Cold-set biobased laminating adhesive for paper or paperboard products, and packaging materials
InactiveUS20160194527A1Non-macromolecular adhesive additivesStarch derivtive adhesivesFiberPaper recycling
This specification relates to cold-set biobased adhesive compositions, comprising aqueous formulations of biopolymers, optionally with alkaline additives, optionally fortified with high-aspect-ratio inorganic and organic fillers, fibers and nanofibers, optionally with barrier-inducing additives. The adhesive may be used, for example, as a cold-set, preferably biobased, laminating adhesive. In particular, the laminating adhesive may be used to create liner and / or medium paperboard products for light-weight paperboard and corrugated boxboard materials that, in some examples, have enhanced strength and / or barrier properties as compared with similar weight paperboard products. These laminated paperboard and corrugated boxboard materials are used, for example, as light weight packaging materials that are compatible with paper recycling and composting operations. In the context of this abstract, the term “lamination” or “laminating” relates to the adhesion of two flat (rather than pre-corrugated) paper surfaces, i.e. the gluing together of two continuous sheets of paper or liner or medium paperboard.

Automobile part shipping system and method
Plies of paperboard are laminated to form a paperboard laminate having a front and a back. An automobile part is placed on the front of the paperboard laminate leaving exposed the front of the paperboard laminate. The automobile part and the exposed paperboard laminate are shrink-wrapped with plastic shrink-wrap material. For automobile window glass, some of the front side plies of the paperboard laminate have been cut out to form a cavity in the configuration of the glass product being packaged. The glass product is disposed in the cavity and a glass product conforming reinforcing block is placed against the backside of the paperboard laminate during the shrink-wrap operation. For automobile fenders, hoods, the paperboard laminate need not be cut out and the sides of the paperboard laminate are folded upwardly to form a carton bottom to which a lid is affixed for shipping.
