See full text

A paint film-protecting sheet (1) that effectively prevents adhesive transfer to the paint film is provided. The paint film-protecting sheet (1) includes a pressure-sensitive adhesive (PSA) layer (20), which is comprised of a non-crosslinking PSA, disposed on a polyolefin-based resin film serving as a supporting substrate (10). At least a surface portion (12) of the supporting substrate which adjoins the PSA layer is formed of a resin material that satisfies both of the following conditions: (1) it contains W wt % of a LLDPE having a density d of 0.925 g/cm3 or less, wherein W is greater than or equal to 20; and (2) it has a LLDPE content index α of 400 or more, the LLDPE content index α being defined as (0.935−d)×W×1000.
