A Paper Bursting Strength Tester is a precision laboratory instrument used to measure how much pressure paper, kraft paper, carton board, or corrugated board can withstand before it ruptures. For paper mills, carton box manufacturers, and packaging quality control teams, this equipment is essential for confirming that materials can survive handling, stacking, and shipping stress. Amith Garment Services offers a paper bursting strength tester built for accuracy, repeatability, and dependable daily performance.
Product Overview
The Paper Bursting Strength Tester from Amith Garment Services is designed for packaging laboratories, corrugated box manufacturers, and export-focused production units that need accurate, standards-compliant bursting test results. The instrument applies controlled hydraulic pressure to a clamped paper or board specimen and records the precise pressure at which the material fails. With a digital display, microprocessor-based controls, and automatic data capture, it minimizes manual reading errors common with older analog instruments.
Whether your facility tests kraft paper, multi-ply carton board, or corrugated packaging material, this tester delivers consistent results suitable for in-house quality checks, third-party inspections, and export documentation. It is equally effective as a dedicated Carton Bursting Strength Tester and as a general-purpose Bursting Strength Tester for Carton Box production lines.
What is a Paper Bursting Strength Tester?
A paper bursting strength tester is laboratory equipment used to determine the maximum hydraulic pressure a sheet of paper or board can endure before it bursts. This method, commonly known as the Mullen burst test, uses electronic sensors and a microprocessor to capture pressure readings with precision, then displays the bursting strength value on a digital screen. It is a core instrument in paper quality testing and packaging quality inspection across the paper, carton, and corrugated board industries.
Why Bursting Strength Testing is Important?
Bursting strength testing reveals whether a paper or board material can withstand the physical stress it will face during packing, stacking, and transport. Weak packaging materials lead to product damage, customer complaints, and rejected shipments at export checkpoints.
- Confirms compliance with buyer specifications and packaging quality standards.
- Reduces the risk of carton failure during stacking and transit.
- Supports consistent quality across paper and board production batches.
- Provides documented evidence for export certification and quality audits.
- Helps R&D teams select the right paper grade or board thickness for each application.
How a Paper Bursting Strength Tester Works
The working principle of this paper testing equipment is simple yet highly precise when properly calibrated. Here is the step-by-step process:
- Sample Preparation: A paper, kraft paper, or carton board specimen is cut to the required test size and conditioned under standard atmospheric conditions.
- Clamping: The specimen is securely clamped over a circular rubber diaphragm, preventing slippage during the test.
- Pressure Application: Hydraulic fluid is pumped beneath the diaphragm, causing it to expand upward against the clamped sample.
- Stress Build-Up: As pressure rises, the diaphragm pushes against the material, gradually increasing tension across its surface.
- Bursting Point Detection: The instant the paper or board ruptures, the built-in sensor captures the exact pressure value at failure.
- Digital Display: The bursting strength value appears instantly on the digital screen, with many models able to store or print the result automatically.
