Why Test Internal Bond Strength?
The Bonding Strength Testing Machine is essential for evaluating the internal bond strength of paper and paperboard. Products subjected to printing, converting, and various applications often face impulses and shock loads that can lead to structural failures such as surface picks, blistering, or delaminations. By measuring internal bond strength, manufacturers can prevent these issues and ensure the structural integrity of their materials.
Testing Principle
The test piece is adhered to a flat metal anvil using double-sided adhesive tape. An L-shaped aluminum platen is then fixed to the test piece's upper surface. A pendulum impacts the platen, causing it to rotate and split the test piece in the Z-direction. The energy absorbed during this process is calculated to determine the internal bond strength.
