ABSTRACT:
A flexographic printing plate mounting sheet is provided which improves the printing accuracy by its high level of thickness accuracy and ease of installation in the correct position, which makes it possible to peel a flexographic printing plate off without damaging a foamed substrate, and which maintains appropriate cushioning properties. The foamed substrate of the flexographic printing plate mounting sheet has an adhesive layer on one side and a polyethylene terephthalate film on the other side. The polyethylene terephthalate film has on its remaining side an adhesive layer that is protected by release paper. The foamed substrate and the polyethylene terephthalate film are unitarily formed. The foamed substrate is made of urethane foam having a density of 0.3 to 0.6 g/cm3. The polyethylene terephthalate film is 12 to 50 μm in thickness.
