Publication number: 20240042747Abstract: The invention features a reinforcement element including a continuous paper strip having a first side and a second side, a first adhesive composition disposed on at least one of the first side and second side. The invention further features a paper reinforced tape including a continuous paper strip, a continuous paper backing layer and a first adhesive composition disposed between the continuous paper strip and the continuous paper backing layer thereby adhering the continuous paper strip to the continuous paper backing layer. 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 and carrying handles.Type: ApplicationFiled: October 19, 2023Publication date: February 8, 2024Inventors: Michael J.
