Introduction of BGT-01 Internal Bond Tester
BGT-01 Internal Bond Tester is used to measure the energy required to rapidly delaminate a test piece of paper or board. Rupture of the test piece in the “Z” or thickness direction is initiated by a pendulum having a defined mass, moving at a defined velocity. The test is suitable for both single- and multi-ply papers and boards, including coated sheets and those that are laminated with synthetic polymer films. It is particularly suitable for papers and boards that may be subjected to z-direction rapid impacts, impulses or shock loads during printing or conversion.
BGT-01 Internal bond Tester has wide application in single and multi-layer paper and board, including coated paper and those with covered with synthetic polymer, board like case board, white board, grey board, ivory board etc.
Why testing internal bond strength?
Printing, converting and many product applications subject paper and paperboard to impulses, impacts and shock loads into or out of the plane of the sheet. These can cause structural failures such as surface picks, blistering or delaminations within the interior of the sheet.
The common denominators of these failures are
- the high velocity of the impact loads
- thshort time period during which the material is stressed, frequently one to a few hundred milliseconds
- the planar nature of the resultant sheet failure.
Principle
A square test piece is adhered to a flat metal anvil by means of double-sided adhesive tape. An “L”-shaped aluminium platen with the same surface area as the test piece is then adhered to the upper surface of the test piece, again, using double-sided adhesive tape. The assembly is secured in position and a pendulum allowed to impact the upper inside surface of the platen, causing it to rotate about its outside corner, splitting the test piece in the “Z” or thickness direction.
The energy absorbed in rupturing the test piece is calculated.

FAQs
What is internal bond strength?
Internal bond strength is the average potential energy, expressed as J/m 2 of surface, required to delaminate a test piece under the conditions of the test. The result is the difference of the potential energy before and the remaining energy after delaminating the test piece.
