（China）YYP 82 Internal Bond Strength Tester

1. Introduction

Interlayer bond strength refers to the board’s ability to resist interlayer separation and is a reflection of the paper’s internal bond ability, which is very important for processing multilayer paper and cardboard.

Low or unevenly distributed internal bonding values may cause problems for paper and cardboard when tiling in offset printing presses using adhesive inks;

High bonding strength will bring difficulty to processing and increase production cost.
