Abstract
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.
