Tyvek-brand desiccant bags are tear-proof and dust-free and meet FDA specifications for contact with food and drugs. They are used to absorb moisture when shipping food, pharmaceuticals, and electronic components.

Cartridge and capsule desiccants are FDA-approved for use in food and pharmaceutical applications. The silica gel is packed in a hard capsule or cartridge to save space when used in pharmaceutical bottles. Cartridges and capsules are best suited for use at temperatures below 100°F, but can be used at up to 302°F.
