We use a laminate pouch with an Al barrier layer and a Mylar (PET) coating on the outside. In time the seawater corrodes away the Al along the edges of the pouch ultimately causing the pouch to fail. We have found Kapton tape placed on the edges helps prevent the pouch from failing but I was wondering if you had information as to the best type Kapton to use to adhere to Mylar in a seawater environmen that would hold up the longest. What are your recomendations? Thankyou Art We have an application where we need to store a Li battery under seawater.

Customers are not sure whether “1-mil” (25µm) thick polyimide tape refers to the polyimide film thickness or the total thickness, since ultimately polyimide tape is made up of both the polyimide film layer plus the silicone adhesive layer (read more about why we believe in silicone-based tapes here).
