REPULPABLE, RECYCLABLE, COMPOSTABLE AND BIODEGRADABLE REINFORCEMENT ELEMENTS AND PAPER REINFORCED TAPES, AND CONTAINERS INCLUDING THE SAME

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.

Composite adhesive layer for a laminate structure

An article includes a substrate including a bonding surface area, a first adhesive disposed on the bonding surface area in a first discrete pattern, the first adhesive comprising a hot melt adhesive, and a second adhesive disposed on the bonding surface area in a second discrete pattern that is complementary to the first discrete pattern, wherein the first discrete pattern comprises about 1% to about 25% of the bonding surface area and the second discrete pattern comprises a balance of the bonding surface area.

MODIFIED RESINS AND USES THEREOF

Modified thermoplastic hydrocarbon thermoplastic resins are provided, as well as methods of their manufacture and uses thereof in rubber compositions. The modified thermoplastic resins are modified by decreasing the relative quantity of the dimer, trimer, tetramer, and pentamer oligomers as compared to the corresponding unmodified thermoplastic resin polymers, resulting in a product that exhibits a greater shift in the glass transition temperature of the elastomer(s) used in tire formulations. This translates to better viscoelastic predictors of tire tread performance, such as wet grip and rolling resistance. The modified thermoplastic resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the modified thermoplastic resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, snow performance, and wet braking performance.
