Precision measurement of backsheet films across five products revealed that seemingly trivial thickness differences — as small as 0.01mm — corresponded to breathability differences exceeding 30%. The finding redirected the client from pursuing premium topsheet upgrades to addressing backsheet specification first.

Engineering Story
Why Only CORIO
Backsheet is the most overlooked layer in diaper engineering. Consumers feel its effect but cannot articulate it — which is exactly why engineering data matters more than focus groups here.
