A reusable, liner-free attachment system is described herein. The attachment system is compatible with the surfaces of a variety of materials, regardless of composition or physical characteristics. The system contains an anchoring site and a detachable article that binds specifically to the anchoring site. When bound together, the system provides anisotropic resistance to applied forces. The system is highly resistant to shear stress, but is easily detached by applying a pull-off force. The article typically contains a part A coating on the side or portion of the article that attaches to the anchoring site. The system can be used with a variety of articles, such as hooks, carpet tiles, medical devices, such as blood pressure cuff; climbing equipment, such as gloves, shoes or handles.

1. An attachment system, comprising a liner-less part A coating strip and an anchoring site, wherein the part A coating strip is located on a first portion of an object, and the anchoring site is located on a second portion of the object,wherein the part A coating strip attaches to the anchoring sit
1. An attachment system, comprising a liner-less part A coating strip and an anchoring site, wherein the part A coating strip is located on a first portion of an object, and the anchoring site is located on a second portion of the object,wherein the part A coating strip attaches to the anchoring site via electrically neutral attachment forces, wherein the part A coating strip resists shear stress when it is attached to the anchoring site, andwherein the part A coating strip has a 0° peel strength between 40,000 and 100,000 g/in, inclusive, as measured when the part A coating strip is placed on top of the anchoring site and the part A coating strip is pulled in a direction parallel with the plane of the part A coating strip, wherein the anchoring site is clamped to prevent its movement. 2. The attachment system of claim 1, wherein the anchoring site comprises an anchoring site coating or an anchoring site coating strip. 3. The attachment system of claim 2, wherein the anchoring site coating strip comprises polyvinyl chloride, and one or more plasticizers. 4. The attachment system of claim 1, wherein the part A coating strip is integrated into or affixed to the first portion of the object. 5. The attachment system of claim 1, wherein the object is a blood pressure cuff. 6. The attachment system of claim 1, wherein the part A coating strip is formed from a material selected from the group consisting of polyvinyl alcohols; polyvinyl acetates; polyvinylpyrrolidones; polyvinylpyrrolidone-vinyl acetate copolymers; polyacrylic acids; polyethylene glycols; poly(2-ethyl-2-oxazoline); polyacrylamide copolymers; ethylene vinyl acetates; natural and reclaimed rubbers; polyurethanes; non-carboxylated and carboxylated styrene-butadiene rubbers; polyacrylates based on the polymerization of monomers of methacrylates, methyl acrylate, ethyl acrylate, 2-chloroethyl vinyl ether, 2-ethylhexyl acrylate, hydroxyethyl methacrylate, butyl acrylate, or butyl methacrylate; polyamides; polyesters; polyolefins; chlorinated-polyolefins; polyolefins containing maleic anhydride; polystyrene acrylates; polystyrenes; polyvinyl esters; polyvinyl ketones; polydiene elastomers; polyiso butylenes; poly butadienes; polychloroprenes; poly styrene acrylics; carboxylated acrylic; styrene and/or butadiene polymers; cellulose derivatives; ureas; gelatins; alginates; agars; gum arabics; and combinations thereof. 7. The attachment system of claim 1, wherein the part A coating strip comprises an acrylic polymer, and wherein the coating on the anchoring site comprises plasticized polyvinyl chloride. 8. The attachment system of claim 1, wherein the object is a strap. 9. A method for using an attachment system, wherein the attachment system comprises a liner-less part A coating strip and an anchoring site, wherein the part A coating strip is located on a first portion of an object, and the anchoring site is located on a second portion of the object, the method comprising:(i) applying the part A coating strip to the anchoring site, wherein the anchoring site is affixed to the object; and(ii) removing the part A coating strip from the anchoring site, wherein no transfer of coating from the part A coating strip to the anchoring site occurs;wherein the part A coating strip attaches to the anchoring site via electrically neutral attachment forces; wherein the part A coating strip resists shear stress when it is attached to the anchoring site;wherein the part A coating strip has a 0° peel strength between 40,000 and 100,000 g/in, inclusive, as measured when the part A coating strip is placed on top of the anchoring site and the part A coating strip is pulled in a direction parallel with the plane of the part A coating strip, wherein the anchoring site is clamped to prevent its movement. 10. The method of claim 9, wherein the anchoring site is permanently attached to the object via co-extrusion during manufacturing. 11. The method of claim 9, wherein the side of the anchoring site that is not in contact with the object comprises an anchoring site coating strip. 12. The method of claim 11, wherein the anchoring site coating strip comprises polyvinyl chloride and one or more plasticizers. 13. The method of claim 9, wherein the part A coating strip is integrated into or affixed to the first portion of the object. 14. The method of claim 9, further comprising (iii) repeating steps (i) and (ii) one or more times.
