摘要： A cover film including, at least, (A) a substrate layer, (B) an intermediate layer, (C) a release layer and (D) a heat seal layer is provided. The release layer (C) comprises a resin composition which comprises (a) a styrene-based resin composition and (b) an ethylene-±-olefin random copolymer, with the content of the copolymer (b) in the release layer being 20 to 50 mass%, and which has a Vicat softening temperature of 55 to 80 °C, while the heat seal layer (D) comprises an acrylic resin having a glass transition temperature of 55 to 80 °C. By the cover film, a carrier tape of polystyrene or the like can be so heat-sealed even in a short time as to achieve sufficient peel strength. Further, the resulting heat-sealed carrier tape exhibits little variation in peel strength, so that when peeling, few components fly out of the carrier tape.

摘要： To provide a cover tape capable of sufficiently suppressing corrosion of metal portions of electronic components even when the electronic components are stored in a high temperature high humidity environment for a long period of time, and a carrier tape system for packaging electronic components, whereby when the cover tape is peeled, a proper peeling strength can be constantly obtained. A cover tape comprising at least a substrate layer and a heat sealing layer, wherein (1) an antistatic layer containing an antistatic agent and an anticorrosive agent, is formed on the heat sealing layer, or (2) the heat sealing layer side has an average surface roughness (Ra) of from 0.3 to 1.0 µm, and has an antistatic agent applied thereon to form an antistatic layer.
