Tapes with Easy Mount Adhesive L1815, L1820 L1715, L1720 L1515, L1520 L1015, L1020 L1315, L1320 L1915, L1915S, L1920S, L1920 L1215, L1220 L1115, L1120 Technical Data March, 2017 Product Description 3M™ Cushion-Mount™ Plus Plate Mounting Tapes with Easy Mount Adhesive are designed for mounting flexographic print plates to cylinders or sleeves. This family of foam mounting tapes provides excellent print quality for process, combination, and solid printing. This product is designed to provide easy and clean removal of printing plates across a wide range on printing applications with excellent resistance to plate lifting. Features • Offers a complete range of foam densities providing excellent print quality from process to combination to solid printing.

  • Consistent caliper control allows the printer to use multiple foam densities on a print job to optimize print quality.
  • Use the 3M proprietary Easy Mount liner, creating micro-channels in both adhesive surfaces. The crosshatched pattern creates a continuous and permanent network of micro-channels in the adhesive, allowing air to escape from between the tape and cylinder/sleeve and between the tape and plate.
  • The adhesive on the linered side (plate side) of the tape is designed for mounting of photopolymer plates, excellent holding power on-press and clean plate removal when demounting.
  • The adhesive on the non-linered side (cylinder side) of the tape is designed for mounting to flexographic printing cylinders or sleeves, providing easy application at mounting and clean removability when demounting.
