How to test an insulated shipping pouch in a packout

Do not assume pouch performance alone; compare complete packouts with temperature records on route.

Short answer

Test the pouch together with product, inner pack, coolant and outer carton. For the same load, starting conditions and route, use a logger near the product in trials with and without the pouch. Record sun exposure, waiting and delivery time. The result applies only to the tested combination.

Insulated-pouch performance depends on material, closure, coolant, load and external conditions. Do not assume the pouch has a fixed protection duration by itself.

Test the complete pack. Specify the inner product pack and coolant; use the same outer carton if required. Check closure, puncture or leak risk and protection against crushing during handling.

Run a comparison with the same product and starting temperature. Use the pouch in one pack and omit it in the other; place a logger near the product in both. Keep route, ambient conditions, sun exposure, waiting and delivery time the same, or record differences.

At arrival, inspect product readings and both logger traces. Report the pouch's contribution only for this pack and these conditions; do not generalize automatically to another product, route or season.

If the result is inadequate, adjust packaging layers, coolant or transport method according to product instructions and repeat the test.
