A water-based adhesive for the manufacture of laminated cellulosic boards includes monolayer graphene oxide as a glue enhancer. Laminated cellulosic boards may be obtained by providing cellulosic plies, applying a water-based adhesive, and contacting the surface of another cellulosic ply to the first cellulosic ply. A method for producing the water-based adhesive includes mixing starch, water and glue enhancer. The glue enhancer is a suspension of between 0.1 wt % and 0.001 wt % of monolayer graphene oxide in water.

Described herein are physically crosslinked, closed cell continuous multilayer foam structures that includes a foam layer comprising polypropylene, polyethylene, or a combination of polypropylene and polyethylene and a polyamide cap layer. The multilayer foam structure can be obtained by coextruding a multilayer structure comprising at least one foam composition layer and at least one cap composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.

A structural member including a lightweight core, one or more skins, and a crosslinking nanolayer interposed therebetween that results in significant mechanical strength in the structure. The core is a polymer of reduced density by way of included voids, such as an open or closed cell foam, honeycomb, or corrugated structure. The core polymer has a lower density and may have a higher softening or melting temperature than the polymer skin materials. The core may be discontinuous at the interface with the skin such that only a small percentage of the core surface is actually in contact with the skin compared to the overall area of the interface. The skin may be a thermoplastic layer that attaches to the core material. The skin may be a composite material including non-thermoplastic reinforcements. The crosslinking nanolayer is covalently bonded to the surface of the core material and provides molecular compatibility with the skin material.

The present invention deals with a multilayer structure comprising a first polyethylene layer as a first external layer. The first polyethylene layer is oriented in at least machine direction. The structure also comprises a second polyethylene layer as a second external layer. It further comprises a layer made of a copolymer of ethylene and vinyl alcohol (EVOH) between the first external layer and the second external layer and a tie layer on each side of the EVOH layer. Furthermore, the tie layers comprise one or more copolymers of ethylene.

A film structure includes a barrier layer, a first encapsulation layer, and a second encapsulation layer. The barrier layer is formed of a barrier material having a first side and a second side.
