Adhesive compositions are described which include one or more gelling agents in combination with one or more non-gelling disintegrants. The adhesive compositions exhibit relatively high fluid handling capacities and static absorption properties, thus enabling their use in a wide range of medical applications. Various adhesive articles such as dressings and related methods of use are also described which utilize the adhesive compositions. In preferred embodiments the adhesive component is an acrylic adhesive, the gelling agent is selected from the group consisting of (i) carboxymethyl cellulose, (ii) superabsorbent polymer, and (iii) combinations of (i) and (ii), and the non-gelling disintegrant is selected from the group consisting of (i) fully pregelatinized potato starch, (ii) microcrystalline celluloseand (iii) combinations of any of (i)-(ii).

A highly homogeneous starch-based glue composition is obtained by enzymatic modification of the starch with a branching enzyme which is supplied in an enzymatically modified starch with high long-term stability. The starch has a viscosity stability index SI of less than or equal to 1.3, calculated by the quotient of viscosity after 14 days and by viscosity after 2 hours after preparation of the starch. The starch is suitable for liquid storage, which is stable in the long-term, of a ready-to-use paste with a high bonding strength.

A water activated tape and method of producing is provided, the tape comprising a repulpable material, a water-soluble material affixed to the repulpable material, and a water activated adhesive layer affixed to the water-soluble material.

Repulpable water-activated tapes, in particular reinforced laminated, water-activated paper tapes and methods of making the same are disclosed. The repulpable water-activated tape includes an outermost paper layer having a top surface and a bottom surface, a reinforcement adjacent to the bottom surface of the outermost paper layer, an innermost paper layer having a top surface and a bottom surface, the top surface of the innermost paper later adjacent to the reinforcement, at least a portion of a starch-based laminating adhesive disposed about each of the outermost paper layer, reinforcement, and innermost paper layer, and a water-activated adhesive adjacent to the bottom surface of the innermost paper layer. A repulpable starch-based laminating adhesive and tape comprising same is also described.

The invention provides a method for preparing a binder precursor, the method comprising the steps of: i) mixing (A) fungi or glucan and (B) starch with an alkaline agent in the presence of an aqueous solvent system to form an alkaline composition; ii) mixing the alkaline composition with an acidic agent to form a mixture; and iii) drying the mixture and forming a powder therefrom, so as to form a powdered binder precursor.

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.
