- 0.020 inch (0.51 mm) double coated medium density purple foam tape
- Securely bonds flexographic plate to sleeve or cylinder to prevent plate edge lift during printing
- Up to 78% easier to remove plate from tape*; up to 54% easier to remove tape from sleeve**
- Designed to be easily removed from ink-contaminated print plates
- Ideal for printing combinations of solids and process with halftone dots
- Virtually no air bubbles under the plate or tape due to the air release feature designed into the tape
- Grooves in the adhesive are created by a crosshatch pattern from the release liner
- Purple foam color indicates the medium density foam
- Plate demounts from the tape without adhesive residue to help reduce plate damage and increase efficiency
- Allows clean, one-piece tape removal without scoring or damaging the print sleeve
3M™ Cushion-Mount™ Pro Plate Mounting Tape with Comply™ Adhesive System 21520 Purple is designed for mounting flexographic photopolymer print plates to print sleeves or steel cylinders. It features the Comply™ Adhesive System, which has the air release feature designed into the tape. This plate-mounting sticky-back purple foam tape provides high-quality medium print.
The crosshatch pattern in the adhesive layers releases air so there are virtually no bubbles that require remounting
Optimal, Consistent, Productive Flexographic Plate Mounting
3M™ Cushion-Mount™ Pro Plate Mounting Tape with Comply™ Adhesive System 21520 Purple is a purple foam tape that provides high quality medium combination print. It has the air release feature designed into the tape to allow for bubble-free mounting and predictable, repeatable print results. This flexographic plate mounting tape is tolerant of ink contaminants and has a dependable adhesive that resists lifting on press yet removes cleanly from the print plate and the cylinder or sleeve. It is up to 78% easier to remove the flexographic photopolymer plate from this tape* and up to 54% easier to remove the tape from a sleeve** to help keep print operations productive.

3M flexographic plate mounting tapes are highly engineered to provide very tight caliper tolerance to allow printers to use tape from different manufacturing lots and keep tight print registration. The compressible foam will withstand long and high-speed print runs.
This cushion tape is manufactured for 20 mil applications. It is constructed with differential acrylate adhesives. The adhesive on the linered (plate) side of the tape is designed for mounting photopolymer plates. The adhesive on the non-linered (sleeve / cylinder) side is designed for mounting to flexographic printing cylinders or sleeves, providing easy application at mounting and clean removal when demounting.
On Easy with Reduced Air Entrapment
The 3M™ Comply™ Adhesive System features a crosshatch pattern of unique micro-channels that allow air to escape more easily than from mounting tapes using a pebbled or flat adhesive surface. Air bubbles disappear from between the tape and plate, and between the tape and sleeve or cylinder for virtually bubble-free mounting. Setup is faster with smoother surfaces for cleaner print quality and higher productivity. The adhesive maintains tight contact with reduced edge lifting.
Where Science Meets Craft
Printers are passionate about every job looking the best it can. For decades, 3M products have been there helping to improve the quality of the work that goes out and the efficiency of how it gets done.
