BANDAGE, HOT-MELT ADHESIVE FOR PRODUCING A BANDAGE,USE AND METHOD FOR THE PRODUCTION OF A HOT-MELT ADHESIVE
20230142331 · 2023-05-11 ·

The invention relates to the technical field of cohesive bandages. The invention relates to a bandage comprising a flat web material as a substrate, both main sides of the substrate being coated at least partially with a hot-melt adhesive. The invention also relates to a hot-melt adhesive for producing a bandage, to the use of a hot-melt adhesive for producing bandages, and to a method for producing a bandage. The hot-melt adhesive is based on a first polyolefin having—a proportion of 1-butene-derived monomer units; a proportion of ethylene-derived monomer units; and the hot-melt adhesive further comprises: at least one tackifier consisting of hydrocarbon resin and/or of hydrogenated hydrocarbon resin. The hot-melt adhesive can also contain a second polyolefin, preferably an amorphous polypropylene homo- or copolymer.

Adhesion Materials and Methods of Manufacture

The present invention consists in a new type of adhesion material and the method of production. This material is used in the medical area, or in areas where is necessary to connect a device to the skin. This connection occurred due to the polarity that exists in the two materials, more concrete through the electric bounds, in more specific the bound obtained is a hydrogen bound that is produced when the two materials are connected. The adhesion material comprises polyethylene glycol, citric acid, ascorbic acid, one or more sugars or sugar alcohol, glycerol as well as a lauric acid and/or oleic acid mixture with polypropylene grafted with maleic anhydride or Polyethylene grafted with maleic anhydride or poly (ethylene-alt-maleic anhydride) or polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene-graft-maleic anhydride or polyisoprene-graft-maleic anhydride or poly(methyl vinyl ether-alt-maleic anhydride) or poly(isobutylene-alt-maleic anhydride) or poly(maleic anhydride-alt-1-octadecene) or poly(ethylene glycol)methyl ether methacrylate solution.
