Abstract
A business form having an integrated label in its top ply or other sheets advantageously includes a release sheet which is only partially covered with a release coating in order to provide a controlled release. The controlled release is provided by skiving lines which preferably remove a portion of the release coating within a border on the release sheet. The adhesive layer is thereby directly connected to both the label and the release sheet. The release coating is penetrated intermittently by the skiving lines to remove a portion of the release coating. Alternatively, a pattern of release coating of silicone or the like may be printed in a pattern so that the release coating is only intermittently provided in covering relationship over the release sheet. The provision of intermittent direct contact between the adhesive and the release sheet provides improved adhesion of the label to the liner without detracting from the functionality of the form or the label.
