摘要： Disclosed is a cover tape which comprises at least a base layer (A), an intermediate layer (B), a peeling layer (C), the primary component of which is a thermoplastic resin, and a heat seal layer (D), the primary component of which is a thermoplastic resin that can be heat sealed to a carrier tape. The tensile storage modulus (c) of the thermoplastic resin that constitutes the peeling layer (C) is within the range of 1×106 Pa to 1×108 Pa. The tensile storage modulus (d) of the thermoplastic resin that constitutes the heat seal layer (D) is within the range of 1×108 Pa to 1×1010 Pa. The ratio of (c) and (d) satisfies 1×104≧(d)/(c)≧1×10. This kind of cover tape has the appropriate peel strength and sufficiently low fluctuation in peel strength when heat sealed to a thermoplastic resin carrier tape. Therefore, the tape will not tear even under shock caused by high-speed peeling, and sticking of electronic parts does not occur even when set aside for a long period of time of 24 to 72 hours in a high-temperature environment of 60 to 80° C.

摘要： Disclosed is a cover film, which includes at least a base layer, an intermediate layer, a releasing layer and a heat seal layer that can be heat-sealed to a carrier tape, and wherein the heat seal layer contains, as a main component, a styrene-acrylic copolymer that has a mass average molecular weight of 5000 to 20000. This cover film is suppressed in variation in release strength when separated from the carrier tape, and is capable of reducing problems in the mounting process of electronic components such as rupture of the cover film during the separation.

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) includes a resin composition which includes (a) a styrene-based resin composition and (b) an ethylene-α-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) includes 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： Disclosed is a cover film which is used in combination with a carrier tape and comprises at least a base layer, an intermediate layer, a releasing layer and a heat seal layer that is capable of being heat sealed to the carrier tape. The intermediate layer contains, as a main component, a linear low density polyethylene that is polymerized using a metallocene catalyst and has a tensile modulus of 200 MPa or less. The releasing layer contains a conductive material and also contains, as a main component, a hydrogenated resin of an aromatic vinyl-conjugated diene copolymer having an aromatic vinyl group content of 15-35% by mass. This cover film is small in variation in peel strength when the cover film is released, and is thus capable of suppressing troubles during the releasing in a mounting process.
