Colorcon offer service "Desiccant DRICARD"

DRICARD® is a flat moisture-absorbing plate made of calcium chloride desiccant laminated between paper fibers and film layers, keeping packaged nutraceuticals, foods, and diagnostics protected from moisture damage much like conventional desiccant packets. Its slim profile fits small or narrow packaging spaces, or situations where it must not be mistaken for the end product, and it is offered in a range of standard sizes with custom sizing available. Regulatory compliance can differ by country and end use, so a Colorcon representative should be consulted; DRICARD® is a trademark of BPSI Holding LLC.
