摘要： The invention relates to a two-side self-adhesive tape whose sides have different adhesive forces and are provided with at least one adhesive layer. Said invention is characterised in that the glue of the less adhesive layer is based on ethylene vinyl acetate copolymer whose vinyl acetate part in the copolymer ranges from 25 to 92 mass %. in a preferred embodiment from 40 to 70 mass %, the adhesive substance can be possibly mixed to additives such as adhesive resins, softeners, antioxidants and fillers.

摘要： Disclosed is a double-sided pressure-sensitive adhesive tape having sides which differ in adhesive strength, and a method for its preparation. The double-sided pressure-sensitive adhesive tape comprises at least one adhesive layer comprising a pressure-sensitive adhesive based on a chemically crosslinked polyurethane. The double-sided pressure-sensitive adhesive tape is especially well-suited to adhere flexible storage media, such as CDs, CD-ROMs and DVDs, to curved, bent or creased surfaces. The double-sided pressure-sensitive is also especially well-suited for adhering customer cards and credit cards to paper.
