    • PROBLEM TO BE SOLVED: To provide a base film for producing a protective film which does not entrain air bubbles when produced as a rolled object, which can be quickly and easily pulled out from the rolled object and which does not entrain the air bubbles when adhered onto an adherend, an optical component in particular. SOLUTION: The base film is a laminated film which has at least two layers each comprising a polyolefin resin and these two layers each constitute an outermost layer of a side where an adhesive agent is laminated and an outermost layer of a side where the adhesive agent is not laminated. In the base film, average roughness (Ra) of a surface of the side where the adhesive agent is laminated is 0.25 μm or less and average roughness (Ra) of a surface of the side where the adhesive agent is not laminated is 0.30 μm or more.

    • PROBLEM TO BE SOLVED: To provide a sheet for coverlay film thermocompression bonding, to which unevenness trackability and mold releasability are imparted by forming a low-energy surface on at least one surface of a polypropylene-made base and which is free of contamination.
      SOLUTION: The sheet for coverlay film thermocompression bonding has a fluororesin-containing coating formed on at least one surface of the polypropylene-made base with a thickness of 0.01 to 5.0 μm, and fluororesin constituting the fluororesin-containing coating includes an urethane bonding part and an alkylene fluoride unit represented by formula 1. In formula 1, where F is fluorine and X is fluorine or chlorine.

    • PROBLEM TO BE SOLVED: To provide a film for packaging, capable of being torn off along an unsealing tape in a linear state and steadily, even if the unsealing tape is pulled in the diagonal direction, with respect to a packaging biaxially oriented film, such that unsealing tapes are laminated in the width direction of the film. SOLUTION: The film for packaging is of a biaxially oriented polypropylene resin, on which the unsealing tapes K are bonded for use in the direction parallel to the width direction of the film. The tensile elongation of the film in the longitudinal direction is 170% or lower, while the unsealing tapes K are bonded, for configuration, in the direction of the width of this biaxially oriented laminated polypropylene resin film, thus to be made into a packaging film for use.
