Packaging Strategies has reported extensively on innovations in caps and closures in recent months. Perhaps most astonishing — aside from the innovations themselves — is that each of them is uniquely different as far the materials utilized, the applications, and the specific benefits being touted.

Take, for instance, Blue Ocean Closures, which has introduced a cellulose fiber cap that it describes as “recyclable as paper.” Blue Ocean Closures has found a great partner in nutritional supplements producer Great Earth, which is using the fiber screw cap to reduce its plastic use by 2.6 tons a year.
