1. Introduction of BNP-01 Board Bursting Tester

BNP-01 Board Bursting Tester is used to measure the bursting strength of board submitted to increasing hydraulic pressure. It is applicable to all types of board (including corrugated and solid fiberboard) having bursting strengths within the range 350 kPa to 5 500 kPa, It is also applicable to papers or boards having bursting strengths as low as 250 kPa if the paper or board is to be used to prepare a material of higher bursting strength, such as corrugated board.

Our digital board Mullen burst strength tester is ideal for measuring the bursting strength of Paper Board. Designed specifically for paper board bursting strength testing, our equipment ensures accurate and reliable results.

2. Terms of Board Bursting Tester

Bursting strength: maximum pressure developed by the hydraulic system in forcing an elastic diaphragm through a circular area of the paper when the pressure is applied in the manner described in the method

Burst index: bursting strength of paper, in kilopascals, divided by the grammage of the paper determined in accordance with ISO 536

3. Why do you need a Board Bursting Tester?

The testing of bursting strength in board is a critical means of evaluating the material’s resistance to external pressure and impact. This test is significant in understanding the performance of board during packaging, transportation, and handling processes. Bursting strength refers to the ability of board to resist rupture under internal or external pressure. The results reflect the strength and durability of the board, assisting manufacturers in ensuring their products maintain integrity across diverse application scenarios, thereby reducing resource waste and transportation losses due to damage.

5. Test Principle of Board Bursting Tester

A test piece, placed over a circular elastic diaphragm, is rigidly clamped at the periphery but free to bulge with the diaphragm. Hydraulic fluid is pumped at a constant rate, bulging the diaphragm until the test piece ruptures. The bursting strength of the test piece is the maximum value of the applied hydraulic pressure.

9. FAQs of Board Bursting Tester

What is Paper and Paperboard Bursting Strength?

Bursting Strength refers to the ability of paper and paperboard materials to withstand bursting or breaking when subjected to external forces, typically measured using a bursting strength tester. The result indicates the maximum force that the paper or paperboard can resist per unit area before rupturing, providing insights into the material’s structural strength and durability, particularly relevant in the context of packaging and transportation.

Why is the bursting test always referred to as Mullen Method?

The Mullen Method is named after one of its founders, Emory H. Mullen. Emory H. Mullen, along with other engineers, developed the Bursting Tester in the United States in 1926, which is a specialized instrument for measuring the bursting strength of paper and paperboard. Due to his contributions to the development and promotion of this testing method, it became known as the Mullen Method.
The introduction of the Mullen Method provided the paper and paperboard industry with a standardized and repeatable way to measure a material’s resistance to bursting under pressure. This testing method is widely used in the packaging and related industries to assess the strength of materials, especially when considering the stresses, they may undergo during transportation and packaging processes.
