摘要： This decorative film is to be bonded to a resin molded body by means of thermoforming, and comprises a sealing layer (I) that contains a polypropylene resin (A) and a layer (II) that contains a polypropylene resin (B). The polypropylene resin (A) satisfies the requirement (a1), while the polypropylene resin (B) satisfies the requirement (b1). (a1) The melt flow rate (MFR (A)) (at 230° C. under a load of 2.16 kg) is more than 0.5 g/10 minutes. (b1) The melt flow rate (MFR (B)) (at 230° C. under a load of 2.16 kg) and the MFR (A) satisfy relational expression (b-1). MFR (B)

摘要： Disclosed herein is a polypropylene-based decorative film to be used for three-dimensional decorative thermoforming, which film is capable of achieving both of sufficient adhesive strength and product appearance and is easy to recycle. A decorative film of the present disclosure contains a layer (II) including a resin composition (B) containing a polypropylene-based resin (B), in which the resin composition (B) satisfies the following requirements (b1) and (b2):(b1) the melt flow rate (MFR)(B) (230° C., a load of 2.16 kg) is 40 g/10 minutes or less, and (b2) the strain hardening degree λ is 1.1 or more
