Beschreibung
Zusammenfassung:	The purpose of the present invention is to provide a storage state in which a reactive compound layer can be stably maintained in a polymer film having a reactive compound layer on the surface. The film roll is obtained by winding together: a first polymer film having a reactive compound layer on the surface, and a second polymer film having a surface roughness (Ra) of 0.1 μm or more and a modulus of elasticity of 300 MPa or more and 10 GPa or less. The film bundle is obtained by laminating the first and second polymer films. Preferably, storing the film roll and the film bundle at a low temperature enables a thin layer of a reactive compound to be stably maintained.
