Abstract
The paper reinforced tapes and reinforcement elements of this invention have improved repulpability, recyclability, compostability and biodegradability. Further, these reinforcement elements and paper reinforced tapes, despite being predominately paper, unexpectedly provide excellent container reinforcement properties and further can be used as opening tapes, closing tapes, tear tapes and carrying handles.
