F) reduction in peak temperatures on tarmac in summer conditions vs control
  • 6°C (11°F) improvement in peak temperatures on tarmac in winter conditions vs control
  • Tyvek® Cargo Cover moderates rate of heating and cooling of product vs control

Benefits Demonstrated:

  • NO excursions despite 3 hour exposures to solar radiation + hot and cold ambient extremes
  • Tyvek® Cargo Cover prevented the product from freezing (while control did not)

Tyvek® Cargo Covers provide excellent “all-in-one” protection from solar radiation AND ambient extremes (hot and cold),  helping you conserve your stability budget.
