Abstract
This invention relates to a novel fastening method with multiple applications, and different stationery products derived therefrom. The method offers practical and economical solution to different problems and needs associated with many different fastening functions. This method is particularly useful and advantageous in the paper, cardboard and film products industries. The method eliminates the need to moisten coatings of adhesive, or the need to use removable release liners to protect the adhesive coatings on the articles that need to be fastened. The method further enables the creation of new products, to solve existing needs, as for instance, self sealing and self contained forms suitable for desktop and any other type of printers. In very broad terms, the method consists of applying layers of a fastener, such as a pressure sensitive adhesive (PSA) substance 202 and layers of a fastening inhibitor substance, such as a release substance 206 to the surfaces on planes 201 and 203 that need to be fastened, in such a manner that they can be in direct contact and remain unattached or be temporarily attached until a more permanent attachment is desired, which is usually achieved by p…
