Quick Picks from TempPack: Sideways Shippers and Temp Excursions

From corrugated cold chain considerations to the surprising effects of thermal shipper orientation, TempPack speakers offer important real-world tips.

Thermal shippers that are not symmetrical may experience temperature excursions when their orientation is changed.

Live from ISTA’s TempPack and TransPack in San Diego, here are some of the most interesting takeaways from Day 1:

Orientation and excursions

A major pharma company presented data on shipment monitoring and highlighted an important topic: thermal shippers that are not symmetrical may experience temperature excursions when their orientation is changed. In their study, a passive shipper—which stays in the 2 to 8°C range for 56 hours when oriented properly—only had a 24-hour range when the package was oriented sideways.

We can surmise that packages aren’t always kept upright during the trip. But they had orientation data to back it up: they found that the packages were oriented on their sides for 27% of the trip in U.S. trials and 50% of the time in shipments to India.

Legacy infrastructure

Legacy infrastructure doesn’t always gel with innovative packaging: 3PLs certainly have the movement of corrugated down to a science, but new packaging designs maybe too slippery for existing conveyors to pick up and may end up waiting at the edge until someone sees them. The packages may also be at risk of not staying firmly on the mode of transport, effectively turning them into missiles flying at the other packages in some cases.

Thermocouple placement

AeroSafe Global’s AJ Krokenberger talked about how payload contents are monitored, and how the method used can have a drastic effect on the recorded performance of a shipper.

In one study, the average gradient within the shipper was 0.8°C. It may not seem significant, but in a six-degree range from 2 to 8°C, that’s 13%! The moral of the story is that thermocouple and data logger placement during the DQ, OQ and PQ are important considerations, and choosing wisely can boost the confidence and reliability of a temperature-controlled shipping system.

Logistics issue with greener options

Carriers and 3PL employees are used to treating EPS as temperature-controlled and treating corrugated packaging as room-temperature shipments. One company in Denmark that was exploring greener cold chain options—treated corrugated for fish delivery—noted that cold chain corrugated boxes may not be treated as such by handlers because they’re not used to associating “corrugated” with “cold.”

Alexander Bardenstein, Product Manager at the Danish Technological Institute, highlighted bio-based biodegradable packaging. He also cautioned that companies making the switch from EPS containers, it’s important to look at what labeling or training will be needed on the part of handlers if the shipper doesn’t have the conventional “cold chain” appearance.

Amazon’s standards

Amazon has ISTA standards in the works for e-commerce fulfillment.

  • Project 6-AMAZON.COM-SIOC: For items that “ship in own container.”

  • Project 6-AMAZON.COM-Over Boxing: For individual retail packaged-product weighing 70 pounds or less being placed into a master shipping container (over box) either by itself with the addition of dunnage (air pillows, etc.) or with multiple individual retail packaged-products with dunnage.
