Wet Shrink Bands are easy to apply with no special machinery or heat required. As they dry, they shrink and apply a continuing pressure that holds the closure in place. Cellulose bands are tubular in shape and are kept wet in special shipping containers. They are applied wet and shrink as they dry in a form-fitting seal. They do not leave any residue and are biodegradable but tough and durable.
