  • 0.020 inch (0.51 mm) double coated medium density purple foam tape
  • Adhesive technology with low adhesion for easy demount or removal from cylinder/sleeves
  • Designed to be easily removed from ink contaminated print plates
  • Ideal for printing combinations of solids and process with halftone dots
  • L1520A securely bonds the flexographic photopolymer plate to the print sleeve or steel cylinder to prevent plate edge lifting during printing
  • Print plates mounted on L1520A will have no air bubbles under the plate or tape due to the air release feature designed into the tape
  • Purple foam color indicates the medium density foam
  • Grooves in the adhesive are created by a cross-hatch pattern from the release liner
  • Plate easily demounts from the double coated cushioned tape without adhesive residue
  • Tape also removes easily and cleanly from the sleeve or steel print cylinder
  • Flexographic printing, flexographic printers

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.

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.

Recommended Applications
  • Flexographic printing, flexographic printers
  • Mounting photopolymer plates to flexographic printing cylinders and sleeves
  • Used in combination, process and solid printing processes
  • 3M sticky back tapes are designed for wide-web presses to print film or paper for flexible packaging industry

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.
