When is the best time to fit thermal covers during the shipping process?

Covers should be fitted when the freight is at the correct temperature, and the covers themselves should also be at the same temperature.

Product Q&A

Q:What is the difference between temperature control and temperature protection?

Temperature control packaging uses insulating and phase change materials to hold temperature for a validated duration, while temperature protection (like thermal covers) only slows temperature exchange without holding specific limits.

Q:Do thermal covers work the same in cold weather?

They slow down temperature exchange in cold weather, often better than in hot conditions. Freight temperature takes longer to drop in cold weather than it does to rise.

Q:Are thermal covers easy to fit and remove?

Yes, preformed covers fit over pallets like a hat and seal in minutes. Rolls of silver-backed bubble may take up to 20 minutes for two people if not preformed.

Q:Will adding a second cover double the performance?

No, but it improves performance considerably by an estimated 40-60% depending on conditions. A third cover adds only around 5-15%.

Q:Will using gel packs or phase change materials help performance?

Potentially yes. Gel packs can be placed on top of the product or in pockets on reusable thermal blankets to provide an additional barrier against sunlight.
