The present invention relates to an adhesive composition comprising, among others, (i) microfibrillated cellulose and (ii) a metal in oxidation state of II or greater. The present invention further relates to uses of such an adhesive composition and to products prepared with such an adhesive composition. Furthermore, the present invention relates to a process for making corrugated paperboards or cardboards, or solid paperboards or cardboards by using such an adhesive composition.

A method and a mineral wool product include a multiple of lamellae, such as a sandwich panel core. The product includes a plurality of lamellae cut from a mineral wool web, and bonded together by applying an adhesive on the surfaces of two adjacent lamellae to form a web-like product, wherein the adhesive comprises at least one hydrocolloid.

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.

A water based glue stick composition includes adhesive and nanocrystalline cellulose. The composition is contained in a glue stick that can be used for planar joining of substrates to one another. The substrates can include paper and/or cardboard such as printer paper, photo paper and cardboard paper.

The development of the Dissolvable Labels for Medvantage® Machine fulfills this need. The Dissolvable Labels for Medvantage® Machine, as its name implies, is a line of dissolvable labels for use on a specific brand of printer. The labels would be used in a wide variety of applications including healthcare, foodservice, sterile processing, and other similar applications. They would be made available in a wide variety of sizes including but not limited to 2½″ square, ⅞″ by 1⅝″, ⅞″ by 2¼″, and similar sizes. Also, in addition to various colors, the invention would be made in various finishes such as synthetic and matte. The invention is specifically designed for use in printers manufactured by MedVantage®, although they could be adapted for use with different manufacturers as well. The use of the Dissolvable Labels for Medvantage® Machine allows for the production of labels that can be removed at a later time in a manner which is not only quick, easy, and effective, but ecologically and economically friendly as well.

A method of using a self-stick insulation. The method includes providing a piece of insulation product with an adhesive coating. The adhesive coating includes polystyrene-maleic anhydride (SMA) and/or polyacrylic acid (PAA); an alcohol amine; and at least one of a polyvinyl alcohol and a starch. The adhesive coating is then activated with liquid water. Once the adhesive coating is active, the insulation product is attached to a surface with the adhesive coating.
