Abstract
A plate mounting tape with a self-adhesive composition on both sides of a polyolefin substrate, in particular PE foam film substrate having low variation in thickness and having a compressive stress value of 10-80, in particular 10-50 N/cm2 under 50% compressive deformation.
Claims7
A method for removable mounting of a flexographic printing plate to and from an impression cylinder, said method comprising:
- A) adhering a first face of a double-faced adhesive tape to said cylinder;
- B) adhering said printing plate to a second face of said double-faced adhesive tape;
- and thereafter
- C) removing both the printing plate and the cylinder from said double-faced adhesive tape;
- wherein the double-faced adhesive tape is a double-faced adhesive tape comprising a polyolefin foam substrate and a self-adhesive composition directly on both sides of the substrate without a reinforcement layer between the substrate and the self-adhesive composition on the substrate, the self-adhesive composition permitting subsequent separation from surfaces between which the tape is applied, the polyolefin foam being monoaxially stretched, having a thickness of 200 to 1000 μm with a variation of no greater than ± 12%, and having a compressive stress value of 10 to 80 N/cm2 under 50% compressive stress deformation.
