(57) Abstract: A peelable protective film composition of the present invention comprises: Polypropylene 1 having a specific B content, MFR, Mw / Mn, and a parameter B value showing the randomness of the copolymerized monomer chain distribution. -Betylene random copolymer (A), ethylene and 3 to 10 carbon atoms Of α-olefin, and contains a specific MFR and ethylene-α-olefin copolymer (B) having a specific ethylene content in a specific ratio, and further contains a tackifier (C). Good. The peelable protective film of the present invention is a single-layer or multi-layer film, and at least one outermost layer of the film is composed of the composition as described above. [Effect] According to the above composition, the composition has excellent flexibility, scratch resistance, heat resistance and transparency, and also has appropriate initial adhesive strength and peeling property with respect to an adherend, and cold workability during adhesion. Also, a peelable protective film that is less likely to change over time when stored for a long period of time and that does not leave a bleed on the surface of an adherend even after peeling is obtained. |
