摘要:
The present invention provides a self-adhesive film which is a drawn polypropylene-based resin film comprising a laminated body containing an adhesive layer and a release layer which are provided on the surface of a base layer formed of a polypropylene-based resin, wherein an average surface roughness SRa of a surface of the above-described release layer is 0.200 μm or less, an average surface layer roughness SRa of a surface of the self-adhesive layer of the film is 0.030 μm or less, the contact area with the adherent, which is defined in the description, is 90% or more and 100% or less, and the film haze ranges from 1 to 40%. The self-adhesive film of the present invention is less likely to cause a blocking after the film is stored in a rolled state, and the processing suitability is excellent, and forming is less likely occur even when the film having been adhered to an adherend is processed at a high temperature, and further transparency is excellent.
