Overview
The Bursting Strength Tester for Paper is a precision laboratory instrument designed to measure the bursting strength of paper, cardboard, and packaging materials using the internationally recognized Mullen testing principle. This advanced testing machine determines the pressure required to rupture a sheet material, helping manufacturers evaluate the durability, quality, and reliability of packaging products.
Widely used in paper mills, packaging industries, research laboratories, and quality control departments, the bursting tester ensures that materials meet international quality standards before production or shipment.
Applications
The paper bursting strength tester is suitable for testing a wide range of materials including:
Paper and paperboard
Corrugated board and grey board
Color boxes and packaging materials
Aluminum foil and thin films
Rubber and plastic sheets
Silk fabrics and cotton cloth
Its versatility makes it an essential quality testing instrument for paper and packaging manufacturers.
Key Functions
This instrument accurately measures the bursting pressure required to break sheet materials, providing critical data for evaluating material strength. Key testing capabilities include:
Measurement of bursting strength of paper and cardboard
Quality assessment of corrugated packaging materials
Strength analysis of non-paper sheet materials
Real-time monitoring of pressure curves during testing
Data storage and export for laboratory reporting
These functions allow manufacturers to improve product quality and meet international testing standards.
