The clean release magnet includes a pressure sensitive carrier layer having a permanent adhesive applied to a first face and a clean release adhesive applied to a second face. A magnet layer is removably affixed to the pressure sensitive carrier layer with the clean release adhesive, and a filmic face layer, having printing thereon, is attached to the magnet layer with an adhesive. The method of manufacturing enables manual or automatic application of clean release magnets onto products. With this arrangement, the magnet layer is non-tacky when removed from the pressure sensitive carrier layer, the original product label is visible upon removal of the clean release magnet and the product contents remain free from contamination from the clean release magnet. ## Claims ### Claim 1 A method of manufacturing a clean release magnet, said method comprising the steps of: printing information on a label layer having adhesive on at least one surface, thereby denoting a first layer; affixing a pressure sensitive carrier layer, having a clean release adhesive on a first surface and an adhesive on a second surface, to a magnet layer, to thereby denote a second layer; and affixing said first layer to said second layer, adjacent said magnet layer, to thereby denote a third layer, and simultaneously cutting said third layer to a predetermined depth, wherein said magnet layer is one of non-tacky and slightly-tacky when removed from said pressure sensitive carrier layer, and a surface of said magnet layer is exposed when removed from said pressure sensitive carrier layer such that when said exposed surface is magnetically attached to a metal surface, said exposed surface directly contacts the metal surface. ### Claim 2 (depends on 1) A method according to claim 1, wherein said adhesive on said second surface is one of a permanent adhesive and a clean release adhesive. ### Claim 3 (depends on 1) A method according to claim 1, wherein said label layer is self-adhering. ### Claim 4 (depends on 1) A method according to claim 1, wherein said label layer is at least one of plain paper, embossed or glossy paper, PVC (Polyvinyl Chloride), PET (Polyethylene Terephlatate) and Tyvek. ### Claim 5 (depends on 1) A method according to claim 1, wherein said magnet layer is one of flexible and rigid. ### Claim 6 (depends on 1) A method according to claim 1, wherein said pressure sensitive carrier layer is one of clear, opaque and having printing thereon. ### Claim 7 (depends on 1) A method according to claim 1, wherein at least one section of said pressure sensitive carrier layer is at least one of clear, opaque and has printing thereon. ### Claim 8 (depends on 1) A method according to claim 1, wherein said pressure sensitive carrier layer has a releasable backing layer affixed thereto. ### Claim 9 (depends on 8) A method according to claim 8, wherein said predetermined depth is defined by a distance from a top of said clean release magnet to a bottom of said clean release magnet, excluding a thickness of said backing layer. ### Claim 10 (depends on 1) A method according to claim 1, wherein said cutting is performed by die-cutting said third layer. ### Claim 11 (depends on 1) A method according to claim 1, wherein said cutting step separates said third layer into a usable product matrix and a waste product matrix, said method further comprising the step of discarding simultaneously said waste product matrix. ### Claim 12 (depends on 1) A method according to claim 1, further comprising the step of automatically applying said clean release magnet to a product. ### Claim 13 (depends on 12) A method according to claim 12, wherein said product is a postcard mailer. ### Claim 14 (depends on 1) A method according to claim 1, wherein said steps of printing, affixing said pressure sensitive carrier layer, affixing said first layer and cutting are automatically performed by a machine. ### Claim 15 A method of manufacturing a clean release magnet, said method comprising the steps of: providing a label layer having adhesive on at least one surface, thereby denoting a first layer; affixing a pressure sensitive carrier layer, having a clean release adhesive on a first surface and an adhesive on a second surface, to a magnet layer, to thereby denote a second layer; and affixing said first layer to said second layer, adjacent said magnet layer, to thereby denote a third layer, and simultaneously cutting said third layer to a predetermined depth, wherein said magnet layer is one of non-tacky and slightly-tacky when removed from said pressure sensitive carrier layer, and a surface of said magnet layer is exposed when removed from said pressure sensitive carrier layer such that when said exposed surface is magnetically attached to a metal surface, said exposed surface directly contacts the metal surface. ### Claim 16 (depends on 15) A method according to claim 15, wherein said adhesive on said second surface is one of a permanent adhesive and a clean release adhesive. ### Claim 17 (depends on 15) A method according to claim 15, further comprising the step of automatically applying said clean release magnet to a product.
