How improved Air Cargo covers help maintain
quality in food and pharmaceutical supply chain
Presentation for ECSLA/ Cold chain association October 2012, Madrid

Agenda
• The Cool chain problem for global supply chains
• A potential solution
• Experiences and results with Tyvek® Air cargo covers
Protection in catering
Protection of from heat or cold with pallet cover
• Looking ahead
How can an improved product meet requirements in the food supply chain

Coolchain Problem: supply chains impacted by temperature
Solar Radiation
Solar radiation on food held in direct sunlight increases the temperature above the ambient temperature. The amount of increase in temperature depends on the intensity of the radiation, shape and duration of exposure
Intensity of solar radiation depends upon latitude, altitude, season, time of day, and degree of cloud cover.
• high temperature is detrimental to food quality and increases wastage
• in tropical climates considerable quantities food deteriorate at a rapid rate

Today most
products are in

uncovered or shrink
wrapped
Temperatures of shrink wrapped paletts can reach above ambiant
temperature due to greenhouse effect. Tyvek® can mitigate this effect

Summary: Cold chamber Test at 5 deg C
•Ambient Temperature exposure of the pallets was 5°C, in a cold chamber
•Starting product temperature was about 25°C
•Improved DuPont™ Tyvek cover kept the temperature over 15°C for about 33
hours
•Time gain between the Improved Tyvek® cover for pharmaceuticals and classic
white Tyvek® cargo cover was about 50% or 11 hours (maintain above 15 °C)
•There can be significant differences between bottom of pallet and top
•Products taken to a fridge take many hours to reach 5 deg C !!!!!

Cold temperature performance: How to avoid freezing?
• To quantify the level of protection by
an Air cargo cover when sensitive perishable
Products transitions from a warm (25 C) to a
cold environment (-20 C)
• The elapsed time was measured before a
product reaches freezing point
25
Air Cargo Covers offer protection against cold 25 deg C to - 20 Deg C
Test Results - Tyvek® cover vs. No cover at (– 20) Deg C
Test Conditions:
-Two pallets with simulated loads consisting of water filled plastic eggs were conditioned for 24 h @ 25degC
-Both pallets were then immediately moved to a controlled environmental chamber at -20 degrees C.
