FDA Approval
The United States FDA has not approved molecular sieves for direct contact with consumable items yet, though in Europe they are used with pharmaceuticals. Lack of government approval for the use of molecular sieves in food and drug packaging has limited their more widespread use. Independent testing suggests that molecular sieves meet all government requirements but the industry has been unwilling to fund the expensive testing required for government approval.

Famous quotes containing the word approval:
“Hardly a man in the world has an opinion upon morals, politics or religion which he got otherwise than through his associations and sympathies. Broadly speaking, there are none but corn-pone opinions. And broadly speaking, Corn-Pone stands for Self- Approval. Self-approval is acquired mainly from the approval of other people. The result is Conformity.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
