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： 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： A winding state evaluation method of a tape film includes a step of determining the attenuation rate of ultrasonic wave for the tape film (2) by sending an ultrasonic wave to the tape film (2) in parallel with the direction of the axis of rotation of a core (1) and receiving its reflected wave or transmitted wave, and a step of evaluating the winding state of the tape film (2) from the distribution state of the attenuation rate in the tape film (2). The method can judge the winding state of the tape film objectively by presenting its numerical representation concretely without relying upon sensual evaluation.
