Our application requires a hermetically sealed, heat conducting pouch for a chemical heating reaction to conduct heat to a surrounding water environment. The byproducts of the heating reaction are hazardous and must be kept separate from the water environment. We have been attempting to make hermetically sealed aluminum foil pouches, and sealing aluminum to various polymers to no avail. The aluminum foil pouches leak regardless of the bonding method. We have attempted tapes, adhesives, epoxies, failed heat seals, etc.
Can aluminum foil be welded to itself, either heat welded or ultrasonically welded?
Also, are there any solutions available to seal aluminum foil to polymer films such as polyethylene, PET, or polypropylene?
