摘要:
A hot melt adhesive composition that includes a propylene-alpha-olefm polymer including at least 50 mole % propylene and has a ratio of z average molecular weight (Mz) to number average molecular weight (Mn) (Mz/Mn) from greater than 20 and no greater than 50, a ratio of Mz to weight average molecular weight (Mw) (Mz/Mw) from greater than 2.5 to no greater than 6, a crystallinity of at least 5 %, and a viscosity of no greater than 2,500 centipoise at 190°C, and from 10 % by weight to no greater than 30 % by weight tackifying resin, the adhesive composition having a viscosity no greater than 10,000 centipoise at 149°C.
摘要:
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, dosing tapes and carrying handles.
