EPS Foam vs Soft Insulation

While there's definitely a winner and loser here when it comes to comparing temperatures for shipping perishables, hard foam has a few other variables.  Here's our 47 hour test (I got impatient and opened 'em up an hour early.)

These are 10x10x5 boxes packed with a 24 oz gel pack and 8 Treats each, plus the datalogger and a small amount (say, ¼ lb) of dry ice.

PT 1 (black line) is 1" thick Plymouth Foam SilverLiner.

PT 2 (blue line) is 1.5" thick ThermalShipping Renewliner. 

Yep, that's a 10 degree difference at the end of the test, and that's especially impressive because the SilverLiner is only 1" thick compared to 1.5" for the RenewLiner.  So why the heck would anyone use the Renewliner?  

 

One word:  Space.  We can only fit 8, maybe 9 Treats into the SilverLiner.  We can fit 12 Treats plus one or two other items with the RenewLiner.

We think the SilverLiner looks way cleaner than the Renew, but at the end of the day we're a shipping company, not a looking company.  If we can only fit 8 Treats into a SilverLiner box, that limits our profit per order. 

That wraps it.  What works for us may not work for you, but now you've got one more datapoint to make a good decision on what the best way to ship for your business is.
