Inter-Ply Bond Measurement Standards in Recycled Paperboard Production
Inter-ply bond standards mandate TAPPI T 541 or ISO 16260 testing under strict ISO 187 conditioning to prevent converting delamination on recycled paperboard.
3m 410b Tape
Adhesive Carrier
Double-coated paper tape with a firm rubber adhesive provides immediate high adhesion to a variety of paperboards and rubber plates. Known for its quick stick, 3m 410b tape facilitates rapid splicing and secure plate positioning in commercial flexographic printing environments. The heavy paper carrier ensures easy handling and straight tearing.
This paper backing also absorbs minor vibrations.
Shear Strength
Resistance to dynamic shear forces ensures that the mounting tape does not shift during high-speed rotation of the printing cylinder. High adhesive coat weight prevents slippage, especially when plates undergo continuous friction against the paperboard substrate. Flexographic printers rely on this stability to preserve print registration.
Standard shear resistance tests confirm that the bond withstands prolonged pressure without adhesive transfer.
Process Application
Practical execution of splicing and plate mounting requires clean removal after the print run is complete. While the tape holds firmly during operation, it must release from steel rollers and photopolymer plates without leaving adhesive residue or tearing the plate. The tape achieves this through a balanced formulation that remains stable under temperature fluctuations on the shop floor.
Safe removal protects expensive print plates from physical distortion and tearing. Proper tape selection thus avoids costly downtime spent cleaning residue off rollers, meaning that this tape represents a trade-off between permanent holding power during press runs and temporary removal during clean-up.
