High clarity, tear resistant, static dissipative cover tapes for two-piece surface mount device packaging tapes are described comprising of backing film, e.g. a polyester film, one side of which is coated with a thin layer of heat-sealable adhesive, e.g. an adhesive comprising a styrenic block elastomer, and the other side of which is coated with an organic antistatic agent. The cover tapes of this invention can be used with carrier tapes made from a variety of materials, e.g. polystyrene, polyvinyl chloride, etc., and demonstrate a consistent peel force of between about 10 and about 120 grams. |
