Abstract
High transparency, low-haze, static dissipative cover tapes for two-piece surface mount device packaging tapes are described comprising a metallized backing film, e.g. a polyester film one side of which is coated with a thin layer of aluminum, and a heat-sealable adhesive, e.g. an adhesive comprising a styrenic block elastomer, a tackifier, a plasticizing agent, an antiblock agent, and a conductive material such as nickel flakes. The cover tapes of this invention can be used with carrier tapes made from either polystyrene or polyvinyl chloride, and demonstrate a consistent peel strength of between 30 and 80 grams.
