A biodegradable pressure-sensitive adhesive which can be readily coated indirectly onto biodegradable carriers, which comprises

at least 60 wt % of at least one polyurethane, and
at least one sulfonated carboxylic ester; and a method for producing a biodegradable adhesive tape, which comprises providing a pressure-sensitive adhesive of the invention as a dispersion in at least one organic solvent; coating this dispersion onto a release liner; removing the organic solvent; and transferring the pressure-sensitive adhesive onto a biodegradable carrier.

Adhesive compositions and patches, and associated systems, kits, and methods, are generally described. Certain of the adhesive compositions and patches can be used to treat tissues (e.g., in hemostatic or other tissue treatment applications), according to certain embodiments.

The invention provides a highly-tensile kraft paper adhesive tape and a manufacturing process thereof. The adhesive tape includes a kraft paper layer, a plurality of yarn layers, a kraft paper layer and glue layers, which are fixedly connected in sequence; the specific number of layers of the plurality of yarn layers can be multi-layered according to actual situations, and the two adjacent yarn layers, and each kraft paper layer and the corresponding yarn layer, are fixedly connected by adhesion layers. Yarns in the yarn layers are classified into warp yarns and weft yarns, which are distributed crosswise. The tensile strength of the adhesive tape can be effectively improved by providing the two kraft paper layers to form a matrix of the adhesive tape. A plurality of yarn layers are provided between the two kraft paper layers to improve the structural stability of the moisture-permeable and water-proof adhesive tape.
