The BNP-01 Board Bursting Tester is a highly specialized instrument used to evaluate the bursting strength of paperboard, a critical property for determining the material's durability and performance in packaging applications. This tester operates by applying hydraulic pressure to a circular diaphragm, pushing against the test material until it bursts. The Board Bursting Tester is capable of measuring bursting strengths in the range of 350 kPa to 5,500 kPa, making it ideal for testing various types of board, including corrugated board, solid fiberboard, and more. With the ability to test both low and high bursting strengths, it provides manufacturers with crucial insights into the board's ability to withstand pressure during packaging, transportation, and handling.
The Board Bursting Tester is an essential tool for manufacturers in industries such as packaging, food, medicine, and beverage. By accurately measuring the bursting strength of board materials, it helps manufacturers ensure that their products maintain integrity and are less likely to be damaged during transit.
The BNP-01 Board Bursting Tester operates by placing a sample of board over a circular elastic diaphragm, which is rigidly clamped at the edges while being free to bulge upwards. Hydraulic fluid is pumped at a constant rate into the diaphragm, causing it to bulge until the test material ruptures. The bursting strength is determined by the maximum pressure applied before the rupture occurs. This principle allows the Board Bursting Tester to simulate real-world conditions in which packaging materials may be exposed to internal or external pressure, such as during shipping or storage.
The BNP-01 Board Bursting Tester is crucial for testing the physical properties of packaging materials, especially in industries where packaging strength is vital for protecting goods during transportation. Its applications include:
The Board Bursting Tester complies with several internationally recognized standards, ensuring it meets the highest industry requirements for material testing. These standards include:
Understanding the bursting strength of board is essential for manufacturers to assess the material’s ability to resist rupture under pressure. This test is a crucial part of the packaging quality assurance process, especially when dealing with products that will be exposed to high levels of stress during transportation. The Board Bursting Tester helps reduce resource waste and transportation losses due to damaged products, making it an indispensable tool for industries where product integrity is critical.
