Bursting strength is a crucial property of paper, paperboard, and corrugated board for assessing their durability to withstand maximum pressure before they rupture. It is measured by applying a controlled hydraulic pressure to a sample of paper, paperboard, or corrugated board until it bursts. The pressure at which the material ruptured is said to be its bursting strength. The test results of bursting are expressed in kilopascals (kPa) or kilogram-force per square centimeter (kg/cm2) units. Bursting Strength testing is considered to be a significant parameter for the evaluation of paper, paperboard, and corrugated board since the material that has poor bursting strength directly influences the performance of packaging, its quality, and economic efficiency.
UEC’s Bursting Strength Testers are based on the Mullen principle and come in various models depending on the user’s budget and required test reporting parameters. The product line begins with a basic hand wheel clamping model that shows measurements on a bourdon pressure gauge and extends to the advanced NexGen touch screen model, which incorporates cutting-edge technology to deliver precise results and a graphical display of the data obtained. It offers enhanced usability, repeatability, and a true representation of the sample’s performance. Additional features such as automatic clamping, configurable test parameters, wireless PC connectivity, and comprehensive test reporting give key insights into the test results instantly. All of this increased efficiency allows mills to make timely process adjustments and optimize raw material usage.
Explore a comprehensive range of variants designed to match your budget and specific testing needs.
Mullen Bursting Strength Tester (UEC-1010 A1)
Users with budget constraints who wish to assess fundamental bursting characteristics, such as maximum bursting strength, are advised to choose the UEC-1010 AI/BI. This compact unit operates through a simple push-button operation. The sample is clamped with a handwheel and the maximum pressure of the paper, paperboard or corrugated board sample at the time of rupture is recorded on a bourdon pressure gauge.
Digital Bursting Strength Tester (UEC-1010 BII)
The next upgrade is our Digital Bursting Strength Tester (UEC-1010 AII/BII) equipped with hand wheel clamping and a digital control panel. Users now have the capability to feed the GSM of paper, save the test data, and obtain results including the mean of Bursting Strength and Burst Factor. The diaphragm after rupture, returns automatically upon completion of the test.
Bursting Strength Tester LW (UEC-1010 CI)
Our range of burst testers just doesn’t end here. The Bursting Strength Tester with pneumatic clamping (UEC-1010 CI/DI) is the preferred option among customers. The LW or lightweight version is microprocessor-based and comes complete with memory for retaining peak value. It has automatic zero setting and overload, and over-travel protection facilities. Automatic clamping of the test specimen also allows for quick operation, uniform clamping across the specimen, and improved repeatability of tests.
Bursting Strength Tester NexGen (UEC-1010 CII)
Users can also upgrade to the NexGen touchscreen control system (UEC-1010 CII/DII) that not only provides a graphical representation of test results but also reports additional test parameters beyond the Bursting Strength and Burst Factor. The newly developed platform provides a high level of detail on the sample, including its Burst Strength Index, Burst Energy Absorption, Burst Energy Absorption Index, maximum and minimum value, standard deviation, and coefficient of variation.
The software allows configurable test parameters, live monitoring of test results, comprehensive data analysis, wireless connectivity, auto cycle operation, and many more. The upgrade provides key data insights that are often overlooked or difficult to measure. With this option, users can perform hundreds of tests rapidly and make accurate data-driven decisions to optimize their process.
Double Head Bursting Strength Tester NexGen (UEC-1010 EII)
For users looking to test both paper/paperboard and corrugated board samples in one equipment, our NexGen Double Head Bursting Strength Tester is an ideal choice. The unit offers the same functionality as the Bursting Strength Testers with pneumatic clamping, but has slight modifications to the software to include the operation of both heads from one touch screen control panel. The highly advacnced IoT based platform provides an extensive reporting of results along with a graphical representation of data points. The test results can also be printed or downloaded as a PDF or spreadsheet with just a single click.
With this upgrade, users save considerable investment and time to perform independent calculations on different testers. Low and high GSM samples can be tested rapidly on the two heads with just a few clicks, and allow the user to generate a detailed report on a single page.
UEC’s vast offering of Bursting Strength Testers for paper, paperboard, corrugated board, and fiber board samples will not only provide users with an important understanding of the sample’s performance but will help them make informed decisions in their processes or supply chain. With a variety of offerings available, users can invest depending on their budget and testing needs.
