- 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

- 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.
