Dual pressure sensitive adhesive sheet for instore signage

A tandem system of metering and donor rolls is used to apply two different adhesives to a fully adhesive backed multilayer sheet to produce variably distributed adhesives and properties. Each of the two adhesives is unique and is cured differently to create a layer of adhesive that has differing adhesive properties on the sheet. A clear adhesive is applied to a top portion of cards before they are cut from the sheet and has a higher tackiness than the adhesive applied to the rest of the cards on the sheet in order to reduce glue buildup on blades cutting the cards from the sheet.
