  1. Packaging Industry: The Mullen Tester is widely used in the packaging industry to assess the strength and durability of corrugated boxes, cartons, and packaging materials. It helps determine the suitability of materials for containing and protecting goods during shipping and handling.
  2. Quality Control: Manufacturers and converters of paper products use the Mullen Tester as part of their quality control processes. It allows them to ensure that materials meet specified strength requirements and comply with industry standards and regulations.
  3. Product Development: The Mullen Tester is also utilized in product development and research to evaluate different materials and designs for packaging solutions. It helps in optimizing packaging designs for maximum protection and cost-effectiveness.



  • Standardized Testing: Follow standardized testing procedures and protocols recommended by organizations such as ASTM International or TAPPI (Technical Association of the Pulp and Paper Industry) when using the Mullen Tester.
  • Sample Preparation: Prepare samples of uniform size and condition for testing to ensure consistent and accurate results. Avoid samples with defects or irregularities that could affect the testing outcome.
  • Calibration: Regularly calibrate the Mullen Tester according to manufacturer guidelines to maintain accuracy and reliability in measurements.
  • Interpretation of Results: Understand how to interpret the results obtained from the Mullen Tester, including burst strength values and any relevant specifications or tolerances applicable to the tested materials.
